"An Unauthorized Change was made to Windows" - CANT GET PAST BOOT LOGON W/O GETTING MESSAGE! HELP! RRS feed

  • Question

  • I've ran into an error on my Windows Vista Busineed 32-bit installation.




    I've tried every step here from removing programs, which were recenty installed before the crash, to running chkdsk and disk cleanup.


    No luck.


    Note: I installed Apple Quicktime and it refuses to uninstall in safe mode due to the Windows Installer Service not being accessable through safe mode. Any way to uninstall it?


    How can I remove it if I can't even get past the boot logon without it saying "An unauthorized change was made to windows" error message.


    Note: I've also ran WGA and my windows is genuined, however my computer refuses to start in normal mode.

  • Because this forum is dedicated to validation issues, you’ll need to contact outside support for the expertise necessary to troubleshoot your non-validation related issue.  You can do so by posting or searching in the Vista pubic newsgroups, found here: http://windowshelp.microsoft.com/communities/newsgroups/en-us/default.mspx or by following this link to Product Support Services.  Microsoft has a 90 day free support period that starts on the day you first acquire Vista. 

    If you bought your computer pre-installed with Vista either from a computer store or an original equipment manufacturer (OEM) like Dell or Gateway, you’ll need to contact them for support.
