Discussing Windows activation issues
Discussing Windows activation issues
I purchased my PC several years back with Windows 10 and a physical activation key. After upgrading, I replaced most components except the SSD, HDD, and graphics card. I performed a fresh Windows installation, verified the activation linked to my Microsoft account, and faced no problems during reactivation. When I switched to Windows 11, I didn’t reinstall and still experienced no issues. Later, my HDD failed, prompting a fresh Windows 11 install on the SSD without complications. Recently, I wanted to run Home Assistant on my old PC parts, so I replaced the SSD with a new one for the main system and intended to use the old drive for a HA setup. While installing Windows 11 on the new SSD, I logged into my Microsoft account but encountered an activation error after installation, even after restarting, updating, and reinstalling. Windows refused activation using the digital license tied to my account. After troubleshooting—restarting, checking updates, and performing a full reinstall—I still faced the same issue. When I booted from the old SSD, Windows worked perfectly and the previous installation stayed active. I discovered the original physical key was still valid for activation. Now I’m confused: both installations appear to be linked to my Microsoft account. Do both versions remain active? Should I retain the old install and run Home Assistant via VirtualBox?
You're covered for a single Windows installation. If you're using just one computer at a time, it's a gray area, but the safest choice is to purchase an additional license so both devices are authorized.
I don’t really need two Windows PCs at first. I was planning to use HA OS or possibly Linux, but after seeing the activation details I wasn’t sure. If it looks incorrect, maybe you should wipe one of the drives. Which version of Windows would you prefer to get rid of?
Keep Windows active on your primary PC, install a Linux environment or another OS on your home server.
I think the digital license was meant to link your hardware to Microsoft registration, so the motherboard would turn on automatically after Windows installation. However, because Windows 7/8 keys are now deactivated, I’m uncertain about the current process. I doubt the physical key will support multiple installations anymore—previously one key could handle several setups. This isn’t about license validity but whether the key actually worked during activation.
There seems to be a challenge with transferring the digital license from the old drive to the new one. The installation method still requires the physical key, which isn’t ideal since you prefer a different setup. You might need to explore alternative activation options or contact support for further assistance.
It seems the physical key you used earlier might not be valid for future activation. I’m not certain if OEM keys can be reused more than once, so double-checking the details is important.
Using a tangible key to start Windows 10 or 11 converts it into a digital version, rendering the physical key useless. The digital key becomes linked to your Microsoft account (or you can generate one later and sign in with it). Within your account, you can detach the license from one device and reattach it to another.
