Basic XP (SP2) with IE/OE 6.0 (OEM install early 2006)
Very minimal stuff runs on system startup.
After 30 second boot-up, almost everything will run right away, including web browsing with IE.
About one month ago OE started waiting about 2 minutes after boot-up to start. (If you wait 2 min. after boot, OE starts instantly after clicking its icon. Click OE icon right after boot, OE won't open until after symptom (1) described below has occurred:
1) For 2 minutes after boot-up essentially no HD activity, then a few second burst of activity.
2) Same 2-minute delay ending in 2-sec HD burst under Safe-Mode-with Networking boot to complete
3) No delay under Safe-Mode-without-Networking boot
