How to delete the Windows.old folder on Windows 10

When you upgrade your computer to a new version of Windows 10, or you install a preview build, the installation process saves a copy of the previous version in the «Windows.old» folder.

This is part of the safety mechanism in case the upgrade process goes wrong. If the installation fails for any reason, the system can use the Windows.old folder to undo the changes. Also, if the upgrade completes successfully, the backup copy of the previous version will be kept to provide the option to rollback in the case the new installation is causing issues.

Although this is a handy feature, if your computer is working correctly after the upgrade, you can safely delete the Windows.old folder to reclaim gigabytes of space.

In this Windows 10 guide, we’ll walk you through the different ways that you can get rid of the Windows.old folder to free up several gigabytes of space to store more important files.

Update November 29, 2018: We’ve updated this article with the latest information for the Windows 10 October 2018 Update.

How to delete the Windows.old folder using Storage sense settings

The easiest method to delete the Windows.old folder from your device is to use the Storage sense with these steps:

1. Open Settings.
2. Click on System.
3. Click on Storage.

Under the «Storage sense» section, click the Change how we free up space automatically option.

Under the «Free up space now» section, check the Delete previous version of Windows option.

Click the Clean now button.

Once you’ve completed the steps, the folder with the previous installation of Windows 10 will no longer be available on your device.

How to delete the Windows.old folder using Temporary files settings

Alternatively, using the Settings app, you can delete the Windows.old folder using the Temporary files settings with these steps:

1. Open Settings.
2. Click on System.
3. Click on Storage.

Under the «Storage sense» section, click the Free up space now option.

Check the Previous Windows installation(s) option.

(Optional) Clear the default selected options if you only want to remove the Windows.old folder to free up space.

Click the Remove files button.

After completing the steps, the folder with the previous installation of Windows 10 will be removed freeing up 14GB to 20GB of storage space on your primary hard drive.

How to delete the Windows.old folder using Disk Cleanup

You can also delete the Windows.old folder using the legacy Disk Cleanup tool with these steps:

1. Open File Explorer.
2. Click on This PC from the left pane.

Under the «Devices and drives» section, right-click the drive with the Windows 10 installation (usually the C drive) and select the Properties option.

In the «General» tab, click the Disk Cleanup button.

Click the Cleanup system files button.

Check the Previous Windows installation(s) option.

(Optional) Clear the default selected options if you only want to remove the Windows.old folder to free up space.

Important: Starting with the October 2018 Update, Windows 10 is deprecating Disk Cleanup in favor of Storage sense, but it adds an option to delete all the contents from the Downloads folder. If you’re using this option, and you have important files in the Downloads folder, make sure to clear this option.

Click the OK button.

Click the Delete Files button to confirm the deletion.

Click the Yes button to confirm the warning.

Once you’ve completed the steps, the Windows.old folder will be removed from your device.

Wrapping things up

While it’s safe to delete the Windows.old folder, if you remove its contents, you will no longer be able to use the recovery options to rollback to the previous version of Windows 10. If you delete the folder, and then you want to rollback, you’ll need to perform a clean installation with the desire version.

It’s also doesn’t mean that Surface Duo is selling a ton either. Instead, the reason for the expansion is a lot more straightforward.

Rmdir : Delete directory from command line

Do you want to delete a directory from Windows command prompt(CMD)? This post explains how to use the command rmdir to delete folders and their contents. You can also find examples for each use case of folder deletion – empty folders, non empty folders, folders with white spaced names etc.

Delete folder from CMD

Run the command rmdir on the folder.

How to delete a non empty folder

The simple rmdir does not work for folders having some content.

Use /s option to delete the folder contents along with the folder. This deletes all subfolders recursively.

Force delete a folder without confirmation

To force delete directory, without being asked for confirmation, we can use /Q switch.

We can also use ‘rd’ in place of ‘rmdir‘. Both names refer to the same command. This command works on Windows 2000, Windows XP, Server 2003, Vista, Windows 7 and 10.

Deleting directory with white spaces in the name

Rmdir can delete files with whitespaces in the name, you just need to wrap up the folder name in double quotes as shown in the below example.

Delete contents of a directory but keep the directory

The usecase here is to delete all the contents of the directory but keep the parent directory so that we do not need to create it again. rmdir /Q /S does not work here as it deletes the parent directory too. Rather the below commands should do the trick.

This works in 2 steps – the first command deletes all files, whereas the second one deletes all subdirectories.

Errors

To delete a directory, you should have appropriate access permissions on the directory. Otherwise rmdir throws ‘Access denied’ error.

Thanks dude..I was looking for command line way of deleting nonempty folders.. cheers.

Good old DOS….something tells me one day the world will be saved by a DOS operation. ; )

cannot delete… access is denied. am trying to delete a directory on a flash drive. cannot access permissions because explorer isn’t working. using win7

Note:
Don’t forget to leave a “space” in the command line..
rmdir /Q /S_“folder with spaces in the name” I meant “space”, ait’t “underscore”. And upper case of “S”. Good luck!

Hi
can you show me an example of command to delete this path in bat file.
C:\Program Files\Microsoft Office Communicator

am not able to do this . some error s

Is this in Windows 7/Vista?.
If so then you need to take ownership of the files. You can do that with below command from elevated administrator command prompt.
takeown /F «c:\Program Files\Microsoft Office Communicator» /R /A

then run the below command to delete this folder.

rmdir /S «c:\Program Files\Microsoft Office Communicator»

cd program files\microsoft office communicator
then enter press
rd /s “filename”
Then enter

I am getting the following error “The process cannot access the file because it is being us
ed by another process.” what should be the case now?

You should not have the Dir you want to delete open… Close it and then try the command again

OMG! Thank you! Was trying to delete the remaining empty folders of an old eset nod, but couldn’t. This did the trick (hoping). I’m just wondering if its still in the background somewhere. T.hanks again

in programatically if any changes in the inner files or directory after delete the parent directory doesnot work
eg:
system(“rmdir /s/q \””d:/test/hari\””);——>it works
but after
system(“rmdir /s/q \””d:/test\””);—–>it doesn’t work

Thank you for these still useful tips.

That worked verywell. Thank You
