My parents laptop has now got 77 notebook looking files with various names like this which through googling i have found out to be something to do with the windows security updates but what i wanted to know is can i delete them as my the laptop is getting sooooooo slow i am getting to desperate measures to free up some space! Does anyone know? I think they are only log files aren't they?! Do i need to keep them for any reason ? Will be super greatful for advice Thanks Amy-x-
