Just wanna share a weirdness happened to one of my PC. I previously have Windows 7 ultimate installed prior to installing WDP. Accidentally (don't know) WDP just lettered my System reserved drive and exposed it. When I started win 7, it was just able to locate it, what a weird? I leave it as it is because I'm afraid any modification will cause unexpected things happen to win 7. Is it an example that win 7 can run with lettered System reserved drive?
Here is the screenshot.
