Reformating Computer...

Once again I am reformating my computer.My Microsoft Word just cannot function as normal even though I uninstall and re-install how many times.And more over,my antivirus and NJStar have expired.I tried to find out how to crack the 2 software before I did the reformat but in vain.I was watching VCD House Of Wax while doing the reformat so no time wasting.
After watched finished the VCD,I reinstall all the software which I was using except for the ICQ 5(Lite) as it slow down my computer,I also don't know for what reason.Trying to solve the expiry problem but I can do nothing.When I was installing the Microsoft Office,I found a problem.I lost the CD numbers.Luckly I did lots of installations previously so I can somehow remember all the letters.I need no to look for the cd case for the number.Can you believe it,I can memorise the letter with no mistake?
