Live Messenger & built in webcam

When I use Windows Live Messenger & want to do a video call, it will say
webcam blocked being used by another application. If I reboot I can get the
webcam to work. What other program is using the webcam? Can I disable it so
the webcam works all the time on video calls on Live Messenger?

I had this problem and had to go into device manager and delete the web cam
from there then when i rebooted it reinstalled and i didnt have a problem
after that

This is the built in webcam that is in my Toshiba so not sure ifdelete &
reinstall is possible or would work.

There might be some software installed specifically for the webcam that
is causing the issue. Check the manual on how the camera works on it's
own and see if you can disable the app temporarily to test. Download
Autoruns and uncheck the app that is loading for the camera.

Hey, just to let ya know mine is a built in web cam as well i have an
entertainment laptop brought out by HP. When you delete and reboot it finds
that it is there with no software so it finds the software automatically
within your computer again. Worked perfect for me that all I know

you can always try going back to an older version of Windows Live Messenger it may just be a glitch in the program that they have yet to work out.
