Windows 7: Is Windows 7 tweaking itself?

after i installed build 7264 x64 as an upgrade to 7229 i found this:
-in the first days, my system used about 1,8 gb of ram, now it is at 1,4 gb without having changed something
- the system responds faster after some days
- it seems to have tweaked and optimized itself during the last few days
after the upgrade i had tried the usual optimizations as defragmentation, cleaning unused files from the upgrade and so on.
did anybody else find something like that?
i find this a great feature!

Yep, it rocks.

Web search on "Windows 7 prefetch" for more info.


Edit: nvrmnd - HERE you go

I usually find that after the first couple of days it seems to speed up and becomes more responsive, I think it has allot to do with indexing.

You're onto something there. When not running the 32bit RC for a period of time constantly booting into the 64bit the power options settings tend to forget themselves where each startup means setting the turn off display to never over and over again. On the host 64bit RC booted into daily that problem simply "vanished" from regular use!

The file indexing would seem to better organize the system's own access to regularly used files like those for Windows itself. The SuperFetch in Vista preceeded by the PreFetch in XP has been improved in 7. That preloads the drive maintainence tools in low key to run in the background keeping the fragmentation level down as well to 0%! Self maintaining OS to some degree.

I would caution against removing superfetch in windows 7. I looks to be more closely integrated than in previous versions.

I am worried about my SSD. Superfetch is off. I hope if I have problems I can just turn it on again. With an SSD my system is very responsive but they have problems as we all know. I hope it's different with this bunch.

You should read this info....HERE!

I have read this and many more like it. I assume you have to run WEI before Windows makes these changes because I didn't see them made. I had to turn them off myself. This is with the RC. Maybe things will be different with RTM. I wish it would let you know. "Windows knows you have an SSD and it is making the correct changes" That would be nice.

Thanks for the link.

Nothing here say to remove superfetch.
The link show the opposite: keep Superfetch ON!



The system (via superfetch and other mecanism) can adapt itself to your usage.
When you use your computer the system analyse what you done, which software you use, when you use them.
Superfetch is able to make the difference between software most used on the week and those used on the Week-end, in example.

So dont worry, the memory usage is totally dynamic and will vary all over the time

I actually turn the indexing service off, as I hardly ever use the search function. I just wish I could turn off that "Your searches would be faster ..." banner the few times I do a search in Win Explorer .
