<p>Microsoft is currently analyzing the issue that is preventing the activation of Windows 10 and Windows 11. This issue is specifically happening on computers that were upgraded from Windows 7 or Windows 8 to newer versions for free. If users have replaced essential hardware components afterward, like the motherboard, Microsoft may unexpectedly deactivate the Windows 10 or Windows 11 license.</p>

<p>Some affected users claim that they have not replaced hardware but have only performed a BIOS update for their motherboard. It&#8217;s interesting that even this action seems to disable activation on computers that were updated from Windows 7 or Windows 8 to Windows 10 or 11.</p>
<p>And even if customers still have the original activation key from Windows 7 or Windows 8, which is legal and valid, they can no longer reactivate their legally updated Windows 10 or Windows 11 computers.</p>
<p>It&#8217;s worth saying that the affected users have not used any illegal activities; it appears that they are simply facing the consequences of Microsoft&#8217;s decision from September 2023. According to this decision, valid license keys for Windows 7 or Windows 8 can no longer be used to upgrade to Windows 10 or Windows 11. The only free upgrade path now is from Windows 10 to Windows 11.</p>
<p>Microsoft is aware of these complaints but still hasn&#8217;t commented on the issue.</p>
