If you’re connecting your PC to the internet, you’ll need to keep it up-to-date. Microsoft regularly issues important security updates, bug fixes, and new feature releases for Windows 10 to improve the overall user experience. If you don’t keep Windows updated, you’ll be putting your PC (and the data held on it) at risk.

Most of the time, Windows can handle the update process without any user input. From time to time, however, Windows just won’t install updates, leaving them stuck in limbo. If you want to fix when a Windows 10 update is stuck, here’s what you’ll need to do.

Give It Time (Then Force A Restart)

It might seem like the obvious answer to the problem, but sometimes the easiest solution when a Windows 10 update is stuck is just to give it a bit of extra time. The progress bar might not be moving, but that doesn’t necessarily mean that nothing is happening.

Windows releases monthly cumulative updates that bundle together other update releases into a single, easy-to-install download and installation. You’ll also see much larger feature updates released on a twice-yearly basis. 

These are big updates to the Windows operating system that include new features and changes to the overall user experience, as well as important bug fixes. These updates can be big and can take time to complete. 

If your Windows 10 update is stuck for an hour or longer, then force a restart. Only do this if your PC really isn’t responding, as restarting in the middle of an update cycle can break your system, forcing you to reinstall Windows to get things running again.

Run Windows Update Troubleshooter

While Windows is pretty good at resolving issues with updates on its own, it can be useful to turn to the built-in Windows Troubleshooter tool to help diagnose and fix any problems with your system.

  • You can find and run this tool from the Windows Settings menu. To run this, right-click the Windows Start menu and click Settings. From there, click Update & Security > Troubleshoot to access the troubleshooting tool.
  • If Windows has any immediate recommendations for you, including tips to help improve the update experience, these’ll be listed under the Recommended troubleshooting section at the top of the Troubleshoot menu.
  • To run the Windows 10 Update Troubleshooter, click Windows Update under the Get up and running section, then press Run the troubleshooter to begin the tool.
  • The tool will begin in a new window, and will automatically begin checking your PC for problems or issues. If it can find a problem with a stuck update, it’ll fix this for you automatically, or inform you on what to do next. If Windows detects no problems, it’ll invite you to give feedback or close the tool.

The Windows Troubleshooter can’t fix every problem, but if an obvious issue is detected, it will attempt to resolve it. If it can’t, you’ll need to try one of the steps below instead.

Delete Temporary Windows Update Files

A broken Windows 10 update can sometimes be fixed by deleting the temporary files that Windows downloads for updates. This can force Windows to download the files again, then attempt a reinstallation.

If the Windows 10 update is stuck because of broken or corrupted files, this should resolve the problem.

  • To do this, you’ll first need to disable some Windows services related to Windows Update. To do this, right-click the Windows Start menu and click Windows PowerShell (Admin). In the PowerShell window that opens, type net stop wuauserv and net stop bits to first disable these services.
  • Once these services are disabled, type Remove-Item -path c:\Windows\SoftwareDistribution. This will delete the folder containing your temporary Windows update files. Type Y or A to confirm. You can also delete these files manually using Windows File Explorer.
  • Once this process is complete, type net start wuauserv and net start bits to restart your Windows Update services.
  • You can then check for updates again manually by right-clicking the Start menu and clicking Settings. From there, click Windows Update > Check for Updates to access and run Windows Update. If an update has previously failed, this should force Windows to download the update again and attempt to reinstall it.

Manually Update Your PC From Microsoft Update Catalog

Downloading and manually updating your Windows 10 PC can sometimes get around issues with Windows Update. You can look for new updates using the Microsoft Update Catalog website.

Don’t let the outdated interface confuse you, as this contains all updates released by Windows for its desktop and server operating systems. You’ll need to know the reference code for the update you’re looking for, or you can search by the update name (for instance, Windows 10 cumulative update).

  • Search for the update using the search tool on the Microsoft Update Catalog website. Once you’ve found the update you’re looking for, click the Download button.
  • Once downloaded, open the archive file containing your update and extract it. Each update should contain a setup executable file—double click this to run the update.
  • Follow the instructions on-screen for your update (if required). Once the update has completed, return to Windows Update (Windows Settings > Update & Security > Windows Update) and check for any additional updates.

