Is OEM key reusable?

OEM keys are used by manufacturers to activate a new PC. They're intended for just one computer only, so they're tied to the hardware of the system (usually the motherboard) that the key is used on.

You might know your version of Windows (i.e., Windows Home or Windows Pro), and hopefully you knew how to get Windows for cheap or even free, but do you know if it’s a retail, OEM, or volume license? That distinction affects your ability to move the key to a different computer. Retail keys are the most flexible type of license. You’re allowed to reuse such a key on different computers. (However, you can’t use a single license on multiple computers simultaneously.) So if you build a whole new PC, you can move the license over to it with no hassle. PROMOTION Upgrade to Windows 10 Pro for $69.99, then Upgrade to 11 Pro for Free Right now in our PCWorld Software store you can buy a Windows 10 Pro license for just $69.99, 65% off its typical price of $199.99. Once installed, you can upgrade to Windows 11 Pro for free. Jump over to our store and start upgrading. Upgrade to Pro for $69.99 OEM keys are used by manufacturers to activate a new PC. They’re intended for just one computer only, so they’re tied to the hardware of the system (usually the motherboard) that the key is used on. Volume keys are licenses purchased by entities like governments, schools, and corporations. An IT administrator determines which machines have an active license.

This PC has a retail license for Windows 10. PCWorld

The quickest way to find out your license type is by opening the Command Prompt in Windows 10 or 11, then entering slmgr.vbs /dlv . To bring up the Command Prompt, just click the Start button, type “command prompt,” and hit enter. After a moment, a screen will appear that says which channel your license belongs to. By the way—despite OEM license restrictions, you can actually reactivate an OEM key on changed hardware. This option is primarily meant for people whose hardware has unexpectedly bit the dust, and a replacement has been swapped in. People who’ve tied the key to a Microsoft account will have the smoothest experience doing this, but you can also use the product key as well.

How do I know what keycaps will fit?

Find keycaps that fit and join a group buy with these steps: Identify your keyboard layout and any nonstandard keycap sizes. Inspect your switches and their stem / mount compatibility. Ensure kit coverage and keycap shape (row profile) across each row of keys. More items... •

If you’re not ready for a deep dive, it’s OK. Community projects have separate pages for announcements, questions, and feedback. You can visit those group buy pages (via links on Kono product pages under the details heading or directly) to ask about coverage for your keyboard. You might even see a reply from the set designer! That said, you should know how keycaps are measured. Manufacturers and designers use “units” to determine keycap size. 1u is typically the horizontal width of an alpha key, like H or Up. Standard spacebars are 6.25u or 6.25 H keys lined up in a row.
