When upgrading Windows 10, Windows Update is showing available updates but at the some point it just gets stuck and stops downloading. I faced this issue and my downloading was stuck at 6% as as shown in the picture below.
Follow these steps to Fix Windows Update when it gets stuck:
- Start Windows 10 in Safe Mode
- Delete all files and folders in C:\Windows\SoftwareDistribution
- Restart Windows in normal Mode
- Run Windows Update again
This worked for me and I hope it does for you too.
