    Hmmm so if i right click on replacer.cmd, and open it, using run as administrator, is that sufficient? Or do i need to modify my user account? I’m using the default account that was set up during installation. Thanks!

  2. FalseLogic says

    Ok, I patched the files, but now I can’t even fully boot my computer. I continually get an error stating that SECBASE.DLL is missing from my computer, but I can’t find any way to fix it.

  3. says

    Windows Explorer doesn’t work after replacing the system files and rebooting my computer. (ocurrs in 7057 and 7100 builds)

    It’s a bug??

    My system info:

    Microsoft Windows 7 RC (build 7100)

    explorer not working for me too…
    fixed by putting back the old dll’s in safe mode, but no custom styles for me it seems

  5. Random User says

    Didn’t work, left windows in a mess, had to system restore. Not much fun. =[

  6. Backfire3788 says