If a single update is causing the problem, then this should allow you to proceed with further updates. If more than one update is broken, however, then this could be a time-consuming fix, and you may need to look at other options.

Revert Your Windows Installation Using System Restore

A broken Windows 10 update can’t always be fixed, especially if there’s a problem with your Windows installation. To get around this problem, you can use Windows System Restore to revert Windows back to an early point in time.

  • To access your System Restore points, press Win + R to open the Run dialog box. From here, type sysdm.cpl SystemProperties and click OK.
  • In the System Properties window, click System Restore
  • In the System Restore window, click Next, then select a Windows Restore point before your failed update. Click Next to continue.
  • Click Finish to confirm. This will restore Windows to the previous point in time you selected.

Once the restore process is complete, you should be able to run Windows Update again afresh. If the problem isn’t resolved, however, you may need to look at wiping and reinstalling Windows to get your system updating correctly again.

Keeping Windows Updated

Without updates, you’ll be left dealing with bugs, malware infections, and missing features. Windows 10 is a rolling release operating system, meaning it continues to be updated and developed for an improved user experience. Your Windows 10 updates may take forever, but that’s no reason to disable them.

If you are having problems, then you can bypass Microsoft’s own systems entirely by updating Windows without Windows Update, thanks to third-party software. In most cases, however, you’re best leaving Windows to do its thing, and following the steps above to troubleshoot any of the most common issues with broken or stuck Windows 10 updates.


It might be a safe bet to make that Microsoft will never completely get the hang of delivering updates to everyone without any problems. The least it can do is limit update problems to major feature releases but it seems the cumulative updates have their own problems. Cumulative updates are released monthly and on principle, they should install without any hiccups. Since December, 2017 though, users have been unable to install them. They download without any problems but fail to install. In the worst scenarios, users are stuck in a boot loop. The stuck cumulative updates are plaguing users again. Here’s one possible way to fix them.

Fix Stuck Cumulative Updates

This fix should work if cumulative updates fail to install, fail to download, or fail to be detected. The fix has to do with deferring updates and you will need administrative rights on your system to apply it.

Open the Settings app and go to the Update & Security group of settings. Go to the Windows Updates tab. Scroll down, and click ‘Advanced options’.

On the Advanced Options screen, you have two dropdowns that let you choose when updates are delivered. There are two types of updates; feature and quality, and you can defer them individually. Open both dropdowns and set the value to 5 days. Return to the main Windows Update tab and allow it to check for updates again. This time, they ought to download and you can manually install them, or allow Windows 10 to install them during your off hours.

Once the updates have been installed, you can change the deferment time back to 0 days.

Blocking Updates

If you have any apps installed that block Windows updates, you should either disable them or uninstall them. These apps work by disabling essential services that need to be running in order for new updates to be detected and installed. These apps may be the reason you’re having trouble installing updates. If you use them to prevent a sudden system restart, it’s better to use the deferred updates feature instead. Additionally, you shouldn’t defer updates unless you have a good reason to e.g., the next version breaks a driver or essential component on your PC. When an update is available, set aside a time to install it.

If you have been using apps to block updates, or if the above solution doesn’t work for you try resetting the Windows update agent. It’s a fairly basic method for fixing stuck Windows 10 updates.

How to fix a stuck Windows 10 update

Step 2. Restart your PC. Resetting your PC mid-installation is a cardinal sin and expressly warned against by manufacturers, but if your update is genuinely stuck then you haven't got a lot of options. Use your computer's physical power or reset button, and remember that you may have to hold it down.

Step 3. Boot into Safe Mode. Accessible from the Startup Settings menu, this mode disables everything but the absolute essentials Windows needs to run, ensuring that any software conflicts that could be interfering with the update are removed. After the update installs, you can restart Windows to exit Safe Mode.

The Windows 10 safe mode user interface

Step 4. Perform a System Restore. In order to safeguard against this type of thing, Windows will usually create a restore point just before applying an update, so you can roll it back if there are any problems. You can access the System Restore function from Safe Mode, or from the Advanced Startup Options if that doesn't work.

