My CPU hovers around 50%. In the Processes tab, "Private" memory for PkgMgr is fixed at 900KB. In the Performance tab, physical memory is fixed absolutely flat at 707MB. (I have 2GB total.) I find it suspicious that memory usage should be fixed. I would expect some variation. I've made some "negative" progress I can integrate some hotfixes. But I still can't integrate SP1 I integrated the smallest hotfix (KB947821, 28KB). So that was the first time I saw the "Finished" message. This job took 2 minutes. However, only the "Finish" and "Exit" buttons were available. Does mean that I could not have burnt the ISO? I then integrated the largest hotfix (KB955020, 57,618KB). This job took 11 minutes. In this case, when the "Finished" message was displayed, only the "Exit" button was available. BTW1: I know that hotfixes without SP1 is probably no good to anyone, but I wanted to see what was possible and what was not possible. BTW2: I'm currently trying VLite 1.1.6. The following post by steven4554 suggested it might be less buggy: http://www.msfn.org/board/index.php?showtopic=133061 .
