Windows 10: Around 12-15 gb decrease in C drive after unsuccessful system restore

Yesterday I was facing some problem with my computer with windows 10 home and so I decided to perform a system restore which i had created a few days back ago. After starting system restore and allowing it for almost an hour, the laptop screen was still showing initializing system restore. So i forcefully shutdown my laptop and started it again. After starting i got a message that system restore not successful. After that when i went and check the free disk space of system volume C it got decrease by around 12-15 gb.*I went and deleted all previous restore point, clean up disk space and also using 3rd party software tried cleaning disk space but still have not recovered this 12-15 gb space.*

After that i went to setting and check the storage as to where this space has been occupied. It is showing that in others around 18 gb has been allocated, for which the windows is showing " There are some of the largest folders we couldn't characterize" (Screenshot attached).

Please help me recover this space.
Thank you

Around 12-15 gb of Disk size decrease in System Volume , Drive C after unsuccesful system restore

Thank you for the information.

System Volume Information is a hidden folder rooted in your C drive. This is where Windows stores System Restore points. We do not recommend deleting this folder or tampering any files inside it since your recovery partition might get corrupted as well,
preventing you from doing a reset (to factory settings) or system restore in the future.

Around 12-15 gb of Disk size decrease in System Volume , Drive C after unsuccesful system restore

I am Sorry but this is not the reply i am looking from WINDOWS. I understand very well that reinstalling window would solve this problem but that should be last resort and that too for a seroius problem. I am expecting an answer which would solve my problem
without reinstalling windows.

Thank you

 

I tried treesize and it is showing
windows folder has 20.9 GB allocated out of which 6.9 GB is for winsxs
System volume information has 12 Gb allocated out of which 11.5 GB allocated for System Restore. Can i delete this folder? How?
See attached screen shot

 

Go to control panel, system, system protection, configure, and delete all existing restore points. Then create one of course. You can limit size of restore point storage as well.

 

Deleting system restore from control panel, manage system restore point is not helping as it is showing only 500 mb size.

 

Have you run disk cleanup, and selected to remove system installation files?

 

This option is not coming during disk clean up or clean up system files

 

Ccleaner will probably sort it out.

 

From admin command prompt you could run cleammgr.exe in extended mode. Type this in your command window.

%SystemRoot%\System32\Cmd.exe /c Cleanmgr /sageset:65535 & Cleanmgr /sagerun:65535

 

Try disabling system protection completely and reboot then check it again with TreeSize.





That should delete all restore points and you have 12GB there - mostly from Store apps it seems.

If you want you can enable system protection again after (and set some limit with the slider in the picture above) and then create a new one.

 

Tried Both of the options. Its not working *Sad

 

This is not working as it is showing only 500 mb occupied. i tried deleting but its not freeing that 12 GB space

 

Can i manually delete it using treesize?

 

Try it.
