Yep, tried this myself and it didn't work; in fact it did more damage than good. I get different error almost nearly all the time when I try to install an app from the store. It was even impossible to reinstall old apps when you uninstall them after using
the procedure above.
It was so annoying that I just went ahead and restore my tablet back to the factory settings. Until Microsoft decides to start listening to us, its consumers, I might be saying goodbye to Windows 8 soon. As much as I really want this to work (it's my portability
dream), it's not looking good for Windows 8; might have to go the Android route (besides, most of the apps I need, are available on Android's Playstore). Just going to miss the fully functionality of a PC at my fingertips -- as you probably can tell I do not
fancy the idea of lugging a laptop/Netbook (even if it's a "10" or 11") all over. Oh well...
