Windows 7 Ultimate install uses 80GB

[Skyehawk]

Hello,

          I recently upgraded to an SSD and added some more RAM to my PC. I bought a 128GB SSD (Samsung 840 Pro) and 16GB of additional RAM (For a total of 32GB [video editing]). When I installed Windows 7 Ultimate (same price as pro at the time) the final file size, before I added any files, drivers, utilities, or programs was about 80GB. I installed the same copy of Windows again to see if the file size shrank, it didn't. I know this size is about 6-8 times too large for the actual install size of Windows 7 Ultimate. This size is a problem on a 128GB SSD (most of my files and programs are installed on an additional HDD.) When I add up all of the files on the SSD (including hidden) it adds up to (about) 16GB; as opposed to the properties where it says 80GB.

 

          In regard to my settings and such: I am not using any form of hibernation;

                                                                 I am completely formatting the SSD and removing partitions before I re-install windows;

                                                                 I am installing windows off of a non-retail copy disk (ISO file burned to disk, it seems to work fine.);

                                                                 Windows installs in about 45min-60min.

 

          In a nutshell: The windows install is much larger than it should be.

 

          Any help would be much appreciated.

 

          Best Regards,

          Skyehawk

since you have 16GB ram then the hibernation file should be quite large. If you turn off hibernation, make the page file smaller and then run CCleaner or windows disk cleaner tools then you should see a considerable amount of storage freed up. 80GB is excessive though. use spacesniffer to see where the files are that are the biggest.

that is really really strange.... I have never seen that before so I don't have an answer but I have a link to a similar problem http://www.tomshardware.com/forum/284299-32-windows-ultimate-install-huge hope it helps.

Pagefile sits on c:\ hidden at first.......defaults to your ramsize right..?

I know Hibernation is there by default, I always get rid of that.

Win7 ultimate takes up 31.0GB on my computer... (Well the Windows folder which is almost everything that is written when you install). Can you download SpaceSniffer and take a look at what's using up the most space. Upload a screenshot to imgur or similar and embed it in the forum.

Just an update... Here is what I get when I run Space Sniffer.

The pagefile.sys(31.8GB) & the HibererFile.sys(23.9GB) are the largest.

                                                      ^this is the hibernation files... but that still leaves my windows install at around 50GB...

CMD prompt with admin rights

powercfg -h off

Turns hibernation off, although you can download "tweaking" programs to remove it also...

Resizing the pagefile is easy, tell windows NOT to manage it, set min/max accordingly to 256mb/4096mb

[colonel_mortis]

You need to disable page file. Start -> Right click on computer -> Properties -> Advanced system settings (Left pane) -> Advanced -> Performance Settings -> advanced -> Virtual Memory change.

Set it to at least the size of your ram for dump files, or as small as you like if you're not going to make memory dumps. (Mine's on 1GB).

Restart your PC

Ooh, seeing all that space is beautiful. Thank you guys for all of your help.

80GB - 31.8GB - 23.9GB = 50GB? Can you even math? :P

I was referring to the largest file.
