The problem is that in evaluation copy of Windows Vista RTM final release, a watermark message will display on the right corner of the deskto:

Windows Vista (TM)
Evaluation Copy. Build 6000

Other than the evaluation watermark, you may also have a “Test Mode” testmode watermark showing on your desktop, if you’re using unsigned driver running in testsigning mode, especially in Windows Vista 64-bit edition.

The watermark about Windows Vista evaluation on the right corner of desktop is set by user32.dll.mui file located in \Windows\System32\en-US\ folder (last folder depending on which language option Windows Vista is installed, in the form of xy-XY, such as for German, it’s ‘de-DE’ folder). To disable, remove or get rid of the evaluation watermark in Windows Vista, simply modify or mod the user32.dll.mui file accordingly.

  1. Download and install Resource Tuner or PE Explorer or Resource Hacker that allows users to view, modify, rename, add, delete and extract resources in Windows executables and resource files (*.res).
  2. Navigate to \Windows\System32\en-US’ folder, and right-click on user32.dll.mui, and then click on Properties on the right click contextual menu. Then, select the Security tab.
  3. Click on the Advanced button, and the click on the Owner tab.
  4. Change the settings and edit to take ownership of user32.dll.mui file. Click OK when done.
  5. Go back to the Advanced Security Settings again, at Permissions tab, edit the permission that assigned to yourself to Full Control to get full access to user32.dll.mui file.
  6. Make a backup copy of user32.dll.mui located in \Windows\System32\en-US\ folder.
  7. Run ResourceTuner (or PEExplorer or ResourceHacker or others) and navigate and open the \Windows\System32\en-US\user32.dll.mui file.
  8. In the left tree-view pane, expand ‘String’, then click and open Item #45 and modify a few lines of strings so that the final results will look likes in the image below.Vista evaluation hack

  3. Go to \Windows\System32\en-US\ (normally c:\Windows\System32\en-US\ file location).
  4. Make a backup of user32.dll.mui file or simply rename the file to another name such as user32.dll.mui.bck.
  5. Copy the patched user32.dll.mui to \Windows\System32\en-US\ folder.
  6. Restart the computer.
