The computer that I typically use at my house is almost always expressly used by myself for business purposes. My children have their own computer that they use in another room in the home, but this one evening they did not want to go into the other room so I decided to allow them to use my computer for a change. After all, how much harm could they possibly do in a single hour that they would be working on my computer?
If you are having trouble with your PC, as it is working slower; then you must download registry clean programs to retrieve its normal functions.
