Tuneup Utilities 2013 smoked my Windows to death! So I was having a weird error everytime I started MPC-HC that there was a problem with the MPC-HC dump file. I tried reinstalling it, updating to a newer version, but no luck. So I thought ok, before going ahead and reverting to one of my old Acronis True Image backups, let me give Tunup Utilities 2013 the benefit of the doubt. I installed the latest version from their site, as soon as the app started, it displayed a message that there is an update. So I click on the update, it downloads some files, then my laptop freezes. Ok, no problem, let's do a forced shut down. Upon starting my Windows the next time, after the progress bar loads, I get an error message in Logonui.exe that says "authuitu.dll" is not a recognized file or something like that. I tried booting into safe mode, and it gave the exact same error message, my system was FUBAR basically. I googled this error and it seems that it is a common error that happens when someone tried to update with no solution. This taught me a lesson the hard way I had to format, reinstall Windows, install Acronis True Image, then restore my old image. For some reason I couldn't restore my previous image using the Acronis Boot Up CD because when I do, the drive letters are all messed up, C: becomes D: and D: is C: as I can tell from the partition contents and attempting to restore seems like it would wipe my D: partition rather than C: so I had to do it the hard way and format then restore from within Windows I cannot believe how such a bad program is so wide spread over the internet and on most reputable sites when it has screwed my system on 2 occasions, one time 4 months ago when I cleaned my systems registry entries, I got crashes all over the place to an extent where the system was not usable. And now this!
