Whenever I do a clean install of windows, it comes around 140GB!!!
I have 128GB of RAM, and I have 2 i7s, and My Motherboard is the MSi BigBang Xpower 2. I created a special thing for it so it uses 2 cpus, and i'm REALLY not liking thing being taken up on my 200GB drive.

I'm not sure how you could have so much ram and 2 cpus on that motherboard...

But assuming that is correct, your space issues may be related to the page file. When a large amount of RAM is installed, widows automatically creates an unnecesarily large page file, which takes up space on the boot drive. You can manually decrease its size by going:
Control Panel> System> Advanced System Settings> Advanced tab> Performance (settings)> Advanced> Virtual Memory (change...)

Untick automatically manage paging file size, and select custom size. enter an initial size of 4000mb and a maximum size of 16000mb.

That should reduce the size of the windows install back down to 20-30gb.

ahh, hiberfile.sys may also be taking up a lot of room. But I think with that much ram the page file could also be obscenely large.

to disable hiberfile.sys (keep in mind you won't be able to hibernate if you disable it), open up command prompt by right clicking the command prompt icon and selecting "run as admin", type:

powercfg.exe -h off

and press enter.

I thought page file allocated 100% of the amount of RAM installed by default? I may be wrong though. I have 16GB installed and it automatically allocates a 16GB paging file.
 

Assume that it is not correct. 128GB would require unbuffered 16GB sticks and they are not available so far. Beside that the 7i doesn't support dual cpu setup, not on this or any other mobo, because of the missing interconnects.

it's also only got one socket on the mobo.

I too am having space problems with win 7, i set up the C: partition with 30gig because msoft said win 7 will need 20 gig.
There has been no data saved to C: except for win 7 updates. When i first installed win 7 it grabbed 20 gig and another 5 after i had registered the OS, since then it has consumed a total of 27.5 gig. To put it another way last night when powered down there was 2.71 gig of space left on C:, this morning when i powered up there was 2.38 gig! where the hell has 300mb gone over night
I have gone through the usual tips to save space bit it only recovers so much, i have not got a swap file set on C: because when i installed win 7 it took so much space that there was not enough left for the swap file, ( i have 8 gig of ram ) win 7 then grabbed all of my programs partition 10 gig which i then swithched off and set back up on the data partition 185 gig - win 7 grabbed 10 gig.
The pc runs fine but the blue line that shows how much space is left has turned red, i had this problem with XP and used partition magic 5 times to resize C: but it causes some problems itself.
I have read your thread suggesting how to switch of the hiberfile but when i try to do this command prompt says that it is not an internal or external command? I am not profficient with command prompt and think i may be making a mistake somewhere.
Any advice regarding this would be welcome.
