So I have been using windows 10 and have troubles with using the integrated webcam for my Dell Studio 1558 Laptop. The camera would just stop working and I learned how to fix it.
For the fix, go to the device manager and see if the integrated webcam is listed under imaging devices. For my case it was not listed there, however I could see a couple of "Other Devices" and an ambiguous looking device under "Universal Serial Bus Controllers". What I did is to uninstall ALL devices listed under these categories one by one and restarted the computer. The camera worked fine after that!
Good luck!
