About a week ago, after a clean installation of Windows 7 Ultimate SP1 x64, I installed the usual software (Adobe Flash, Java, VLC, Firefox), but decided I would take my chances with Transmission-QT over the familiar qBittorrent after using it on my Linux Mint partition for a solid month without a problem. I left to visit my mother for a few days, and when I returned, my webcam light was on. I unplugged it and installed the windows updates that I had forgotten to install beforehand, and then I rebooted. I plugged the webcam back in, and it turned on again. I unplugged it, and it's been off ever since. Until today, I decided I would try out my USB microscope, so I downloaded the software from the manufacturer website, and the software isn't detecting the microscope, even though the light is on.
I did a virus scan in safemode with networking using malwarebytes and I didn't find anything. I tried looking to see if the camera was being accessed using TCPView and ProcessExplorer, but I couldn't find my device. People have recommended I just format, but then I won't be able to access my linux partition without repairing the bootloader, which I'm bad at.
