Software

Office subscriptions, perpetual licences and OEM keys:

nearly every licence that changes hands is one of the three. A subscription such as Microsoft 365, Adobe Creative Cloud or a yearly ESET or Norton card runs for a fixed term and then has to be renewed. A perpetual licence such as Office Home or a retail copy of Windows 11 is paid for once and kept. An OEM licence is the one preinstalled on a laptop or desktop: it belongs to that machine and leaves with it when the machine is sold. Microsoft 365 runs on several devices, adds cloud storage and keeps the apps current; Office Home installs on one computer and never charges again, but it never gains new features either. If you study at Universidad de Panamá or work for a company on Microsoft 365, look at what your institutional account already includes before paying for a year.

Windows 11 Home Single Language on a laptop:

plenty of laptops sold in Panama ship with this edition, which runs in one display language, Spanish or English, and will not add another through the normal settings. If someone in the house needs Windows itself in the other language, the straightforward fix is an upgrade to Windows 11 Pro. The edition shows under Settings, System, About, and it is worth a look before buying a used machine or a licence for it. A home-built tower from desktops that never had a licence needs a full retail copy instead.

Paying once for Office against paying every year:

a year of Microsoft 365 for one person runs around $75 to $85 in Panama and a one-off Office Home licence around $130 to $145, so paying once comes out ahead inside two years if you never need the cloud storage or a second device. Keys offered for the price of a lunch are mostly volume licences meant for companies, resold OEM keys or activator tools that switch Windows on until the next check switches it off. Pre-owned software has almost no discount to offer: a card nobody has scratched is worth close to what it costs new, and a redeemed one is worth nothing to anyone but the account that claimed it.

Redeemed keys, family plan slots and Professional Plus boxes:

whether the code has been used is the whole value of a second-hand licence. Once an Office or Microsoft 365 key is claimed it is tied to the Microsoft account that claimed it, so Office bought for an old laptop cannot be handed on after its code went in. A retail Windows key can move to another computer once it is removed from the old one; an OEM key stays with its original machine, so ask for the box or receipt that shows it was bought as retail. Some offers are a place in someone else’s Microsoft 365 Family plan, which lasts only as long as the organiser keeps paying and keeps you in. Treat any boxed Office Professional Plus with suspicion: that edition goes to organisations through volume licensing rather than onto shelves, and counterfeit boxes with a USB stick inside have circulated, some loaded with malware.

Passing on an unscratched activation card:

photograph it front and back with the strip intact, or the box if there is one, and never show the code. Name the product and edition, Windows or Mac, how many devices it covers and, for a subscription, how long it runs. For retail Windows, say so and confirm it is already removed from your own computer. Spare cards often come from someone who bought Office and then got it through work or school, and a buyer who comes in from Penonomé to collect one will want to scratch the strip and redeem the code to their own account on their phone before handing over the money.
