While without fail Windows XP may have been the most popular version of Windows ever, it did remove the OS/2 subsystem, something I had grown used to having around.
But without fail the MS-DOS and DPMI environments were still in place.
Windows XP of course also entered the home market with the aptly named Windows XP Home edition, which was limited to a single processor and couldn’t join any domains. For the sake of my upgrade path, the ‘workstation’ versions became PRO with Windows 2000 & XP, so that is what I’ve upgraded to is XP Pro, without the slipstreamed SP1/2/3.
Unfortuanatly right now this is the end of the road, XP doesn’t upgrade correctly from Windows 2000 and it leaves me with a black screen at best, or a BSOD related to Bug Check 0x19: BAD_POOL_HEADER … Error code was 20 so … there you go.
