Is there a limit to the piracy system upgrade Win10?

It is true that Microsoft officials have confirmed that pirated Windows systems can be upgraded to Windows 10 for free, but Microsoft also said that computers pirated on Windows 7 and Windows 8.1 systems are still in non-genuine status after upgrading to Windows 10, and Microsoft will not provide support. . Because the non-genuine Windows system is not released by Microsoft, it is not properly licensed or supported by Microsoft or a trusted partner. In addition, when the pirate system is upgraded to Windows 10 for free, 30 days after the expiration, you will continue to receive reminders that your Windows is not genuine, until your Windows system version becomes genuine. In addition, in order to show this information more clearly, your computer desktop may be black. You can reset it, but every 60 minutes, it will re-blackout until the problem is resolved. Therefore, although it can be upgraded free of charge, it is recommended that the landlord should try to support the genuine system better if conditions permit.
