Huge size of the system32/config folder

Question

My 128 GB SSD disk is running out of space, so I am looking for the multiple ways to save the disk space:

• Disabled the hibernation,
• Cleaned up the Windows backup-data,
• Moved the swapfile to other disk

I've downloaded the TreeSize Free app, and it has detected that the C:/Windows/System32/config folder is eating 68 192,0 MB(!) (contains 191525 files) which is obviously out of the standard behaviour.

Is that a known issue? How can I fix the config folder size?

I am using Windows 8.

Solution

According to some postings over on the Microsoft forums, http://support.microsoft.com/kb/2795944/EN-US should have resolved that bug and cleaned up the excess files... can you verify that you have that update or something that supersedes it?

I personally would not touch this folder if you want a system that actually boots. I would run the Disk Clean-up tool. You can also disable the creation of System Restore points.

You run a defragmentation routine on a SSD!!! Why would you do that? SSD storage is not only suppose to be fragmented it also not relevant.

Worth a read if you have Nvidia hardware installed

@Ramhound Not really on my SSD - Windows is automatically skipping the SSD defragmentation. Yeah, I have Nvidia hardware drivers installed.

Are we talking about Windows 8 or Windows 8.1. Well the support article that was linked below seems to confirm your running Windows 8 and not Windows 8.1 you might consider upgrading to avoid problems like this.

Thanks. I had the Windows Updates disabled for about 8 months... Didnt even noticed. I will install the update and will let you know about any progress!

So I have just installed the KB2795944 update and nothing has changed. Unfortunately.
