Factory reset... now missing 40+ GB of hard drive space?

Have you done a clean install or other is there a windows.old folder?

Just did this, I haven't found a definitive answer yet doing some searching so I figure I would ask here...

Is $SysReset folder safe to delete?

I'm running an ASUS laptop that had Win 10 Home already loaded and if I want to do the reinstall I just hit the reinstall button... will deleting the folder mess up anything there?

There also is a Windows.old folder

You have to run diskclean whe its done on the right is an option to check system files it will then run again and give you the option to remove windows.old you can delete it normally as its a system folder

I like running disk clean by running this in a Command Prompt (Admin). I actually have it saved as a one line batch file on my desktop that I Run As Administrator:
%SystemRoot%\System32\Cmd.exe /c Cleanmgr /sageset:65535 & Cleanmgr /sagerun:65535

Then I just always select everything in the list to delete.

Unfortunately the Cleanmgr didn't free up any space.

I did a fair amount of searching and found nothing telling me I can't delete the folder.

After half an hour of more searching on how to delete the folder, how to change ownership, then being told I can't make changes because I need permission from [name] even though that is both me and the user I am logged on as (with admin privileges) I just ducked out into safe mode and was able to delete most of the folder... bringing my free space up to 80gb.
