I have trouble with the simplest operation of my PC. I need to know how to temporarily disable and restart my virus protection program and others; I need to know the routine to completely uninstall a program; I need to know how to defragment my files on hard disk, etc. I need to know how to handle CDs and DVDs, copying to and from, and burning. I need to learn these simplest procedures. Can someone please send me these routines or tell me a good source?
