How to Delete Windows.old in Windows 11? [Easy Steps]
When you upgrade your system to Windows 11, the operating system automatically creates a folder named Windows.old. It is stored in the C drive and contains previous system files, program files, and user data. This folder is essential if you want to revert to your old version of Windows within the allowed rollback period, typically 10 days.
After this rollback period expires, the system may automatically delete the folder. However, in many cases, it remains on your system and continues to occupy disk space unnecessarily.
In this guide, you will learn how to safely delete Windows.old in Windows 11, but before proceeding, ensure that you do not need any files from your previous installation, as deleting this folder is permanent and cannot be undone.
Now, let’s proceed!
How to Delete Windows.old in Windows 11?
To delete Windows.old folder in Windows 11, open Settings, go to System, select Storage, click on Temporary files, check Previous Windows installation(s), and then click Remove files. Alternatively, you can use the Disk Cleanup tool and select Clean up system files to remove Windows.old folder safely.
Step 1: Going to Storage Settings in Windows 11
The first step involves accessing the storage management section of Windows 11, where temporary and unnecessary files can be reviewed and removed.
Press the Windows key + I on your keyboard to open the Settings app. Once the Settings window appears, click on System from the left-hand menu. After that, select Storage from the list of options.
In the Storage section, Windows will analyze your disk usage and display categories such as apps, system files, and temporary files. This section helps you identify what is consuming space on your computer.
Wait for a few seconds until the storage scan is complete. Once done, you will be able to proceed to the next step.
Step 2: Access Temporary Files
After opening the Storage settings, the next step is to locate the Temporary files section, which includes the Windows.old folder.
Scroll down slightly and click on Temporary files. Windows will again take a moment to scan and list all removable files, including cached files, recycle bin contents, and previous Windows installations.
Look carefully through the list until you find an option labeled Previous Windows installation(s). This option represents Windows.old folder.
You may also see other categories such as Windows Update Cleanup, Delivery Optimization Files, and Temporary Internet Files. While you can select these as well, focus specifically on the previous installation files if your goal is to delete Windows.old.
Step 3: Select Previous Windows Installation Files
Once the list of temporary files is displayed, you need to select the correct option to remove the Windows.old folder.
Find the checkbox labeled Previous Windows installation(s) and click on it. This selection tells Windows that you want to delete the backup files from the earlier version of your operating system.
Make sure you double-check your selection before proceeding. If you accidentally remove other files, it may affect saved data or cached settings.
After confirming your selection, move on to the next step to remove the files permanently.
Step 4: Remove Windows.old Folder
After selecting the appropriate files, you can now delete the Windows.old folder.
Click on the Remove files button located at the top of the Temporary files section. Windows will prompt you to confirm the deletion.
Once confirmed, the system will begin the cleanup process. This may take several minutes, depending on the size of the Windows.old folder.
During this process, avoid shutting down your computer or interrupting the operation. Once completed, the system will automatically free up the space previously occupied by the folder.
Step 5: Use the Disk Cleanup Tool as an Alternative Method
If you prefer another method or if the Storage Settings option does not work, you can use the Disk Cleanup tool, which is a classic utility in Windows.
Press the Windows key and search for Disk Cleanup, then open the tool. Select the C drive when prompted and click OK.
Once the tool calculates the space, click on Clean up system files. This will refresh the list and include system-level files such as Windows.old.
Look for the option labeled Previous Windows installation(s) and check it. Then click OK and confirm the deletion.
This method is equally effective and is often used when the Settings app does not display the required options.
Step 6: Verify Deletion of Windows.old Folder
After completing the deletion process, it is important to confirm that the folder has been removed.
Open File Explorer and navigate to the C drive. Look for the Windows.old folder. If the process was successful, the folder should no longer be visible.
You can also check your storage space again by returning to Settings > System > Storage. You should notice an increase in available disk space.
If the folder still exists, restart your computer and check again. In rare cases, you may need to repeat the cleanup process.
