Free Space Shrinking

[Kostas Chris]

Hi guys i need you help!The free space of my hard drive is shrinking like crazy from 420 gb it went to 120 in almost one week!I didnt install anything but i have been having bsods 0x93 which are now gone.Also i have windows uptade problems.As you can see in the attached screenshot the windirstat says that i use 550 gb but windows says i use 806 gb!

Hmm, maybe WinDirStat is not showing System Volume Information folder.

One possibility - What's your anti-virus? Avast?

Unhide Protected System files from folder options and see if WinDirStat will show a better result.

Do you really have a 320GB Program Files?

In the WinDirStat menu click Options, and make sure Show Unknown is checked.
If you have space used for <Unknown>, try Wiztree and see if it can list these files.
They have a portable version, no install needed.
Antibody Software - WizTree finds the files and folders using the most disk space on your hard drive

I found this files what are these can i delete them safely?

 

[GokAy]

No, don't mess with them.

You didn't answer question about antivirus? Avast or no?

Also check this:
Start Menu - Computer (right click) - Properties
System Protection - Configure

What is the Max Usage %?

 

[DavidE]

Do you use Avast ?
Avast can cause problems and set System Restore to 50% disk usage.
Check how much space you use for System Restore.

edit: GokAy beat me to it

 

[Kostas Chris]

I have uninstalled avast the previous week because a member of the forum stated that it may occur bsod's so now i use mse. yes it is 50 %

 

[GokAy]

Ok, default is 10%. Adjust it to whatever you want.

Restart PC.
Check System Restore again and create a manual system restore.
run cmd: vssadmin list shadowstorage

 

[Kostas Chris]

It wont let me set it at 10 only at 15 is it normal?

 

[DavidE]

Maybe you need to delete restore points first and then try and set it to 10%.
Give that a try.

[Kostas Chris]

Wait a moment i have a option selected which is turn off system protection? I am confused

 

[DavidE]

Reboot the PC and then see if you can set things the way you want.

 

[Kostas Chris]

When i try to click ok i get an error code 0x80071A91. The text is in greek and im not sure if i can translate it properly

 

[DavidE]

You probably need to get the BSOD problem fixed first, then fix the Windows Update problem, then come back to this.

When you uninstalled Avast, did you use the Avast uninstall utility ?

 

[Kostas Chris]

Yes i did.But i havent had a bsod for a while now

 

[DavidE]

Then let Noel know in your Windows Update thread.
Googling 0x80071A91 seems it might be related to Windows Update problems, or SFC errors, or ...
See if Noel can find anything in the Windows Update issue that might help fix this issue.
