Tutorial – How to Delete windows.old in Windows 10

Removing the windows.old folder is a smart move if you’re looking to free up significant disk space on your computer. This section will walk you through the simple, step-by-step process using Windows’ own tools, ensuring you can confidently reclaim that storage without any fuss. Ready to clean house? Let’s dive in.

Step 1: Open File Explorer.

This is your gateway to everything on your computer, a bit like your digital filing cabinet.

You can usually find File Explorer by clicking the folder icon on your taskbar at the bottom of your screen. If it’s not there, just press the Windows key + E on your keyboard, and it’ll pop right up. It’s the starting point for almost anything you want to do with your files and drives.

Step 2: Right-click your C: drive and select “Properties.”

The C: drive is usually where your Windows operating system and all your main programs live.

Once File Explorer is open, look on the left-hand side for “This PC” or “My Computer.” Click on that, and you’ll see your drives listed. The C: drive typically has a Windows logo next to it. Right-clicking it brings up a menu, and “Properties” is what we need to get to the disk tools.

Step 3: Click the “Disk Cleanup” button.

This button is found within the Properties window, under the “General” tab.

After clicking “Properties,” a new window appears with different tabs. Make sure you’re on the “General” tab, and you’ll spot the “Disk Cleanup” button near the bottom. Click it, and Windows will start scanning your drive for temporary files it can remove.

Step 4: Click “Clean up system files.”

This is a really important step because the initial Disk Cleanup scan won’t show the windows.old folder.

After the first scan, a new Disk Cleanup window will appear, listing various files you can delete. However, the windows.old folder isn’t usually among them yet. You need to click “Clean up system files” to run a more thorough scan that requires administrator permissions, which then reveals deeper system-related temporary files, including your old Windows installation.

Step 5: Scroll down and check the box next to “Previous Windows installation(s).”

This is the entry you’re looking for; it represents the windows.old folder.

Once the system file scan is complete, a fresh list will appear. Take a moment to scroll through it until you find “Previous Windows installation(s).” You’ll notice it probably takes up several gigabytes of space. Click the checkbox next to it to select it for deletion.

Step 6: Click “OK” and confirm the deletion.

Windows will ask you to confirm that you really want to delete these files.

After you’ve checked the box, hit “OK.” A confirmation message will pop up, asking if you’re sure you want to permanently delete these files. As long as you’re certain you don’t need to go back to your previous Windows version, go ahead and click “Delete Files” to finalize the process.

Once you complete these steps, the windows.old folder will be permanently removed from your system. The disk space it was occupying will be freed up, making your computer feel a little lighter and giving you more room for new files and applications. Just remember, after this, you won’t be able to use Windows’ built-in option to revert to your previous operating system.

Tips for Deleting windows.old in Windows 10

• Always wait at least 10 days after a Windows upgrade before deleting the windows.old folder. This gives you a safe window to revert if something isn’t working right.
• Before hitting delete, make sure you don’t actually need to roll back to your previous Windows version. Once windows.old is gone, there’s no easy going back.
• Consider backing up any critical personal files to an external drive or cloud service before performing any major system cleanup, just for extra peace of mind.
• While in Disk Cleanup, check other categories like “Temporary files,” “Downloads,” or “Recycle Bin” to see if you can free up even more space.
• Never try to delete the windows.old folder manually by dragging it to the Recycle Bin; Windows protects it, and attempting to force delete can cause system instability.
• Ensure you are logged into an administrator account when performing these steps, as system file cleanup requires elevated permissions.
