it's probably a noob's question, pls don't blame me I upgraded from Home P 34 bits to Home P 64 bits, reinstalled exactly the same progs, put all windows options as before... my OS partition got 8 gigs fatter even after deletion of *.old folders and files any explanation for this ? thks in advance
turn off system restore ,restart then turn it on again .do a cleanup then defrag and look again. not forgetting , 64 bit takes up several GB more than 32bit anyway.
Yes I agree with you but remember that you restore it then may be your latest installed application will be removed and there is not any option to save so you must take this risk.
