After I upgraded my computer to Windows 11 Pro, I noticed that it is only detecting one CPU. I checked the 'Number of Processors' setting in MSConfig, but it seems to only account for CPU cores rather than physical CPUs. Previously, in earlier Windows versions, all CPUs were recognized automatically. Has anyone else experienced this issue?

What specific system are you running? Generally, most users only have one CPU with several cores and threads. Just curious if you're seeing something different.
Just a reminder, always back up your data before making changes to BIOS or system setup, as it can sometimes lead to data loss. Better safe than sorry!
Are you sure you actually have more than one CPU? You can usually tell if you own something like that, right? Just checking!
The 'Number of Processors' setting in MSConfig is actually a limiter. I suggest turning it off, saving the changes, and rebooting your system to see if that helps.
Have you checked the BIOS? There's often a cores limiter in there that might be affecting what Windows sees.
Make sure you check your BIOS settings first to see if all CPUs are enabled and that multi-processor support is active. It's also a good idea to update your motherboard's chipset drivers, as Windows 11 often requires the latest drivers to detect all processors properly. If that still doesn't work, you might want to run 'msinfo32' to verify that multi-processor support is enabled, or consider doing a repair install of Windows to resolve any OS-level detection issues.
I have an older 'Skulltrail' Intel desktop board with two CPU sockets, the D5400XS model.