Step 5. Try a Startup Repair. A more in-depth fix than just doing a System Restore, the Startup Repair tool (also accessible from the Advanced Startup Options screen) can sometimes fix underlying issues that may be hampering the update process.

Step 6. Perform a clean Windows installation. This is pretty much the 'nuclear option', but if all else fails, you may be forced to simply erase your previous copy of Windows and simply start from scratch. Be warned, though, that this will erase your entire hard drive, so make sure that any vital data is as thoroughly backed up as possible beforehand.

How to fix a stuck Windows update

Found a Windows 10 update is stuck? Thankfully, a stuck Windows 10 update isn’t the worst thing in the world. In fact, it’s not entirely unavoidable. With so many hardware and software configurations out there, there's always the chance that some unexpected problem will crop up.

Operating system updates can be a real chore, and you might not care for them. But like taxes and car MOTs, they are a necessary evil, essential for a happy and peaceful computing life. They keep you protected by squashing nasty bugs, and your OS running as smoothly as possible.

Still, installing a new update won’t always run smoothly. Even with Microsoft trying to make the process as pain-free as possible in recent versions of Windows, getting a Windows 10 update stuck may still happen to you. When it does, you’ll be happy to know that there’s almost always a fix.

So don’t panic and read on. We've got you covered. Here are a few fixes when you end up with a Windows 10 update that’s stuck.

How to fix a stuck Windows update

  1. Make sure the updates really are stuck
  2. Turn it off and on again
  3. Check the Windows Update utility
  4. Run Microsoft's troubleshooter program
  5. Launch Windows in Safe Mode
  6. Go back in time with System Restore
  7. Delete the Windows Update file cache yourself
  8. Launch a thorough virus scan 
  9. Run a full Windows reset

1. Make sure the updates really are stuck

We're going to cover a lot of ground here for several versions of Windows and a variety of 'stuck' scenarios, so you may have to tweak some of these steps to suit your situation and software.

The first point to make is that interfering with updates that aren't actually stuck can cause a host of problems, so you want to make sure they really are stuck.

If you've got the time, and the patience, we'd recommend waiting a couple of hours, especially with slower machines – go and cut the grass or watch a movie. It may seem extreme, but you don't want to start meddling with these fundamental processes unless you really have to.

2. Turn it off and on again

Do you know why "have you tried turning it off and on again" is such an IT support cliché? Because it so often works. There's no magic trick to this – it simply clears out your computer's temporary memory (including any stalled files or processes), and lets Windows start again from scratch with everything on the system.

If your updates are stuck in the background while you still have access to Windows, you can restart as normal; if they're stuck before or after the OS loads, you're going to have to hold down the power button and do a hard reset. This can cause issues itself, so make sure your updates definitely aren't progressing at all.

3. Check the Windows Update utility

In Windows 10 you can find the Windows Update page by launching the Settings app from the Start menu and clicking Update & Security – if there's something wrong and Windows knows what it is then you should find details here. Sometimes you'll just get a message telling you to try the update again at a different time.

If you click 'Advanced options' and then 'View your update history', you can see recently installed updates that were successful, and uninstall some or all of them – again, this can be a handy troubleshooting option. Windows 10 has actually streamlined the update process, so you should be seeing fewer errors.

4. Run Microsoft's troubleshooter program

Microsoft feels your pain: it knows the update process can cause problems every now and again, which is why it's developed a troubleshooter program specifically for it – search the old Control Panel for "troubleshooting", then select 'Fix problems with Windows Update' from the list on-screen.

The link should be available in Windows 7 and 8 too, but if not you can get at it on the web as well. That said, if you haven't yet upgraded to Microsoft's latest and greatest operating system then it's probably still worth your while, as it's more than likely to solve your update problems at the same time.

5. Launch Windows in Safe Mode

Safe Mode is like a restart with extras – only the very basic apps and code that Windows needs to run are loaded into memory, so there's even less chance of a rogue, damaged file interfering with the update. In Windows 10, hold down the Shift key then choose Power and Restart from the Windows sign-in screen.

