There are a few things you can try to resolve this issue, but before you attempt any of the suggestions below ensure that Windows is backed up to an off-site or external device.
To begin, restart the server.
Restart services
- Login to the server as a local or domain Administrator
- Right click the start menu button and click 'Run'
- Type 'services.msc' without the quotation marks and press enter
- Select the 'Windows Update' service from the list and click 'Restart'
Clear update cache
In the case where an update package was corrupted during download, clearing the update cache may resolve the problem.

folder and delete - Open Settings > Updates and click 'Check for Updates'
Repair the system image
Important core Windows files and registry values can corrupt overtime. Windows comes with an automatic system image repair tool that can be using during normal operation without the risk of downtime.
