Before you upgrade: checklist (do this first)

  1. Backup important data (file backup + create a system image if you want identical restore).
  2. Confirm system requirements for the target Windows version (CPU, TPM, Secure Boot, RAM, storage).
  3. Check activation state on current PC: Settings → System → Activation (shows “Windows is activated” and key type).
  4. Link your Microsoft account if you use a digital license: Settings → Accounts → Your info and sign in with Microsoft account.
  5. Note existing product key (if retail/OEM): run wmic path SoftwareLicensingService get OA3xOriginalProductKey (may return OEM key) or use a reputable key-retriever tool for installed product keys.
  6. Gather install media and drivers: Download Windows installer (Media Creation Tool or ISO) and latest drivers for your hardware.

Step 1: Avoid eBay and AliExpress

While tempting due to low prices (often $5–$10), these keys are typically volume-license keys sold illegally or keys generated by old algorithms that no longer work. You will likely receive a text file with a key that fails validation.

Option 2: Buy a Legitimate OEM Key ($15–$50)

If you cannot upgrade for free, purchase an OEM license from an authorized reseller like Amazon, Newegg, or Best Buy. Avoid eBay "lifetime keys" for $5—they are often MSDN or Volume License keys that will be revoked.

3. Botnet Recruitment

Your PC could become part of a botnet used for DDoS attacks or spam distribution without your knowledge. The only sign? Slower internet and high CPU usage.
