Yesterday my System started to go a little jerky, and i rebooted, as usual, when that happens After Reboot, my Desktop Icons where gone, even tho, all names were displayed properly, and i also was able to click them as usual. Start Button does blink when pressed, but no Menu at all shows up, no matter how often i click it. I already tried several SFC /scannows, chkdsk, scanning for malware with Spybot, which found some, but brought no improvement upon removing them. Finally i tried to replace the msshsq.dll and HotStartUserAgent.dll, both from this Windows itself, and from a secondary windows which worked normally. i did put both files in the windows folder, system32 and syswow64, files were from Here Sadly, i wasnt able to get any improvement Hope you guys know a trick how i can get this to run again, without having to reinstall!
