Close button is not working in Windows7
I am using Dell Inspiron 14 with Windows 7 pre-installed in it.
It was working great, but after a few months, recently I started getting some issue may be because of the system slowness. When I click the close button on any open window, it is not closing the window. I thought this was due to Virus and did full System scans using MBAM Pro, McA Fee and Avast Antivirus.
I am not able to figure out what is causing this issue. Any more ideas? Please assist me in this regard. Thanks a lot in advance.
