Well, just two general comments about Windows Live One Care.
I am happy that I have not yet installed WLOC on my new Vista Desktop.
I did have it on my older Win XP desktop and Win XP laptop and found that at the most unoportune times, WLOC would bog down my computers, overheating the CPU and adding frustration and delay to getting tasks done that normally would take but a few minutes to accomplish.
As usual, the complicated layers that Microsoft creates when activating products is as frustrating as the performance of WLOC.
Having reinstalled WIN XP on the laptop, with complete formatting, no added applications WLOC took a long time to complete it's tasks.
I would be hard pressed to renew my subscription unless there are significant improvements in the time it takes for WLOC to complete it's tasks.
FWIW
