I have spent the last 2 hours trying to fix this problem, including running the Windows Update Trouble Shooter plus a host of other suggestions, but nothing works.
Never had any issues with Windows 10 updates till now.
I don't know what to do.

Dont sweat it! Its happening to everybody. You can try this ---
Windows + R, type services.msc and click ok, locate windows update service, right-click on it select stop.
Search in task bar for C:\Windows\SoftwareDistribution select all files and deleted them.
Go to Administrative Command prompt enter dism /online /cleanup-image /startcomponentcleanup This takes a while to perform.
When completed. Enter sfc /scannow when it is finished restart computer.
After restart Check for updates.
