I am starting to think about W8-1 as about pretty unstable system. I did W8-1 installations on three different computers last week at each one there is different error and all of them are (according me) annoying: 1. After I added drive C:\ location (as root and subdirs) for indexing, SearchIndexer crashes (almost) at every boot. I tried to delete and recreate index but no luck. 2. New SkyDrive tray icon sometimes doesn't start and in that case there is also no SkyDrive option in File Explorer left panel. Tray icon has to be manually invoked by starting METRO (!) SkyDrive application. 8/ 3. System reliability graph just shows nothing for three days. I tried to reset it, but again no luck. I hope, that W8-1-1 will be more stable. :/ Did you get stable W8-1 without ANY problems after your clean installation?
