I have an old Dell Laptop that is a Pentium III 500 mhz with 256 MB of ram.. Running Windows XP Service Pack 3. Install process went smooth, and it's running good so far. At work I have the Tier 2 Technicians running it on their machines keeping me informed of any issues.. I however did run into one issue where after post install ekrn.exe hogged the CPU for about 3-4 minutes, and NOD32 never loaded in the system tray. However upon rebooting after the disk thrashing everything started up fine. Initial ram usage was up in the 30s-50s and has now dropped down to 22MB for ekrn.exe and around a 1Meg for egui.. No sysinspector bug so far like another user has posted. I had some of the guys at their own time try it out, and get familiar with, and add/remove snapshots nobody reported that bug.
