I think its solved but doing an online virus check just to be sure!
If explore.exe doesnt work [for me it flickered] go to regedit.exe and follow the pathway
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
\StuckRects
delete StuckRects then reboot and hopefully problem solved [i hope]
Ok everyone this didnt work! I did a combination of things to sort this as i have seen this problem has plagued a lot of people! Oh this SHOULD work then after make a restore point, just like i have!
Press control alt delete select run and enter explorer.exe! The tricky party is double clicking internet explorer to open it. Once this is done google RegistryFix and get the latest version, and get a crack along with it. Let it does its job and it will fix all ur registry problems! Also just to make it safe do a virus check immediately after and i used Advanced WindowsCare V2 Pro to fix any additional bugs then restart! hey presto it should work!!!
