So you missed the windows 10 upgrade

Note: Actually, I use a band-aid over the lens because if I ever find a use for the cam, I won't have to clean sticky gunk off the lens, because the pad part of the band-aid goes over the lens instead of the sticky part.

That is where WD-40 comes in handy!
Great at removing the unwanted sticky gunk off webcam lens when we remove our protective force shield.

I found that Alcohol works good for sticky stuff and then when the lens is clean,,, I show them what to expect if they're Brave Enough!
