    Hi Guys!

    My Win 7 Ultimate System was installed a long time ago and i cant remember which Loader i used. Now i need SP1 but i guess it would kill my activation. Is there a safe way to install SP1 ?
    Thanks for your help!

    Before you attempt anything, download MBR Regenerator and Windows Loader.
    Install SP1 however you see fit and if it breaks your activation, run MBR Regenerator(as administrator), let it do it's job, restart, run Windows Loader(as administrator) and activate.

    Just did a test, installed W7 RTM and activated by DAZ' Windows Loader v2.2.2 and installed "KB976932" (SP1 exe).

    The activation was untouched.
