Too many questions all at one, my head hurts......:hammer:
So, I'll try to answer your last question.... Backwards comp. of games can be hit or miss, unless you have WHDLoad (Google it) I highly recommend getting and registering WHDLoad, pretty much any game/demo, new or old , will work, assuming your miggy has enough RAM, etc...... YMMV, or course.
As for apps., the vast majority are system-friendly. You may find an older app that doesn't like a certain program, or in my case, hack..... Both MakePath and TerraForm (??) add-ons for Vista won't work properly if Magic Menu is running?... :confused:
You can always try programs like Degrader, etc. to help with comp. ....
