You can not just delete a normal app when you uninstall an operating system. You have to follow a certain process if you want to get rid of Windows 10 so that you can install a different OS, go back to an older version, or wipe a PC clean before sale. If you do not do it right, you could lose your data forever or brick your computer. Step-by-step instructions on how to safely remove Windows 10.
Can You Actually Uninstall Windows 10?
Since an operating system can not delete the files it is using to run, you can not technically “uninstall” Windows 10 from within Windows. You should instead format (wipe) the part of the hard drive where Windows 10 is installed. Usually, booting from a USB drive or using the built-in Windows Recovery Environment gets this done outside of the normal desktop environment. Once the drive is formatted, Windows 10 is gone for good. The computer is then ready for a new operating system or to be thrown away safely.
Step 1: Back Up Your Files and Important Data
You need to make sure your personal information is safe before you even think about changing Windows 10. You can delete everything on the drive for good if you format it.
What You Should Save Before Removing Windows 10
Do not just make a copy of the Documents folder. Export your browser bookmarks, keep your software licence keys, and make a copy of any game saves that are in hidden AppData folders. When you remove the OS, you will also lose your access to any cloud services you use, so make sure you have your login information handy.
Where to Store Your Backup
Always keep your backup on a different partition from where you install Windows. Never put your Windows installation on the same drive as your backup. For extra space, use a USB hard drive, a flash drive with a lot of space, or a reliable cloud storage service like Google Drive or OneDrive. PCMag’s data backup guide says the 3-2-1 rule is the safest way to back up your data: keep three copies on two different types of media and one copy somewhere else, like the cloud.
Step 2: Prepare Windows Installation or Recovery Tools
To wipe the drive, you need a tool that runs independently of your current Windows 10 installation.
When You Need Installation Media
Before you can install a different OS (like Linux) or do a clean install of Windows 11, you need to make a bootable USB drive. To make a bootable installer on a USB flash drive that is at least 8GB empty, you can get the official Media Creation Tool from Microsoft’s website. You need to do this before you delete everything on your disk.
Check Recovery Options First
If all you want to do is wipe the computer clean so you can sell it or install Windows 10 again, you do not need a USB drive. You can use the “Reset this PC” feature that comes with Windows to safely erase the drive and have the OS installed again from a hidden recovery partition.
Step 3: Start the Windows 10 Removal Process
Once your data is safe and your tools are ready, you can begin the actual removal process.
Use Reset This PC for a Fresh Start
Going to Settings > Update & Security > Recovery will give you a fresh start if you plan to keep the PC. If you want to reset this PC, click “Get started.” Pick “Remove everything” to get rid of all of your personal files, apps, and settings. If you are selling the PC, choose “Clean the drive.” This takes longer, but it securely erases your data so the new owner can not get it back.
Use Installation Media for Full Removal
Insert your bootable USB drive and restart the computer if you are replacing the OS from scratch. Press the right key (usually F2, F12, Delete, or Esc) while the computer is starting up to get to the BIOS/UEFI boot menu. You can boot from a USB drive by choosing it. This will load the setup screen for your new OS instead of the Windows 10 that was already installed.
Step 4: Remove the Existing Windows 10 Installation
This is the point of no return. Once you complete this step, Windows 10 is gone.
Select the Windows Partition
If you used a USB drive to start up, follow the on-screen instructions until you see “Where do you want to install Windows?” The same thing will happen for Linux. There will be a list of drives and partitions there. Choose the “Primary” partition that is the same size as your C: drive. “Delete” or “Format” will do it. While formatting deletes the data but leaves the partition structure alone, deleting completely gets rid of the partition and leaves only “Unallocated Space” behind.
Continue With Reinstallation or OS Replacement
There is no way to get Windows 10 back after formatting or deleting the partition. Now that you have found an empty spot, click “Next” to install your new operating system. If you want to take the computer apart for parts, just turn it off.
Step 5: Set Up Your PC After Windows 10 Is Removed
If you installed a new operating system, the final step is getting your computer back to full functionality.
Restore Your Files and Apps
Connect your external backup drive and start moving the folders for Documents, Pictures, and Desktop back to where they belong. You should reinstall your important programs, like web browsers, office suites, and security software.
Check for Updates and Drivers
New installations of an operating system do not usually come with all the latest drivers. Run a full update check from the system settings. Sometimes you may need to download specific drivers for your Wi-Fi card, audio chipset, or graphics card from the website of your motherboard or laptop maker to make sure everything works properly.
Consider Moving to a Newer Windows Version
If you removed Windows 10 because it wasn’t working properly, reinstalling it will likely only help for a short time. Microsoft ended mainstream support for Windows 10 on 14 October 2025. Security updates are now only available through the paid ESU (Extended Security Updates) program, which extends coverage for home users until October 2026. Read our guide comparing Windows 11 and Windows 10 to find out whether your hardware can handle the upgrade. Switching to Windows 11 means you’ll keep receiving important security patches and performance updates.
Common Mistakes to Avoid When Uninstalling Windows 10
People most often mess up when they forget to back up hidden files like browser passwords or software licence keys. If you delete the wrong partition in Step 4, you will also make a big mistake. If you delete your “System Reserved” or “Recovery” partitions by accident, you might not be able to start up your PC or use the diagnostic tools that came with the computer. Before you click “Format,” you should always check the drive size and name again.
Frequently Asked Questions
Q: Is deleting the same as uninstalling Windows?
No. You cannot simply drag the Windows folder to the Recycle Bin. Uninstalling Windows requires formatting the entire hard drive partition from outside the operating system using a bootable USB or recovery tool.
Q: Can I still upgrade to Windows 11 for free?
Yes. If you currently have a legitimate, activated copy of Windows 10, the upgrade to Windows 11 is completely free, provided your PC meets the strict hardware requirements (such as TPM 2.0 and a supported processor).
Q: How to completely wipe out Windows 10?
To completely wipe the OS and make your data unrecoverable, use the “Reset this PC” feature in Settings, select “Remove everything,” and then choose the “Clean the drive” option. This securely overwrites the disk.
Q: What will I lose when upgrading to Windows 11?
You will lose a few deprecated features, such as Internet Explorer, the Math Input Panel, and the ability to move the taskbar to the sides or top of the screen. However, all your personal files and compatible apps will remain intact.
Remove Windows 10 Safely With the Right Preparation
Uninstalling Windows 10 is a straightforward process as long as you prepare properly. By backing up your critical data, creating the right bootable media, and carefully formatting the correct partition, you can safely wipe your drive without fear of permanent data loss. Whether you are upgrading to a new OS or wiping an old machine to sell, following these five steps ensures a clean, secure transition.
If your current PC is struggling to run modern operating systems, it might be time for a hardware upgrade rather than just a software reinstall. Explore the powerful, space-saving lineup of GEEKOM Mini PCs to find a modern, Windows 11-ready machine that fits perfectly on your desk.
