How to install & activate Combo: Windows 10 Pro + Office 2021 Pro Plus

Part 1 — Windows Pro

Activate Windows 10 Pro with your 25-character product key (about 2 minutes):

1. Install Windows 10 Pro using the official Microsoft download on the Download tab (skip if it is already installed). During setup you can click “I don’t have a product key” and enter it later.
2. Connect to the internet and open Settings → Update & Security → Activation (press Windows + I).
3. Click Change product key.
4. Copy your key from My Licence Keys in your account, paste it and click Next → Activate.
5. You will see “Windows is activated with a digital license”. Done!
6. Alternative (Command Prompt as Administrator): slmgr /ipk YOUR-PRODUCT-KEY then slmgr /ato. Check status with slmgr /xpr.

💡 Error 0xC004F050? The installed edition must match the key — a Pro key needs Windows 10 Pro. See our activation error guide.

💡 Microsoft ended Windows 10 support on 14 October 2025. On a supported PC you can install Windows 11 Pro instead and activate it with this same key.

Part 2 — Office 2021 Professional Plus

Install and activate Office 2021 Professional Plus using Microsoft’s official Office Deployment Tool (about 10 minutes):

1. Uninstall any other Office / Microsoft 365 version first: Control Panel → Programs → Uninstall a program. Mixed versions are the #1 cause of activation errors.
2. Download the Office Deployment Tool from the Download tab, run it and extract it to a folder, e.g. C:\ODT.
3. In that folder create a file configuration.xml with this content (put your key in place of YOUR-PRODUCT-KEY):
   <Configuration><Add OfficeClientEdition="64" Channel="PerpetualVL2021"><Product ID="ProPlus2021Volume" PIDKEY="YOUR-PRODUCT-KEY"><Language ID="en-us" /></Product></Add><Display Level="Full" AcceptEULA="TRUE" /></Configuration>
4. Open Command Prompt as Administrator, run cd C:\ODT and then setup.exe /configure configuration.xml. Office downloads and installs.
5. Open Word → File → Account. If it does not say Product Activated, click Change Product Key, paste your key and click Activate.
6. Alternative (Administrator Command Prompt): cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /inpkey:YOUR-PRODUCT-KEY then cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /act.

💡 If setup says the key is not valid for this product, change the Product ID in the XML from ProPlus2021Volume to ProPlus2021Retail and run setup again.
