My dumb brother was doi g something on the computer while I was asleep and now everything opens with windows media center. Im not sure what he was doing, he wont tell us; but im pretty sure he was pirating something. Now every file opens with windows media center, and you need to close it twice. I cant even access the internet or system restore now.
What could be the problem/fix
I could give a picture but not sure how to on my phone
You may have contracted a virus. The first thing a virus tries to do is prevent you from removing it by disabling system restore.
Your best hope is to boot into safe mode by pressing F8 and selecting a restore to a previous good time.
Take a look at control panel/ folder options.
Look at the options and reset to default if you need to.
