Windows 10

[Rbspetne]

I have 2 computers, both Dell Optiplex 3060 desktops part of a Windows domain, with Windows 

Pro 10.0.18363 that consistently fail to update. 

 I have tried updates via the Settings check for updates and manually via Microsoft download Media Creation Tool as well as ISO. 

Also Dell Command update indicates all drivers are current. The latest failure recorded the event log message:"Installation Failure: Windows failed to install the following update with error 0x80242016: Feature update to Windows 10, version 21H2"Some of the things I have tried include:clean bootunplugged external USB devicesrenamed Software Distribution folderWindows Update troubleshootersfc /scannowDISM /online commands for /cleanup-image and /restoreHealthreset Windows Update componentsHas anyone else experienced this and found a solution?

To solve this issue, open admin cmd and execute the following:

dism /online /cleanup-image /checkhealth
dism /online /cleanup-image /restorehealth
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
net start wuauserv
net start cryptSvc

Then, execute the Windows update troubleshooter:

There's also the handy Windows repair install technique. Quick and very easy. All you need is Windows 10 install media or a Windows 10 ISO image present on the system, either of which can be created with the Windows media creation tool.

In many cases, simply rebooting your computer and rerunning the update will fix your problem. If Windows 10 has multiple updates queued, it's pretty standard for one to fail during the initial update process. In that case, you can usually get things working again by rebooting and starting the update process again
