Windows XP SP 3, ESET 5.0.93: This morning, ESET flashed the "!" icon and indicated that the operating system did not have all the updates applied. When I manually ran Windows Update, there were 3 .NET high priority updates and no critical updates available. I downloaded and installed the 3 updates and then checked the setting under Tools/System Updates in Advanced Setup, which was set to "Critical" 1. Does ESET lump high-priority updates in with critical when checking? 2. Why do the classifications under Tools/System Updates not match what Microsoft classifies under Windows update?
