Official support for Windows 10 will end in October, and Microsoft's Extended Security Support program (ESU) is also being rolled out to users to help users continue to receive security updates.However, this plan is not open to all users, and users in some countries or regions are explicitly prohibited from obtaining ESU licenses.

According to relevant policies of the U.S. government, users in some countries or regions are prohibited from accessing or obtaining ESU licenses. Initially, Microsoft restricted the acquisition of ESU licenses from countries including: Belarus, Russia, North Korea, Cuba, Iran, Syria, Venezuela, and Ukraine.
Recently, Microsoft updated the regional restrictions to remove Ukraine but add Lebanon.Currently restricted countries and regions include: Lebanon, Belarus, Russia, North Korea, Cuba, Iran, Syria and Venezuela.
Users in these restricted countries or regions cannot obtain ESU licenses through normal channels, but they can also obtain licenses through other tools.
Microsoft's ESU program, designed to give Windows 10 users an extra year of security update support, normally costs $30 per device, but in reality, there are several free ways for most users to get a license.
