HP Pavilion dm1 Webcam Not Working After OS Change

After changing the operating system from 64-bit Windows Home Premium to 32-bit Windows 7 Professional, the internal webcam would not work. The HP MediaSmart Webcam software or Skype would give a error message saying:

HP MediaSmart Webcam cannot connect to your webcam (HP Webcam-50).
Skype can't connect to your webcam.

The drivers for the webcam were installed from HP's website and the Device Manager showed the webcam as working.

I found this info:

1. Open regedit
2. Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000
(This should be the registry key for your webcam. If it is not, it may be at 0002, or 0003, etc.)
3. Add a new 32-bit DWORD value called "UvcFlags"
4. Set the data for this value to 10 (10 Hex, 16 Decimal)
5. Restart your computer and test the webcam


There was also a 32-bit DWORD called "KS" with a value of 1 on the original 64-bit Windows Home Premium installation.

After adding UvcFlags & KS and restarting, the webcam works fine now.

I have a 2nd HP Pavilion dm1 that I did the same OS change to & it had no issues with the webcam.
