Windows 7: Windows 7 and extra 12 GB upon install

Windows 7 and extra 12 GB upon install

Hi folks,
Tried to search for my problem here but couldn't find anything so here I am.
I installed Windows 7 Ultimate 64bit a couple of months ago on a 64GB SSD. During the first step of the installation, Windows 7 recommended to use extra 12GB (or so) for creating an extra partition to ensure stability of the system. True, half of the SSD space was taken when installation finished successfully. Any idea why this is and do I really need it? SSDs are small and space is running out quickly.
Thanks.

Edit... while I'm at the drive space issue.. Any idea if I really need pagefile ? I have 12 GBram.. pagefile takes another extra 10 GB constantly.

That partition is for repair purposes, but I don't have it. I installed everything in C:. You can delete that partition, but you will have to rely on using the installation disks for any repair needed.

Thanks for the quick response.. I too installed Windows on C:, of course the "partition" that was created is probably hidden since it doesn't appear in Explorer.

I can't be certain, because it has been a while since I had an installation that included the system partition, but I don't remember it being hidden, but then I always have it set to show hidden files and folders, etc. When in Disk Management, do you see it there?

If you want to get rid of the system partition, it will require certain steps. Here is a link that will help:

Removing 100MB system partition - no re-install needed

No, I've already checked DM and the only thing that appears there and not in Explorer is the 100 MB system reserved partition. Something's telling me that these extra GB are actually taken by a hidden image file of some kind, which wouldn't be very wise if the whole FS of the drive collapses and the only solution is to re-format. Anyways. I'll probably just be very careful with updating windows with large files and continue installing every other software on a standard HDD.

About the 100MB partition removal - No need really. 100MB won't help much.. Perhaps I could just either disable the page file or decrease it's size manually if possible as it was on XP. Thanks for the support!

The extra partition that Windows wants to create for stability purposes should have been for 100MB....not 12GB.

Ok, if this is a desktop computer....do you have a standard mechanical hard drive in the system in addition to your SSD? If so, you could put the page file onto this second drive rather than the SSD.

Also, if this is a desktop, you may not want to use the hibernate feature which creates another file which is equal to the amount of RAM that you have on the system. You can disable hibernation from an elevated command prompt with powercfg -H off

Finally, check your system restore settings and lower the amount of disk space that system restore is consuming on your C drive. Right click Computer, Properties, System Protection, highlight C, click on Configure and you can see how much space is being used and how much space it could use at a maximum.


Generally speaking, with 12GB of RAM...a pagefile isn't likely to be necessary. It's possible though to stumble upon an application from time to time which is required to see a pagefile on the system. If this is the case, you might get an error saying that you don't have any virtual memory configured. But like I said above, if you have another hard drive which can be used for storing of the pagefile...you might want to just move it and leave it in place just to be safe.

Somehow, it didn't click when you said 12GB. The system partitition that I was talking about is usually only 100-200MBs. As I said before, look in Disk Management to see what it shows for partitions, also check the freespace to see if the visible partition space and freespace add up to the size of your SSD. If so, there wouldn't be any place left for another partition.

@pparks1

I was thinking to go to the System Restore earlier and see what's going on there but now I remembered I set this to 1% of C: right after installation. On the other hand, Hibernation turn-off released 9 GB right away and the pagefile was set to "system-managed" and yet it was ~12 GB. I set this to 800-1024.. This will take effect afte restart of course, but still there are like 10 GB missing. I'll do a thorough search of large system files after the restart.

@seekermeister

I'm quite certain it said GBs because I remember being shocked
I have nothing big installed on the SSD rather than a few small 1-10 MB programs I use frequently and about a total of 1 or so GB of Windows Update files... I have no large temp files, nor files in Documents/Downloads but still let's say all that is another gig.
I have ~19GB of free space now, 10 more after restart, windows/program files is 16 or 20 GB = 49... 10 gigs still gone, although I'm sure it's more than 10.

Anyway, let me now restart.
Thank you guys.

I run an 80GB SSD. I turned off hibernation, put my pagefile on another drive. I also redirected by browser caches to the standard drive.

With Windows 7 64-bit installed, plus the apps that I use and Wolfenstein and Crysis being used, I'm consuming about 25-30GB of space total. I have around 45-50GB free on my drive, which Windows reports as 74GB. And I have the 100MB system reserved partition as well.

Generally speaking, Windows will set the page file to be equal to the amount of RAM in your box. Thus, 12GB would be about right if it's system managed.

Run a tool like WinDirStat or TreeSize free...which will show you which folder are consuming the space. And don't be concerned about C:\windows\winsxs...it's not really as big as these tools report it to be. I have demonstrated this point in this thread;
WinSXS Folder not actually consuming lots of space
