I had Windows 11 running normally for about a year. Around two weeks ago, a relative used an unofficial product key or activation method on the installation. This week, the computer crashed with a blue screen and would no longer boot, so I had to reinstall Windows. A repair shop checked the hardware and did not find an obvious problem. I plan to purchase a legitimate license, but I'm wondering whether the unofficial activation could have caused the crash, or if the timing was probably coincidental.

An invalid or gray-market product key by itself should not cause Windows to blue-screen or stop booting. Microsoft generally handles activation problems by showing licensing notifications or limiting personalization, not by deliberately crashing the system. The failure was more likely caused by a corrupted update, damaged system files, a driver, storage trouble, or another unrelated issue.
The blue-screen stop code and any files in C:WindowsMinidump would normally be needed to identify the cause. Since Windows was reinstalled, the original crash evidence may be gone, which makes diagnosing that particular failure difficult. If it happens again, record the stop code and preserve the dump files before reinstalling.
