I moved my Windows installation to a different hard drive, and now I am unable to activate Windows. I had previously changed the processor and graphics card, and added a new hard drive, without encountering any issues.
When using the troubleshooter, I select the option "I changed the hardware on this device recently." After selecting the computer I am using and checking the box, I click "Activate." However, I receive the following message: "We can't reactivate Windows on this device. Please try again later."
By the way, I purchased a retail key from a third party.

2026-10-22T22:16:43.9533333+00:00 I tried re-entering my product key for activation. I had originally installed the version of Windows I purchased onto a 120 GB SSD; however, I am encountering this issue now that I have installed it on a new 2 TB SSD. When I reinstall Windows on the 120 GB SSD, it activates without any problems—but I do not want to use the old SSD.
