Running Vista Ultimate 32 bit SP1 on Dell XPS M1530 notebook Since purchasing ESS I have had continued problems with it killing the the loading of the desktop. Every time I get a new MS security update, after login, the desktop will not load, I would just get a blank screen. If I reboot into Safe mode and kill the ESS service, it loads fine AND ESS loads fine manually at that point. I tried disabling all Non-MS services and startup items to no avail so there seems to be a conflict with a MS service- and I'm not going there. In the past reinstalling ESS would cure this problem. After the most recent MS updates though, reinstalling ESS did not help and I could not get ESS to load normally. After much trial and error, I changed the ESS service 'ekrn.exe' to 'Delayed Start' and the desktop now loads normally with ESS loading last. Does loading last compromise the ESS anti-virus protection?
