    Anyone know how to restore Windows certs back to default? Or force a sync with Windows Update? I see all sorts of complicated things online, couldn't get it to work (or didn't know where to start from). If no easy way, is it possible to "export" all certs from a clean install and "import" into this corrupt install?

    TIA

    P.S. Thread in Windows 8 forum because corrupt pc is currently running 8.1

    maybe setting time and date in bios solves de problem.
    checking MotherboardĀ“s battery status from time to time is a good practice.

    What certificates you talking about?
    If you talk about certmgr.msc then it's not nessary to restore them, Windows checks every xy hours for the certificates itself and temporarily stores the needed ones (no visible by any tool or certmgr.msc) in a temp repo. As long you not disabled or blacklisted manually the certificates it will restore the deleted ones automatically as soon as there is a request or update check.

    Code:
    net stop cryptSvc /y
    takeown /f "%WINDIR%\System32\catroot2" /a
    icacls "%WINDIR%\System32\catroot2" /grant:r Administrators:F /c
    ren "%WINDIR%\System32\catroot2" "catroot2.bak"
    net start cryptSvc
    It might take up to an hour, till certificates are recreated, you will notice an increased CPU usage. In case of problems, just restore the backup.
    Code:
    ren "%WINDIR%\System32\catroot2.bak" "catroot2"
