Hi Mahmud, as the issue can be caused by corrupted user profile or virus infection, I suggest you first perform the following steps to troubleshoot the issue. Control Panel -> User Accounts -> Manage User Accounts. Please create a new account and log onto it to check the result. Does the issue also occur in the new account? If so, I recommend performing a virus scan on your computer. You can try a free online virus scan on the following site: http://safety.live.com Meanwhile, if you need more help with virus-related issues, please contact Microsoft Product Support Services. For support within the United States and Canada, call toll-free (866) PCSAFETY (727-2338).
