I don't think it will save much room to jettison language packs and amd drivers. how big can they be?
I would search for big files; pdfs, CABs, and sound files. but I suspect there is some major space hog - the system restore option would be a prime suspect. Myself, my restore strategy is to have data backed up, and just reload windows.
Here we are, back where I was with my first 386 (25mhz)-- with a 40mb hard drive. I learned a lot about Windows 3.1 by deleting help files, backgrounds, and fonts. Those were the good ol' days.
This yr, I build a comp with an ssd for OS, a hdd for storage, and a CF card plugged into the IDE connection (CF to IDE adapter)for pagefile. Things have been working fine for the several months of its life. That is a cheap way to keep swap file off of both the ssd and the hdd. I had the CF card lying around. You can do this with a fast SD card for not much money: the adapter is from Syba.
The only prob with that computer was na ssd power connection that kept coming loose - I was sure it was some tricky ssd quirk, or my CF card swapfile - nope, just a loose power cord.
