Whatever the reason, here are some solutions you may apply to fix almost every Windows update-related problem.

Windows 10 update stuck checking

If Your PC shows stuck at 100% when you’re performing a Windows update, you can try to force restart your PC first.

  1. Make sure you have a working internet connection So that Windows downloads the updated files from the Microsoft server. Also, check on your system installation drive (C drive) to have sufficient free space to download and install Windows updates. Or you can run Disk Cleanup tool to free up some disk space.
  2. Sometimes, updates can be large and require a long time to download. If a particular update is stuck at, say, 95% for an hour or two – don’t panic. However, there may be an issue if that figure doesn’t shift after hours
  3. Disable your antivirus software — security software may sometimes block Windows 10 updates. Turn off your antivirus, download and install the updates and then turn it on again.

Check the Windows update service

Open Windows services (services.msc) and check Windows update and its related services are running.

  • Press Windows Key + R and type services.msc, Click on OK or hit the Enter key.
  • In the services Window scroll down to Windows Update Service.
  • Right-click on the service and click on Properties.
  • Make sure the Startup type is set to Automatic and Service status is started.
  • Click Apply and ok.

You may repeat the above steps for Background Intelligent Transfer Service (BITS).

Clean boot Windows 10

Clean booting your computer may also help, If any third-party software causes conflict download & install Windows updates. Here’s how to do this:

Performing a clean boot, which can avoid software conflicts while installing Windows updates

  • Press the Windows key + R, type msconfig and click ok to open the system configuration window,
  • Move to the services tab, checkmark on Hide all Microsoft services then click on Disable all.
  • Now move to the Startup tab and click on Open Task Manager
  • Here Disable all the unnecessary services running there.

Restart your computer and check for updates again.

Free up Disk Space

If the system driver is usually C, and run out of space, the Windows update may stuck downloading because of the lack of free space on the drive. You can free up disk space by following the tips below.

First If you have multiple partitions on your computer we recommend Move files to a different drive (For example D drive) or if possible move some large files to an external disk.

We recommend remove or uninstalling apps and programs on your PC that you don’t use. To check which apps use more space open the Settings menu and go to Apps > Apps & Features and choose Sort by Size.

Run the built-in disk cleanup utility, which can help you clear up space by removing various files — including temporary internet files, system error memory dump files and even previous Windows installations that may still be hanging around.

In addition, remove external devices while checking for Windows updates to prevent any driver conflict that may prevent downloading or installing Windows updates on your PC. Some Windows users reported that after they disconnect all the USB peripherals from their PCs, the update process completes quickly.

Clear buggy update (cache)

If the Windows 10 update is stuck during download at 0% or 99% or completely failed to install, it might be that something went wrong with the file itself. Clearing the folder where all of the update files are stored will force Windows Update to download fresh files.

It shouldn’t cause any damage to your PC – you’ll only really be deleting temporary Windows Update files – but we’d recommend setting up a System Restore point before going any further.

  • To do this Type services.msc on the start menu search and hit the enter key. Then look for Windows update service, right-click on it, and select stop. Do the same with its related service BITS ( Background Intelligent Transfer Service ).

Or you can use the command net stop wuauserv and net stop bits to stop these services.

  • Go to the following location C:\Windows\SoftwareDistribution\Download And Delete everything in the folder, but do not delete the folder itself. To do so, press CTRL + A to select everything and then press Delete to remove the files.

Note: If the files can’t be deleted because they’re in use, you’ll need to restart your PC. Turn off the two Windows Update services and then try to delete the files again.

  • Again open Windows services and restart the services (windows update, BITS) that you previously stopped. or Use the command net start wuauserv and net start bits to Bring up these services.

Run Windows Update troubleshooter

After clearing Buggy update files simply run the Windows update troubleshooter to check and fix any other problem preventing the Windows update to download and installing. To run the update troubleshooter.
