“Do I need to pay again?” is a question with three completely different answers depending on what kind of license you hold. Sorting your software into the right bucket once will save you from both lapsed tools and unnecessary repurchases.

Bucket 1: Perpetual licenses — never pay again (mostly)

Windows retail keys, Office 2021, standalone Excel, Project, Visio, one-time billing software licenses: these do not expire. Three situations feel like they need a repurchase but do not:

  • Reinstalling the OS: your digital license reactivates automatically on the same hardware; Office reinstalls from your Microsoft account or with the original key from your delivery email.
  • New PC with a retail Windows license: retail transfers — deactivate conceptually by retiring the old machine, then use the Activation Troubleshooter on the new one with your linked Microsoft account.
  • “Support ended” notices: end of support means no more security updates, not deactivation. The software keeps working; whether running it unsupported is wise is a separate (real) question.

The one genuine repurchase trigger: an OEM Windows license and a dead motherboard. OEM dies with the board — that is the trade-off you accepted at its lower price.

Bucket 2: Subscriptions — pay on schedule, but audit first

Microsoft 365, most SaaS, some antivirus: stop paying and the service stops. Before any renewal, spend five minutes on three questions:

  1. Did we use it this term? Check the actual usage, not the intention.
  2. Is the renewal price the new-customer price? Auto-renewals often ride above the current promo. Rebuying as “new” through a reseller can legitimately cost less than renewing — same product, different door.
  3. Has a perpetual alternative caught up? If you subscribed to Microsoft 365 but use it like static Office, Office 2021 ends the annuity.
Tip: put every subscription's renewal date in your calendar two weeks early. The choice to renew should be a decision, not a surprise on a card statement.

Bucket 3: Term accounts — plan the cycle

Subscription accounts bought at a discount (streaming, A3-type Office accounts, tool accounts) have a stated validity period. The honest way to run these: treat the stated period as the product, keep your data exportable (files synced locally, lists exported), and simply rebuy when the term ends. The economics usually still beat full-price subscriptions — as long as you never let an expiring account be the only place your data lives.

A 15-minute annual audit

  1. List every piece of paid software you run. Mark each P (perpetual), S (subscription), or T (term account).
  2. For P: confirm you have the key/delivery email archived. That is all.
  3. For S: apply the three renewal questions above.
  4. For T: note expiry dates in your calendar with lead time to rebuy.

Whether you are replacing an OEM license, ending a subscription with a perpetual Office, or rebuying a term account, the store covers all three buckets with instant delivery — and your order history at /account doubles as that license list you just resolved to keep.
