I decided I missed all the great old skins of the past
Me too, but I didn't decide so. A few weeks ago I had a major mishap with my PC and lost them all... every single WB, IP, CXP and every Winstep theme... all my stored skins. It shouldn't have happened but Acronis True Image reformatted my backup drive and began to install a system backup on it. The backup image was supposed to have been restored to my OS drive, a SSD, but that's not what happened and I lost 300 gigs of data. Acronis say they have never heard of such a thing and essentially dismissed it... which to me was no better than calling me a liar, but I swear it happened and I'm not happy my case was not taken seriously enough.
I did perform a recovery operation with a couple of undelete type programs but only a handful of recovered items were viable, thus leaving me to re-collect those skins I loved the most. Worse still, I lost hundreds of photos and documents as well. Fortunately, my sister has most of the photos so not all is lost there.
Anyway, to cut a long story short, I am refurbishing a PC to put XP on, not just for the purpose of using those fav old skins, though it's a prime motivator. Another reason is to have a setup to play some of the older games that do not play so well on Win 7 or 8. We have a Myst boxset that isn't comfortable on latter OSes, so XP is it. I will have it all updated with the 3 service packs, but it will not be connected to the net so I'll not worry about internet security or anti-spyware packages.
