  1. well,how can i use the hotfix and install it if i can’t log in?

  3. TripleA

    Hello, unfortunately this does happen all the time!
    Since about two months now I’m frequently restarting the system and trying to login as an admin but encounter everytime the same situation: Windows 7 freezes at logon with blue swirl animation continuing forever.
    I tried several methods to circumvent this like starting in “Safe Mode”, “Windows Repair” using the original installation disc, etc.
    As long as I’m not able to login I see only a reinstallation of W7 (and beginning from scratch regarding all the many different program installations on the C-Drive) as the solution, although I still hope somebody has a better solution for me. Maybe there’s a trick to install the fix without the need to logon interactively?

    Does a better solution exist somewhere out there?? Please help.

    Thanks a million!
