Windows 10: Win7 to win10 can i delete this folder?

I went from Windows 7 pro to Win10 pro and i noticed that there is a Windows.old folder on the C drive that is 22gig in size, if im correct that is the windows 7 installation right? can this folder be deleted?

Deleting Win7

I loaded Win 10 over Win7 on my PC. When I start my computer the screen shows all the icons etc as it was on Win7. To start win10 I need to click on the windows icon in bottom left of screen. Can I delete Win7 so the Pc starts up in Win10 mode?

 

Removing residual Win-7 after the free uopgrade to Win10

When I upgraded to the free Win10 last year, it stated that I could revert to Win7 at any time as long as the Win7 files were retained. OK, I think at this point I will not be restoring Win7. So how to I delete all the Win7 files that was retained? Is
there a uninstall or is it a folder or hidden folder that can be simply deleted.

So far, I have not seen this issue addressed as is the reverse.

 

Windows.old contains your old Windows 7 to allow you to roll back if you choose. Once deleted you cannot roll back.
Here's how to delete it:
Open Admin command pront, copy and paste the following line then run:
%SystemRoot%\System32\Cmd.exe /c Cleanmgr /sageset:65535 & Cleanmgr /sagerun:65535

NOTE: Put a check mark on everything except: Setup logs files, answer Yes when prompt for confirmation

 

thanks topgundcp, i want to delete it because Windows is installed on a 120gig ssd drive with limited space. i dont plan on going back to win 7 and if i do just do a clean rebuild.

 

i ran the command and selected everything except system logs and clicked on clean up system files it does no prompt me with anything. i then click ok and the window closes the windows.old folder was not deleted?

 

ok i finally ran the cleanup but the windows.old folder is still there. I need to free up room for my hard drive it is only 120gig ssd.

 

Boot into safe mode by holding down shift while clicking restart from the power icon. Try deleting it in safe mode.

 

thanks finally worked after i changed the owner of the folder, its weird Win10 is pretty anoying with folders and files even though im a admin i have to make myslef owner of files and folders.
