Must admit I had what seemed rather strange to me a few weeks ago when doing a fresh install of XP Home.
I'd just bought an Acer netbook (with XP Home) and didn't want all the other garbage that came preinstalled. Rather then try and uninstall the masses of unwanted software and have untold follow-on issues, I decided to reinstall XP Home from scratch (using an existing XP Home CD as a source and the Product Key of the netbook).
For some reason, although System Restore was there (or at least it seemed to be) with an entry in System Tools and a tab on the System Properties dialogue, it was turned-off (in the afore-mentioned System Properties).
I didn't investigate further as I only discovered it was already off when I went to turn it off (I don't use it - much prefer to rely on Acronis TI).
Thinking about it, makes me wonder if this sort of thing might be to do with hardware / BIOS conflicts and somehow not being deemed compatible with System Restore.
