Disk Space Saver Utility

Last updated on September 26th, 2021 at 02:06 am


Following on from our guide about clearing up disk space on your hard drive, we have now created a very simple batch file called Disk Space Saver Utility that will take care of all the space saving for you by just double clicking a single file!

The batch will delete all of your Windows Updates download and log files and then run through the WinSXS folder and remove anything it can safely remove. Once complete, reboot your machine and you should notice significant disk space has been freed up for you which is particularly helpful if you are using a smaller sized SSD like this Kingston 120GB SSD on Amazon.

First of all you will obviously need to download the file which you can do so by clicking the button link above. Once you have the file downloaded, you will then need to ensure that you have full admin rights on your machine – if you do not have full admin on your machine, this process will not work.

Go to the downloaded zip file and unzip it using either the built in Windows function or a free zip program like 7-Zip.

You will find in the zip file a batch file called dssu.bat (for Disk Space Saver Utility). You should then go ahead and run the batch file as an administrator – not just local administrator but it must be elevated with administrator permissions. If you are unsure on how to do this, please take a quick look at the guide video below:

As soon as you have run the program it will start the process, first it will stop your Windows Update Service, then clean out your Windows Update cache:

Once it has completed that, it will restart the Windows Update Service.

The batch file will then start to run through the WinSXS folder, cleaning up whatever it can without causing any damage to the Operating System:

You will then be notified once it has fully completed the process. Then, just reboot your computer and check out your disk space saved!

This utility is designed to run on Windows 10 and Windows 8.1 however, you can run it on Windows 7 but the WinSXS part of the clean up will not work and you will see some errors. You will see this in our Windows 7 video demo below. This does not do any damage to your machine and it will still work in clearing up your Windows Updates cache. As you can see in the video below, on a Windows 7 machine this process saved around 3.5GB in disk space.
