Have attempted to resolve with " FIXIT" , removed virus and malware security or clean boot.
First, use FixIt for Windows update and try delete or rename %windir%/SoftwareDistribution
If rename SoftwareDistribution not solve the problem, try this:
1. Open Regedit
2. Go to HKLM\Components
3. Delete or rename REG_DWORD "pendingrequired=1"
Are there any restarts pending after installing updates?
