Windows Bootcamp Size Issue

[crovali]

I installed Windows 7 on my new 2012 iMac not too long ago with a bootcamp partition size of 160GB. After I installed it, it showed that I had already used over 41GB of the bootcamp partition. How is this possible? I only installed Windows 7 and all the Drivers. How does that add up to 41GB??

Did you disable hibernate? If not, google how and check your disk space before & after.

Here are some steps you can do to Gain/Reclaim some free space. I know this seems like a lot but it is very detailed. As you go further down in the list your likely going to be saving less and less space (so start from the top).

Also note that OS X and Windows report space differently. (In OS X 1GB is 953.67432MB | In Windows 1GB is 1,024MB)

How to Shrink your Pagefile (To a Minimum of 16MB and a Maximum of 4GB):

1. Open up a Administrator Command Prompt
2. TYPE - wmic computersystem where name="%computername%" set AutomaticManagedPagefile=False
3. Press Enter
4. TYPE - wmic pagefileset where name="C:\\pagefile.sys" set InitialSize=16,MaximumSize=4096
5. Press Enter
6. Restart your Computer

Note that You can also do this through the GUI, but its easier for me to just tell you 2 commands.
Video of How to COMPLETLY disable the Pagefile using the GUI - http://www.youtube.com/watch?v=XM1UZc9AkE4
If you have 8GB+ of RAM I don't see any reason you couldn't completely disable it.


To Set the Pagefile back to default:

1. Open up a Administrator Command Prompt
2. TYPE - wmic computersystem where name="%computername%" set AutomaticManagedPagefile=True
3. Press Enter
4. Restart your Computer

How to disable Hibernation (Sleep will Still work):

1. Open up a Administrator Command Prompt
2. TYPE - powercfg hibernate off
3. Press Enter
4. TYPE - del /A "C:\hiberfil.sys"
5. Press Enter

To Re-Enable Hibernation:

1. Open up a Administrator Command Prompt
2. TYPE - powercfg hibernate on
3. Press Enter

Disabling Hibernation will give you back xGB in HD storage space.
Where xGB is == 75% of your Physical RAM
Example: If you had 4GB of RAM, you would re-gain 3GB of storage space on your Windows Partition.

How to disable System Restore in Windows 7 <-- This is a Youtube link, Click it.

It will probably do it automatically, but you might also want to click the "Delete" button to remove any old restore points.


To Re-enable System Restore: Follow the steps in the video but instead of clicking 'Turn off system protection' click "Restore system settings and previous versions of files'.


By default I think its 8ish GB or so on a 50GB Partition. If your careful you should never need it System Restore.

(How) To clean up all files on the computer:

1. Open Disk Cleanup by clicking the Start button
   
   . In the search box, type Disk Cleanup, and then, in the list of results, click Disk Cleanup.
   
   .​
2. In the Drives list, click the hard disk drive that you want to clean up, and then click OK.
   
   .​
3. In the Disk Cleanup dialog box, click Clean up system files.
   
   If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
   
   .​
4. In the Disk Cleanup: Drive Selection dialog box, select the hard disk drive that you want to clean up, and then click OK.
   
   .​
5. In the Disk Cleanup dialog box, on the Disk Cleanup tab, select the check boxes for the file types that you want to delete, and then click OK.

6. In the message that appears, click Delete files.
   
   .​
   The More Options tab is available when you choose to clean files from all users on the computer. This tab includes two additional ways to free even more disk space:
   
   .​
   • Programs and Features. This option opens Programs and Features in Control Panel, where you can uninstall programs that you no longer use. The Size column in Programs and Features shows how much disk space each program uses.
     
     .​
   • System Restore and Shadow Copies. With this option, you can delete all but the most recent restore point on the disk.
     
     .​
     System Restore uses restore points to return your system files to an earlier point in time. If your computer is running normally, you can save disk space by deleting the earlier restore points.
     
     .​
     In some editions of Windows 7, restore points can include previous versions of files, known as shadow copies, and backup images created with Windows Complete PC Backup. These files and images will also be deleted. For more information about System Restore, see What is System Restore?
