You actually can uninstall with the Windows uninstaller, but you have to dig down one more level. Right-click on Start>Apps and Features. On that window, look near the upper right corner for Related Settings and underneath that, click Programs and Features. Let that window load up(5-8 seconds), find Avid Pro Tools, right-click and select Change. That will allow you to uninstall PT. In the next window, you may be presented with 3 options of:
Pro Tools only
Pro Tools and HD driver
Pro Tools.....(basically everything)
In your case, I would check the 3rd option for a "complete" uninstall. Fingers crossed for ya
