I was using windows 7 which worked fine for me but after the announcement of windows 8, I was very excited to use it. Certainly I came across a Windows 8 metro skin so downloaded and installed it. First time it worked like a charm but after that my computer got damaged and started hanging too much so I tried to uninstall it but I am not able to uninstall it now. Is there any way to resolve this issue without Formatting the system?
