I am having Windows 7 Home basic in my system. From last few days I am not able to run shortcut commands from the Start Command Prompt( that can be opened by clicking the windows icon on the left hand bottom corner of the system'S taskbar) to open a file or application ( like winword , excel , textpad, notepad , explorer etc...anything ) . When I type the command shortcut in the space , the window that opens along with the prompt just says searching for few secs and finally stops with blank ( no result ). I tried running antivirus , malware, spamware nothing worked. I also tried system restore but it also fails to resolved the issue. May be corrupt registry issue ( just a guess) but do not know how to fix this ?? Please help .
