I previously had client computers (Windows 7) configured for using WSUS. When we went to take the Windows 10 upgrades, we were told that Windows Server Update Service is incompatible with Windows 10 and should be manually removed. We hadn't been making any substantial use of WSUS, so I uninstalled the role from our 2012 server, however the installer on the clients is still reporting the WSUS agent as installed.
How can I manually remove the WSUS alterations to the Windows Update agent in order to get the Windows 10 upgrade working?
