Windows 10 isn't reaching the activation server
You're facing issues activating Windows 10 Pro, even though your other devices work. The activation server connection problem might be the main cause. You have two valid keys, so you likely just need to re-enter them correctly or ensure your device is properly connected. If the issue persists, consider checking your internet connection, restarting your PC, or contacting Microsoft support for further assistance.
You meant to ask about what it means to test them, since some keys only function once and you used a method to activate something that might stop working later. It depends on the key—make sure both work and your computer has internet access, wired or wireless.
I tested them on my desktop first, but they didn’t work there. I moved them to my laptop and they functioned properly. I reverted the codes back to my laptop’s settings. Once connected to the PC, I used other online tools to assist activation. The internet remained stable throughout.
What kind of key do you possess? KMS keys depend on a KMS server, which is essential for proper operation. If no such server exists, it may lead to similar complications. You can test by running slmgr -dli on your system to check the results. RETAIL keys are typically used for 1-1 setups. KMS works best when integrated into an IT infrastructure.
