In fact a few processors have seen performance drops of up to 15 percent which is significant enough to be genuinely annoying.
The good news is that the big brains at Microsoft are aware of the problem and are currently working on a fix.
There are tricky hardware requirements needed to run Windows 11. Microsoft has released an updated version of its "PC Health Check" app which will assist users in determining if or whether their hardware is compatible with the new OS.
Based on statistics collected by Microsoft the roll out of Windows 11 will be substantially slower than the Windows 10 roll out was. That is because at present only about half of registered business workstations are even capable of running the new OS.
It's also worth mentioning that as things stand now with the new OS machines with more than 8-core processors may experience performance issues. As with the problems with some AMD chips these issues are currently under investigation as well. Before Windows 11 is formally rolled out there's every reason to believe that those will be resolved.
Windows 10 has been a wildly successful operating system. However just about every longtime Windows user agrees that the menu systems are long overdue for a complete overhaul. That's one of the many issues that Windows 11 addresses.
Microsoft doesn't have a good track record when it comes to making truly innovative software. So don't expect anything groundbreaking from Windows 11. The company will no doubt make a number of excellent incremental improvements and that's not a bad thing at all.
