WSUS was a necessary evil in the Windows 7 days. Today Windows 10 can still be messed up and we are still Beta testers, but the bad guys are taking less time to reverse engineer the Microsoft patches which makes delays in updating risky.
Uninstalling WSUS still leaves all of your servers and workstations in limbo; they don’t have a local server and they won’t goto microsoft direct to get their updates.
Here is the Powershell code that needs to be run on EVERY workstation to reverse the WSUS setup.
Stop-Service -Name wuauserv
Remove-Item HKLM:\Software\Policies\Microsoft\Windows\WindowsUpdate -Recurse
Start-Service -name wuauserv
