Clean Win7 Pro install taking 90Gb, with 48Gb pagefile!?!?!

Hello,

I just did a fresh install from DVD of Win7 Pro on my new Solid State Drive. The drive was brand new, empty. 256Gb drive.

Once the install was done, Windows 7 is taking up 90Gb on the SSD! So I checked - the pagefile is set to 48Gb, the Windows folder itself is 30Gb, and then there's 12Gb still unaccounted for.

Now - I have 48Gb of ram (yes, fourty eight gigabytes). So I'm guessing Windows just blindly sets pagefile size equal to installed ram?

I've seen many threads saying to just go ahead and reduce pagefile to something like 1Gb - but, is there a good reason Windows does this? Maybe a valid reason to leave it this way? But if not, I'd rather recuperate the 48Gig.

Thanks

pagefile and hiberfil.sys.

Turn off hibernation, and reduce the pagefile to 1024MB max and min. Some people remove it completely. but a few applications may balk at not having it.

You will not see any performance difference in having a very small pagefile.
I have 16GB RAM, and set the pagefile to the above. Zero performance issues.

You know, I had turned off hibernation via gui - but your post made me question it - so I did some more searching and it seems the gui is not effective at really turning it off - you have to use a cmd command. SEt Windows Explorer to show hidden files, and there was a30Gb hibern file. Turned it off via cmd, and the file disappeared immediately.

And ya - took the general advice and turned pagefile way down. Windows is now just 12Gb on my SSD. Perfect, Thanks.
