One reason, Windows XP Home cannot be an RDC server so you can't log into it using RDC from a remote client.
Why not just download it? The only advantage that a paid license gives you is unrestricted access in batch mode, otherwise the versions (unlicensed vs. licensed) supposedly operate the same.
Not really everything, but a decent sample of some of my absolute favorites (in addition to everything in my sig) Teracopy -- makes Windows copy not suck so much Irfanview -- a general purpose image viewer that just flat out rocks. It's not a photo organization program, or a powerful image editor -- it mostly just displays images, and it does it better than any other program I've found. UTorrent -- my favorite torrent program Launchy -- THE best program of its kind -- allows you to start programs by typing their name Notepad++ -- My favorite free text editor by far. I used to be big on SciTE, but Notepad++ is far superior. IMGBurn -- Fantastic burning program Foxit Reader -- PDF Reader for Windows. Like, a million times better than Adobe's in almost every way -- starts fast, doesn't eat resources, works great. 7-Zip -- Great compression program that handles most formats PDF Creator -- Open Source PDF Distiller VLC - Pretty decent media player that doesn't require codecs. I usually do K-Lite, but VLC works for most everything. Filezilla -- Great FTP program. Unless something has changed, the newest version (found here) doesn't allow proxies. I use the old version (version 2) and it works great for me. Folding at Home -- Put your computer's spare processing to good use.
