I notice that when doing a Recovery/Reset this PC/Remove everything operation, Win10 will create a windows.old folder similar to the one it created when doing a win7/8 to win10 upgrade. But the folder created during the upgrade always disappeared after 30 days. Does anyone know if that happens with the windows.old folder created when doing a Recovery/Reset this PC/Remove everything operation? Does it disappear on its own also? Or is a manual removal required?

I never wait till it auto deletes... After let's say a week, if I like the running version of Win, I delete it manually.

Thanks, but that's not what I'm asking. I do that as well. I want to know if the windows.old folder will auto delete like it does after the upgrade.

No, not that I'm aware of btw I've used the refresh/reset option a fair few times. You'll probably get a definitive answer on MS' forums.

Thanks. Btw, what's the difference between the Recovery/Reset this PC/Remove everything option and the Fresh Start option?

No it doesnt auto delete, only the oldest system restore updates do after system restore storage pencentile is saturated. Its there so you can revert back to the previous version of windows, or if you parallel install the same version of windows.

It does auto delete - eventually. Next time Windows updates and creates a new Windows.old file, that old Windows.old file will be overwritten. Then in 30 days, it will auto delete.

If you have lots of free disk space, I say just leave it. It is not hurting anything. But if running low on disk space, or you just want to get rid of it, you can delete it manually, use Windows own Disk Cleanup to clean out "Previous Windows installation(s)" files or use CCleaner. But for sure, I would wait at least a week or two to make sure you will not need to roll back to that previous version.

Not from my experience. I had Windows.old and Windows.old (1) last time something was updated...

After updates, I just run Disk Cleanup and clean the mess. When it fails to do so, follow this guide:

Maybe things were shuffled around, but the basics haven't changed...

:eek: Well, you got me to question myself. So I just checked the 6 W10 systems I have here. I opened a command prompt, changed to the root directory and ran the following command: dir windows.ol* /s to look for all windows.old files in all folders and subfolder.

Only one windows.old file was found on each system so not sure what to say there. I will keep an eye out for others from now on.

It's not that. I've done this several times on my builds before. What I was wondering is if they would eventually dissapear on their own. Or better yet, if there was a way to do a restore and not have W10 create a windows.old folder. I want to prepare the system for resale and not have the windows.old folder left for someone to use.

Yes, they will disappear on there own. Use to be 30 days or when you do a disk clean up, there is a option to remove it properly under clean up, system files

Delete it then, if you intend on not going back to a previous version.

...use Windows own Disk Cleanup to clean out "Previous Windows installation(s)" files...
This. Windows won't let you delete it manually and there's no reason to rely on third party software to remove it. Bare in mind that cleanup has to be ran as admin to remove that folder.

It's not that. I've done this several times on my builds before. What I was wondering is if they would eventually dissapear on their own. Or better yet, if there was a way to do a restore and not have W10 create a windows.old folder. I want to prepare the system for resale and not have the windows.old folder left for someone to use.
Just erase and clean install Windows from the Media Creation Tool. Erasing will destroy the data on the drive so there's no chance of recovery and there will be no Windows.old folder because you're installing the most recent version of the operating system.
