c:\windows\system32\winsat.exe RRS feed

  • Question

  • Within the past week when I have started my computer and typed in my password, the system seems to freeze momentarily and then a window pops open running C:\windows\system32\winsat.exe.  This lasts for over a minute and proceeds to the desktop.  This has happened twice.  Some of the testing in the window involves Direct X and then it starts checking items with encryption.  I've already had to do a system reinstall once this year.  Any suggestions?

  • WINSAT.EXE is the executable file name for Windows Assessment tool.
    For some reason, the program is performing some tests on the system to evaluate the Windows Experience Index, but I cannot understand why it's running after the system boot.
    You could use Autoruns (http://technet.microsoft.com/it-it/sysinternals/bb963902) to see if there's something configured to run automatically at the system startup that could be related to that program and Process Explorer (http://technet.microsoft.com/it-it/sysinternals/bb896653) to see if the program is still running after the boot; you could also use Process Monitor (http://technet.microsoft.com/it-it/sysinternals/bb896645) to perform a real time control over the activity of any process in the system (included this one).
    Also take a look in the Windows logs under the Event viewer to see if there's any kind of record related to this program.
