[German]Sometimes Windows update keeps installing the same update over and over again. Here is a fix how to stop that endless update loop.
It's mandatory, that Windows still is able to boot up and the user is able to log into the user account.
1. Open an administrative command prompt window (enter cmd in search box, right click the search result and select the context menu command Run as administrator.
2. Enter the commands listed below into the command prompt window and confirm each command with enter.
The first sequence tries to stop several services:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
If a command fails, just ignore it. After stopping the services, try to rename some folders using the commands below.
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
You can also use Windows Explorer to rename the two folders. This will be more comfortable then using a command prompt window.The goal of this renaming operation is to remove the pending updates. Afterward you can try to re-launch the already stopped services.
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Or try to restart your Windows machine to activate the services again. After successful execution of the commands given above, installing an update over and over again should be ended.
After ending the update loop, you should fix the root cause. In many cases, at third party system tool like antivirus software is blocking update installation. So uninstall these tools and use a clean tool provided by vendors to remove remaining install files.
