Fix 1: Remove any USB peripherals and wait for the update process to finish
If you seldom check for Windows updates, it may take a long time for Windows to complete the update process. Maybe your PC is not “stuck” at Windows update, and Windows is just configuring and installing update packages.
If you temporarily don’t need to use your PC, you can just wait for 2 to 3 hour to see if the update process can complete. If there are any USB devices (like printers, USB flash drives, etc.) connected to your PC, you can try removing it from your PC. Some Windows users reported that after they disconnect all the USB peripherals from their PCs, the update process completes quickly.
See if this issue persists after you wait for 2 to 3 hours. If it persists ,try the next fix below to force restart your PC.

If Your PC gets stuck at 100% when you’re performing a Windows update, you need to force restart your PC first. If you don’t know how to do it, you can follow the instruction below:
- Press and keep holding the power button on your computer case until your PC shuts down.
- Disconnect any external power supply or remove the battery from your laptop.

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:
- On your keyboard, press the Windows logo key and R at the same time to invoke the Run dialog. Type cmd and press Ctrl, Shift and Enter at the same time to run Command Prompt as administrator. You’ll be prompted for permission. Click Yes to open Command Prompt.

- 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.
- 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
Note: After you executed the command lines above, you start the Windows Update related system services.
