i dont like the fact, that win7 constantly uses above 30% MB RAM in idle (in my case it was 450 to 500 MB), even when i disabled superfetch and indexing, nothing changed the eating of it i used 5 different "memory recovers" from which, 1 i know is quality since i used it even in days of win98 and memory eating even went higher after trying to recover RAM i don't wish to go into endless debate: empty ram VS full ram usage is better but fact stays if both vista and 7 were not so heavy for god knows what reason... it wouldn't need pre-caching nor such hogging same goes for DWM, it supposedly uses GPU but look the miracle, when i had whole full glass enabled on RTM versions (both Home prem and Ultimate), DWM jumped from 10 to 20% of CPU usage i mean cmon ! - i know emulators of glass (with blur) that were made for XP and they use 1 to 3 % of CPU and THEY dont have their own Composition Engine ! what about SxS ?, this bullcrap service or call it whatever you want... should HAVE backed up ONLY system files, and NOT of every little app that is installed i agree that win7 is nice and more secure, but it is certanly NOT a step forward. the bad image of Vista allowed them to continue with same approach but only changed appearance and there you go, its not 30% fat milk in white box but 25% fat milk in white box with blue stripes the excuse RAM is cheap, OS should use FULL power of newest Hardware parts does NOT approve the way how they made OS work and use it i think most of you would agree that OS requirement/its usage should be minimum and rest left for Apps to use
