Convoluted Story
Convoluted Story
Hey there, this is exactly what I’m facing. I swapped out both hard drives and the motherboard, then installed Windows with my product key. I didn’t erase the old drives or the board. After that, I transferred the old components into a fresh machine and started it up. Windows seems to be running smoothly on both systems. My main concern is why two separate computers can use the same license. I’m not sure what’s actually happening but I’m curious if signing them to the same Microsoft account is enabling this. Thanks for your help!
P.S. When I booted the old machine with the new board and drives, it asked for a new CPU and RAM—though I couldn’t see the details before it disappeared from view.
Windows comes with a license either attached to the computer or linked to your Microsoft account. From Windows’ perspective, you have one installation because it’s installed on a single machine. It uses a special identifier to check if the hardware is the same or different. The main issue that could cause activation problems is changing your motherboard, which would mean your license might not transfer. I updated my note: I just returned from work and almost read your message—sorry about that. Edited November 27, 2017 by Tabs
The agreement is linked to your physical device, especially your motherboard. Your MS accepts only hardware that has been licensed. The Motherboard.
The message explains how activation works with older digital licensing systems. It clarifies that changing hardware can sometimes cause issues if all components are updated, because the system uses device identifiers to generate a unique code. This code depends on various hardware parts, and small changes may not always trigger reactivation. The process was more hardware-dependent before Windows 10 introduced digital entitlement, which allows activation without a product key. For details, refer to Microsoft documentation and a recent news report from zdnet. Much of the information comes from webinars I reviewed recently, but technical specifics are often unclear. You can test changes by comparing activation IDs before and after hardware modifications using tools like slmgr.vbs.
You seem to have some misunderstandings about your license. Based on what you shared, it appears the license is likely a retail version rather than an OEM one. If it were OEM, the license would be tied to the hardware and could only be used once. However, there might be a way to reactivate it when replacing the board—just check with Microsoft. Since it looks like a retail license, you can install it multiple times on up to 10 devices as mentioned by @Tabs. The MS account mainly serves as a visual confirmation that the license was used on a device, helping track usage details like installations and devices. Your license isn’t directly linked to your account, which means it remains valid even if someone activates it without a Microsoft account. Each installation key is connected to the specific motherboard it was installed on.
The first connection I shared (as you mentioned) matches exactly where this adjustment was made. This update was completed in 1607. I’m puzzled why you keep referring to me incorrectly, particularly here where I actually provided the original references. These digital licensing updates were introduced in 1607; prior to this, it was mainly a simple link between your license and your Microsoft account, allowing you to skip manual activation on the same device if you reinstalled. The ability to reactivate on new hardware arrived with the same change in 1607. My mistake—thank you for pointing that out, though I realize I didn’t explain enough in my last message.
I haven't stated your mistake. I overlooked it. The next time I see 1607, I'll look at that source and verify my understanding.
Using the retail version allows installing the license on up to 10 devices, but each key is tied to a specific device. Moving the key from one device to another isn't possible. For example, if you have PCs #1 through #10, you can't transfer the key from #3 to #11. However, upgrading the hardware on device #3 keeps the key functional with the new setup. Regarding the information mentioned, it seems MS enabled linking your license to an MS account for easier recovery via a troubleshooter. A more detailed explanation is being prepared, but I can't provide it right now.
I'm sorry again, my understanding was wrong. Microsoft seems more flexible lately about how Windows activates. They seem to favor having Windows 10 installed widely rather than restricting people from using older versions like Windows 7 or 8.1. Their "unsupported" labels for Kaby Lake, Coffee Lake, and Ryzen likely support this approach. @BabyPCMR You're right, though—this shouldn't be a problem unless you rely heavily on those keys during major upgrades. Over time, constantly switching hardware might eventually stop activation, but changing between 10 different setups is manageable. Small tweaks don't matter much.
