Hi Larry: I didn't actually upgrade my computer from Win98 to WinXPhome, but instead, purchased a 'new' computer with XP Home pre-installed, keeping my older computer with Win98 as well.
I'm successfully running XP home, all my regular apps (Photoshop, Easy CD Creator, etc) as well as music programs (Cakewalk Sonar XL, SoundForge, EMC StyleWorks Universal, Band in A Box, Yamaha PSR: StyleEdit, CasMEdit) and experiencing no problems whatsoevever. In fact, everything appears to be running FASTER and ROCK SOLID (no crashes, freeezes, or hangups). The only music programs I can't run on XP is a 3rd party Technics KN5000 hard drive backup program (TechMgr5000) and Yamaha XGWorks, which I hear will be updated soon to run on XP. I highly recommend XP (home or Professional) to everyone for music production. You will need to have at least 128 mg RAM to run it though (unfortunately the XP is a memory HOG). I recommend 256 or MORE - memory's cheap now anyway. I myself went for 512 and glad I did. You will see a marked speed increase especially in audio work, and the the new WDM (windows media drivers) have real LOW latency.
Being a longtime Mac devotee using Logic Audio, I was previously rather skeptical of even considering the PC for serious professional music production, but With Windows XP and the latest version of Cakewalk Sonar XL, the PC has finally matched the MAC, even for professional top studio quality music production (and at a much cheaper price to boot).
