how reduce the size of used space in windows. i do not want to compress fiiles becouse i already did.

You could google "slimming down XP guide" or (my preferred method) use nlite to remove components before they get installed.
And you shouldn't really compress files because it will cause a performance slowdown.

Or you could even search these forums: http://www.neowin.net/forum/index.php?show...t=0&start=0

Why though?

HDD is aplenty.

unless your on a 20gb HDD or something

Delete Windows Update files after they have been installed, disable hibernate, decrease page file size(not recommended), compress files(not recommended), disable system restore, clean temp folders.

nlite

XP slimming guide +1

works for vista too

I only have a 50 GB, and 27 gigs are taken.

I have no idea where all that came from
