Reinstall and Reactivate Office 2019 via Microsoft Account
Use your connected Microsoft account to manage your subscriptions and reinstall Office on the new PC.
Office 2019 licenses (retail) can be transferred to a new computer, but the license can only be active on one machine at a time. While there is no formal 'deactivate' button, uninstalling it from the old PC is highly recommended to prevent activation conflicts.
Open the Control Panel on your old computer, navigate to 'Programs and Features', select Microsoft Office 2019, and click 'Uninstall' to free up the license.
On your new PC, open a web browser and navigate to the Microsoft Account 'Services & subscriptions' page. Log in with the account used to purchase Office.
Locate your Office 2019 purchase in the list and click 'Install'. Follow the on-screen prompts to download and run the setup file.
Once installed, open any Office application like Word. You will be prompted to sign in to activate the product using your Microsoft account.
Transfer Your Windows 10 Professional License
Reactivate Windows on the new PC using a digital license or a retail product key.
Contact Support for Activation Failures
If you encounter activation limit errors during the transfer, Microsoft Support can manually verify and transfer your rights.

Frequently Asked Questions
Do I need to deactivate Office 2019 on my old computer first?
Office 2019 does not have a dedicated 'deactivate' button. Instead, you should uninstall it from the old computer before installing it on the new one. If prompted with an activation limit error on the new PC, you may need to use the telephone activation method to complete the transfer.
Can I transfer an OEM Windows 10 license to a new PC?
No, OEM (Original Equipment Manufacturer) licenses are tied to the motherboard of the original computer they were installed on and cannot be transferred. Only Retail licenses purchased separately can be legally transferred to a new PC.
Where can I find my Office 2019 product key?
If you purchased Office 2019 digitally, the license is typically linked to your Microsoft account and can be managed under the 'Services & subscriptions' page. If you bought a physical physical copy, the 25-character key is usually located inside the product box.