On the next screen you see pick Troubleshoot, Advanced Options, Startup Settings and Restart, and you should then see the Safe Mode option appear: try running through the update process again if you can. A quick search online will give you Safe Mode instructions for older versions of Windows.

6. Go back in time with System Restore

System Restore has been helpful for solving Windows problems for many a year now, but it happens to be quite well hidden in Windows 10. Go to Control Panel, System, System Protection and then click System Restore. Go through the wizard, then choose 'Show more restore points' to see all your available options.

Pick a time and date, then complete the wizard to go back to how Windows was configured at that point (and hopefully solve your update issues at the same time). The process doesn't affect your personal files or programs, but it may not be available to you depending on how Windows was originally set up.

7. Delete the Windows Update file cache yourself, part 1

If Windows' own troubleshooter doesn't work (see step 4) then you can try and carry out the same process yourself manually: stopping the Windows Update service, deleting the temporary files it's created, then starting Windows Update again. It's a little more involved, but it's not difficult to do.

First, boot up into Safe Mode (see step 5), then access to the command prompt, the most basic of Windows interfaces: right-click on the Start menu, choose Command Prompt (Admin), and a text box should appear. Type "net stop wuauserv" and hit Enter, then follow that with "net stop bits" and hit Enter again.

8. Delete the Windows Update file cache yourself, part 2

Back in Windows proper, navigate to the C:\ Windows\ SoftwareDistribution folder, and delete everything you find therein. You're not going to break anything by doing this – these are just temporary files Windows creates so it knows where it's up to, and Windows Update will create them again from scratch.

With that done, go back to your command prompt window and type "net start wuauserv" (Enter) then "net start bits" (Enter) to get Windows Update and its related background services up and running again; hopefully this trick should be enough to kick-start the update that was previously stuck.

9. Launch a thorough virus scan

One of the more obscure reasons why a Windows update might not be installing is because a virus or some kind of spyware is blocking it: malicious apps like these can often be squashed by Windows security updates, which is why they try and stop the latest patches from being installed on your machine.

Try running a full and thorough virus scan using whatever security software you have installed (you do have some installed, right?). If you think your antivirus software has also been compromised you can download some on-demand scanners, like this one from Microsoft or this one from Dr. Web.

10. Run a full Windows reset

Restoring key Windows files and OS options is a lot easier than it used to be, and 'resetting' Windows 10 basically means putting all the system files back to their factory state without touching your personal files along the way (although you can choose to wipe your drive completely if you want).

You can find the option via the Recovery tab on the Update & Security page in the Settings app – note that third-party apps are removed too, so these will need installing again. Windows 8 offers both 'refresh' and 'reset' options, while on Windows 7 the reset option will typically have been provided by the PC's manufacturer.

Fix 4: Reset Windows Update components

If Windows Update components corrupted, Windows Update may not work properly. Maybe that’s reason behind this issue. To resolve it, try resetting Windows Update components. Here is how to do it:

  1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run dialog. Type cmd and press CtrlShift and Enter at the same time to run Command Prompt as administrator. You’ll be prompted for permission. Click Yes to open Command Prompt.
  2. In Command Prompt, type the command lines below and press Enter on your keyboard after typing each:

    net stop bits
    net stop wuauserv
    net stop appidsvc
    net stop cryptsvc

    Note: The Windows Update related system services will be stopped after executing the command lines above.
  3. In Command Prompt, type the following command lines and press Enter after typing each:

    ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
    ren %systemroot%\system32\catroot2 catroot2.old

    Note: You will rename the SoftwareDistribution and catroot2 folder as SoftwareDistribution.old and catroot2.old after you run these two command lines. These two folders are used by Windows Update to save temporary update files.

    By renaming these two folders, Windows will think these two folders are missing, and Windows will create new ones to store Windows update files. By doing that, you can avoid many Windows Update issues caused by the old corrupted temporary files in these two folders.
  4. In Command Prompt, type the following command lines and press Enter after each:

    net start bits
    net start wuauserv
    net start appidsvc
    net start cryptsvc
