Both Retail and OEM keys activate the same genuine version of Windows — the difference is in how the license is tied to hardware and what support comes with it.
Retail license
Not tied to a specific PC — you can deactivate it on one machine and reactivate it on another
Comes with direct Microsoft support
Best for anyone who upgrades or rebuilds their PC over time
OEM license
Locked to the first motherboard it's activated on
Typically bundled with new pre-built PCs by the manufacturer
Usually lower cost, but not transferable to a new PC
All the license keys sold in this store are genuine Retail keys, so they aren't locked to a single machine.
