Windows Experience Index in Windows 8.1

Microsoft removed the Windows Experience Index tool from Windows 8.1. Although, probably not many people use it, it was still a very easy way of benchmarking a PC without using 3rd party applications.

Luckily, the feature is not completely removed from the OS, it's just a not exposed on the user interface.

To create a benchmark, just follow the next steps:

  1. Delete all XML files in C:\Windows\Performance\WinSAT\DataStore.
  2. Open an elevated command line (run cmd.exe as an administrator) and type: winsat formal -restart
  3. After the assessment the results can be found in C:\Windows\Performance\WinSAT\DataStore.
    <DATE and TIME> Formal.Assessment (Initial).WinSAT.xml will give you a nice overview of the results:

Windows 8 does not Recognize Some DVD Drives

In some cases, Windows 8 doesn't recognize CD and DVD drives even if the installation was performed from that drive. It doesn't even appear in Device Manager.

To fix this issue a quick workaround is needed.
  1. Open a command prompt as an administrator.
  2. Issue the following command:
    reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001
  3. Reboot the computer
After the system is back on its feet, the DVD drive should be recognized and usable again.
