Issue

Windows 10 PC cannot finish downloading updates. It always gets stuck on the same percentage no matter what.

Resolution

The issue was resolved by deleting everything in “C:\Windows\SoftwareDistribution” folder. I had hard time deleting some files in this folder even after stopping Windows Update services, so I finished this in Safe Mode. To boot to Safe Mode in Windows 10:

• Open Run dialong (WIN + R)
• Type msconfig and press Enter
• In System Configuration window, Boot tab, select Safe Mode and click OK
• Confirm Restart in next dialog.
