I would use babelfish to translate, but technical stuff doesn’t seem to translate well.
The main part is the Windows Start, Run and type rundll32 wbemupgd, UpgradeRepository (or copy and paste the command) and click OK.
If that didn’t work use the quoted text to open a CMD window, stop the service, rename the troublesome Repository folder and restart the services and hopefully windows will rebuild the repository on reboot.
