Office activation is the step that links your copy of Word, Excel and PowerPoint to a valid license. An Office key is never entered in the Windows settings: it goes either into an Office app or into your Microsoft account, depending on the edition you bought. Here is how to tell which case applies to you.<\/p>\n
Office 2019, 2021 and 2024 Professional Plus keys are entered on the computer itself. Install the suite with the download link provided with your order, then open Word or Excel: an activation window asks for your key. If it does not appear, go to File > Account > Change Product Key<\/strong>, type the 25 characters and choose online activation. After about thirty seconds, the Account page should read “Product Activated”.<\/p>\n Editions sold in shops as a box or a card, such as Office Home 2024, are redeemed at setup.office.com<\/strong>: sign in with your Microsoft account, enter the key, and the license is attached to that account, which then offers the download. Microsoft 365 and Office 365 plans follow the same logic: they activate when you sign in to the Office apps with the account the plan belongs to.<\/p>\n Before you start, check which version is installed: in Word, File > Account > About Word<\/strong> shows the exact version and whether it is 32-bit or 64-bit. Whatever the edition, keep your key with your invoice: it is your proof of license, and you will need it again after a reinstall.<\/p>\n Whether you need a Microsoft account depends on the edition. Store-bought editions and subscriptions cannot activate without one, while Professional Plus editions activate on the PC with the key alone. When an account is involved, a few rules avoid most surprises:<\/p>\n Not sure which model suits you?
