They probably are then :smile:
Being serious though, we would need a bit more information from you, what operating system, XP, 7, 8, 8.1, 10?
What is the specification of your PC, hard drive size, hard drive free space, memory, processor?
It really makes it impossible to answer your question without you giving us a lot more information to work with.
Sign up to the board so you can reply and try and give as much info as possible, then someone might be able to help you.
