How do i reduce the size of the winsxs folder in Windows 7?

I have installed Windows 7 about 3 months ago and now have been told i have no hard drive space. Thinking this is strange since i should have about 20Gb spare i then went through all folders and found that a folder called "Winsxs" under the Windows folder is taking up all of my hard drive space. How can i get rid of this folder? If i can't then how do i reduce the size and stop it from ballooning again?

Looking at other forum sites it looks like i need SP1 for Windows 7, which will then provide a tool to reduce the folder size. However i am unable to download and install SP1 due to not having any hard drive space.

If you're unable to repartition your hard drive as Ron suggested you can do the following to gain free space.


Free Up Space - Increase Hard Drive Space 

The following procedure cleans up files associated with your user account. You can also use Disk Cleanup to clean up all the files on your computer.

1. Click the Start button, in the search box, type Disk Cleanup, then click Disk Cleanup.

2. In the Drives list, click the hard disk drive that you want to clean up, and then click OK.

3. On the Disk Cleanup tab, select the file types you want to delete.

Note: To Remove all System Restore Points Except the Most Recent - Click "Clean up System Files" and you will get another tab called More Options. Now click More Options, then click "Clean up" under "System Restore and Shadow Copies" then confirm the deletion.

4. Click OK on the bottom of the Disk Cleanup window and in the message that appears, click Delete files.



Reduce the amount of space allocated for System Restore. 

1. Start-->Control Panel-->System and Security-->System

2. Next click on the 'System protection' link located in the upper left.

3. In the 'System Properties? window click on the 'System Protection' tab.

4. Locate the 'Protection Settings' box and select/click on the drive letter (usually C:)

5. Now click on the 'Configure' button to change the 'Disk Space Usage' Restore Settings.

6. Move the slider to reduce the amount of disk space System Protection can use (min. 2GB).

7. Click the 'Apply' and then the 'OK' button after you have adjusted the disk space.

Turn of the Hibernation setting

If you don't use hibernation you can turn it off and free up disk space:

2. Right click CMD.exe and click "run as admin"

3. type: powercfg -H off

4. Press Enter

5. Exit and restart your computer










The Winsxs folder is not a normal folder and the size shown is deceptive. It should not be touched.
