Microsoft has reconfirmed that users with outdated systems will not be able to upgrade to the new Windows version due to security reasons, among other things.
The AMD Ryzen 2000 series and Intel's 8000 series CPUs are supported (or newer). TMP 2.0 is also required. The high security requirements, according to Microsoft CEO David Weston, should result in a much more secure system.
“We know it sucks that some aren't going to be eligible for Windows 11, but the great thing to remember is the reason we're doing [this] is to keep devices more productive and [ensure that they have] security than ever before so they can stay protected in this new workforce,”
“Group policy will not enable you to get around the hardware enforcement for Windows 11. We will block you from upgrading your device to an unsupported state since we really want to make sure that your devices stay supported and secure,”
Microsoft announced shortly after the release of the system requirements that it is still reviewing the possibility of supporting Ryzen and Intel 7000 processors from the first generation. No new information has been provided in this area by the developer.
