I have a folder named 8b063dfa935bea035ce5eaca in My Computer and i cannot see any files inside even though i have full administrative permissions. Should i be worried this is some malevolent file?

Try to pair the creation time & date with Windows Update log time & date. Chances are that this is a remnant from update process. You would not do a mistake if you check thouroughly your W 7 with updated antivirus/antimalware program Regards Milos
