Last weekend my friend come to my house and bring his new laptop with new problem. All programs cannot be opened because registry is corrupted. I try to open any program, includes mozilla, yahoo messenger,cmd and regedit, but this crappy windows 7 always redirect to open Windows Media Center. All programs' icon turn to windows media center. I try to ask google and it is actually a virus. What we need is repair the registry that fooling windows user.
The solution is:
download this registry file HERE, and double click on it.
or copy paste these two lines into a file and save it file.reg. Then, double click it.
Windows Registry Editor Version 5.00
Then reboot to restore your icon as normal.
Hopefully this will help u :)
