Not sure if this was posted ... but I didn't see anything that appeared to be the same. I used 1.1.6 b2 with Ultimate x64 and slipped SP1 before installing it on my laptop. I only removed languages and printer drivers ... other unneeded drivers too. And UAC! I would have pulled more, but I wanted to run a diagnostic and see how each piece would effect system resources. I went into the remove programs and features and opened the list. When I click 'OK', it sits for a little while before giving me an error stating "An error has occurred. Not all of the features were successfully changed." This kicks my RAM usage from ~ 500MB up to around 750MB for about a minute, then it slowly drops back down to 600MB. But not all the way. Further, some of the items I selected (Tablet PC for example) continue to run. I've turned these features off and on a million times prior to vLite'ing the program, so I know how they work ... and they normally do. Not sure how to fix, but wanted to post my observation so that someone that does can pass it along to those that can fix it. ** I am going to reinstall a different (slimmer) version tomorrow after I change out my RAM. I had installed the other package yesterday and just wanted to get a base measure for performance diff. I had Tablet PC loaded in that one, and was able to turn it off. ** Note that I have an HP tx1000 laptop / Tablet. At any rate, I love vLite and will continue to fiddle around till I get the best mix for my needs. I just wanted to share.
