OEM limitations can restrict customization and flexibility in product design.

The OEM model matches a standard version, though I can't confirm if the key is tied to my motherboard. The main concern is how often I replace my motherboard.
OEM license targets system constructors. The goal is to cut costs and boost profits or lower the price for end users. This means the license is linked to your specific motherboard. A special rule applies: if your board fails and you can't replace it, and you must swap the board (which may require changing the CPU and other parts), you can activate it only under these circumstances—phone activation required. This applies only to that exact system. The Windows OEM license is also non-transferable; you can’t resell or give it away alone—it must stay with the original setup. There’s no technical support from Microsoft if you need it, which is something few actually use. Retail licenses offer full support, transferability, and resale options, as long as they remain installed on a single system. Many prefer OEM because upgrading often means switching to a newer Windows version.
I've installed my copy of OEM Windows 7 and 8.1 on multiple builds (not simultaneously, I mean when I swap out hardware or transfer to another build entirely). Most that's happened is you have to go through the automated Microsoft phone activation, which is no big deal at all. It's worked every time. Also, no tech support from Microsoft, but if you're building a machine for yourself, chances are you can figure out what is going wrong if anything does go wrong.
I've applied my Vista OEM key on three different motherboards, including a laptop. My current Win7 key works on its third board as well—initially a Gigabyte P67 RMA due to the Sandybridge SATA issue, then later swapping in the replacement Gigabyte P67 B3 with my present MSI Z77A. Frequent changes (motherboard swaps plus HDD adjustments) often cause activation failures. The automated phone support has repeatedly helped resolve these issues. Overall, the retail version is more user-friendly and offers better tech assistance.
It doesn’t imply you’re allowed to do this without getting caught. Unless the hardware had prior issues, changing your Windows licenses would be a violation.
Indeed. On my Win7 it's a grey area. The first swap was due to a faulty motherboard (the C:\ drive kept disconnecting from Windows Explorer), the second one was a motherboard upgrade due to a pair of broken USB ports. Both boards were technically still working, although they had problems (quite major ones in the first case). The Vista swap to a laptop on the other hand ... but that was a loooong time ago and I only used that number because I couldn't read the one on the laptop itself anymore. Wasn't going to sell it with Linux on it.
Not using OEM on many devices
I've installed OEM versions on various systems
You're not allowed to do this. It violates the Windows OEM license terms you accepted. This doesn't guarantee it will function for you—just mention it and try to cancel licenses. Your actions, unless your earlier versions are faulty, have invalidated your license.
