If the command line isn't your thing, the Settings app offers exactly the same Home-to-Pro upgrade through a guided, entirely graphical flow — same end result as the SLMGR method, just click-through instead of typed commands.
Before You Start
- A PC currently running Windows 10 Home
- A genuine Windows 10 Pro OEM key
- An internet connection
1.Open Activation settings
Settings > Update & Security > Activation.
2.Start the edition upgrade
Under "Upgrade your edition of Windows," select "Change product key" (the exact wording varies slightly by build) rather than "Go to Store," since you already have a key to enter.
3.Enter your Pro key
Type in the 25-character OEM Pro key exactly as provided in your order email, then click Next.
4.Let Windows finish upgrading
The PC applies the edition change and prompts for a restart. Files, apps, and settings remain untouched throughout.
5.Restart to complete the switch
Restart when prompted — the edition change fully applies only after this reboot.
Confirm you're now on Pro
Settings > System > About should show "Edition: Windows 10 Pro" after the restart, and Activation should show as activated with the new key.
Troubleshooting
| Issue | Likely Cause | Fix |
|---|---|---|
| "Change product key" option is missing | Some builds label this differently or bury it under "Go to Store" first. | Select "Go to Store," then look for a "I want to enter a product key instead" link on the following screen. |
| Key is rejected as invalid | Typo, or the key is genuinely for a different edition or product (e.g. Windows 11 rather than 10). | Re-copy the key exactly from your order confirmation and confirm it's specifically listed as a Windows 10 Pro key. |
