Troubleshooting Windows Update problems

Updated October 1, 2024

When it comes to repairing Windows computers, there are a couple of problems that I get a lot of help requests. One of them is when a computer cannot get updates to Windows. So here are a few of my favorite resources for fixing Windows Update.

Troubleshooting Windows Update problems

There are several reasons why Windows Update can fail. There could be corrupted files or folders; the different services that Windows Update requires are not starting, registry errors, etc. The following is a list of some procedures I use to repair Windows Update.

Remember to always restart your computer after running any of these procedures before trying Windows Update again.

Windows Update Troubleshooter

Windows 10 and Windows 11 have several troubleshooters built-in, including one for Windows Update. All of the Troubleshooters are located in Windows Settings. There are a few different ways to get to Windows Settings.

How to access the Windows Update troubleshooter in Windows 11

You can find all of the troubleshooters for Windows 11 in the Settings app. To get to the Settings app, do one of the following:

  • Left-click on the Start Windows logo menu and left-click on Settings (the gear icon)
  • Right-click on the Start Windows logo menu or press the Windows logo key Windows logo + X and select Settings from the Power User menu
  • Press the Windows logo key Windows logo + I

The Settings app should open with the Home category highlighted in the left-hand column. Left-click on the System category in the left-hand column, scroll down the right-hand column, select Troubleshoot, Other troubleshooters, and then left-click on the Run button on the right-hand side of Windows Update.

How to access the Windows Update troubleshooter in Windows 10

You can find all of the troubleshooters for Windows 10 in the Settings app. To get to the Settings app, do one of the following:

  • Left-click on the Start Windows logo menu and left-click on Settings (the gear icon)
  • Right-click on the Start Windows logo menu or press the Windows logo key Windows logo + X and select Settings from the Power User menu
  • Press the Windows logo key Windows logo + I

Once you open Windows Settings, select Update and Security, then Troubleshoot in the left-hand column. In the right-hand column, select Additional troubleshooters, then select Windows Update.

So if the Windows Update Troubleshooter (repair) did not fix the issue, you could attempt to reset the components that Windows Update uses. The following link gives complete instructions on how to manually reset the Windows Update components, plus some additional resources.

Reset Windows Update components

There is another way to reset the Windows Update components. The Reset Windows Update Tool is a script-based application that performs the same functions as the instructions above. Along with resetting Windows Update components, it can run Secure File Checker (see below), repair invalid registry keys, and repair the Windows system image using DISM (see below).

Check your drive for errors

If you have run the Windows Update troubleshooters (repair/reset) and Windows Update is still not functioning correctly, it's time to do some general system checks. Sometimes there can be an error(s) with the file system that does not allow the troubleshooters to fix the issue(s). I have had this problem many times before. There is nothing worse than feeling like a dog chasing his tail. At this point, check your drive for errors by running checkdisk.

Once you are done with a checkdisk, go ahead and rerun the Windows Update troubleshooter. First, run the repair troubleshooter and try checking for updates. If it doesn't fix it, run the reset troubleshooter. If Windows Update still won't work, then it is time to check system files.

Check system files

SFC

Windows has a built-in program called System File Checker (SFC) to check system files for corruption and incorrect versions. SFC is run inside of an administrative command prompt. Just follow the link below for your version of Windows for instructions on how to bring up an admin command prompt.

SFC is the same in all of the currently supported versions of Windows. Here is the link to the most detailed instructions for SFC (Windows 10, Windows 11).

Once you are done running SFC and have corrected any problems it may have found, try running Windows Update. If it still doesn't work, try running the troubleshooters (repair/reset) one at a time, running Windows Update in between. If you again cannot run Windows Update successfully, it may be time to run the most advanced system corruption repair tools.

DISM

Deployment Image Servicing and Management (DISM) is the complete way of checking for file corruption in Windows. The link to the instructions on how to run it is below. DISM is meant to be used by advanced users, so if you don't feel comfortable running this program, please contact a local computer repair shop like Geeks in Phoenix for assistance.

Fix Windows Update errors by using the DISM

After running DISM, check again to see if Windows Update will work. If Windows Update still does not work, it may be time to perform a repair upgrade to Windows 10 / Windows 11.
