Fresh Win 7 Install on 240gb SSD-52gb free space missing-where?

[wbearr]

Did a fresh Win 7 install on a new unused Intel 520 240gb SSD. During the install windows showed 223gb unallocated. I hit next as usual and completed the install.

Have not installed anything else yet. Explorer properties shows 223gb capacity, 63gb used and 159gb free. All the windows stuff takes up approx 11gb.
63gb minus 11gb = 52gb used up but where? There is nothing else I installed or can see.

Disk management shows the normal 2 partitions. System restore 100mb and the 223gb C: partition with 159gb free.

I have done several installs with this drive on laptops and desktops and have never seen this. Can anyone help??? Thanks

Edit: Ok forgot about how much space 32gb of ram takes up before changes are made. Duh!

Re: Fresh Win 7 Install on 240gb SSD-52gb free space missing-where?

your pagefile (reserved ssd space for memory) will also be 32gb (don't disable it!! just reduce its size)

you can reduce it to around 2.5gb and save some space,as will disabling s3 sleep(around 5 to 8gb)
