Downgrading from Windows 11 to Windows 10 is possible, but the method depends on how long ago you upgraded and whether you have a backup. Here’s a step-by-step guide:
đź§ Option 1: Roll Back Within 10 Days of Upgrade
If you upgraded to Windows 11 less than 10 days ago, you can revert easily.
Steps:
- Open Settings → Go to System → Recovery
- Under Recovery options, click Go back
- Follow the prompts to restore Windows 10
⚠️ After 10 days, Windows deletes the old files, and this option disappears.
🗂️ Option 2: Clean Install of Windows 10
If more than 10 days have passed, you’ll need to reinstall Windows 10 manually.
What You Need:
- A USB drive (at least 8GB)
- Another PC to download the Windows 10 ISO
- Backup of your files (this process erases everything)
Steps:
- Download the Windows 10 Media Creation Tool from Microsoft: https://www.microsoft.com/software-download/windows10
- Run the tool and create a bootable USB drive
- Plug the USB into your Windows 11 PC
- Restart and boot from the USB (you may need to change boot order in BIOS)
- Follow the installation steps and choose Custom Install
- Format the Windows partition and install Windows 10
✅ After installation, install drivers and updates. You’ll need to reinstall apps manually.
🛡️ Tips Before Downgrading
- Backup your data: Use OneDrive, external drives, or cloud storage
- Check license: Windows 10 should activate automatically if your device was previously licensed
- Drivers: Visit your device manufacturer’s website for Windows 10 drivers
To identify whether your Windows 11 license is original before formatting, you can use a few built-in tools to check the license type and activation status. Here’s a practical guide tailored for you:
âś… Step 1: Check Activation Status
This tells you if Windows is activated and how.
- Go to Settings → System → Activation
- Look for:
- “Windows is activated with a digital license” → Genuine
- “Windows is activated with a digital license linked to your Microsoft account” → Even better—safe to format and reactivate
đź§Ş Step 2: Use Command Prompt to Check License Type
This reveals whether your license is OEM, Retail, or Volume.
- Open Command Prompt as Administrator
- Type this command and press Enter:Code
slmgr /dli - Look at the Description:
- OEM → Pre-installed by manufacturer (safe to format, auto-activates)
- Retail → Purchased separately (keep your product key)
- Volume → Enterprise or institutional (may need reactivation)
🔍 Step 3: Reveal the Product Key (Optional)
If you want to back up your key before formatting:
Option A: Command Prompt
cmd
wmic path softwarelicensingservice get OA3xOriginalProductKey
Option B: PowerShell
powershell
powershell "(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey"
📝 Note: These commands work best for OEM keys. Retail keys may not show up this way.
🛡️ Step 4: Link License to Microsoft Account
Before formatting, make sure your license is linked:
- Go to Settings → Accounts → Your Info
- Sign in with your Microsoft account
- Then go to Settings → System → Activation
- Confirm it says: “Windows is activated with a digital license linked to your Microsoft account”
This ensures automatic reactivation after reinstalling Windows 10 or 11.

Amazon sellers list Windows 10 keys; many are legitimate OEM/retail sellers but there are also risky/volume-key listings that may stop activating later. Recommend: pick sellers with strong history and seller guarantees, and prefer official boxed/retail listings. Amazon India
