Windows 10: Win 10 Pro not utilizing both cpu's in a 2 cpu computer

I have a Dell Precision T3500 with 2 Xenon processors. A graphics program I use needs intense cpu use. I have determined that only one of the cpu's is being utilized. Checking the forums, I see that for Win 10 to use both cpu's I need to have Win 10 Pro. I have the pro version, and I'm still only&n

Win 10 BSOD after reducing number of CPUs

• Win 10 x64 running in VMware Fusion VM on MacBook Pro w/ 6 physical cores & HT.
• When VM is configured with 5+ CPUs, Windows runs fine.
• When VM is configured with 4 or fewer, BSOD INVALID SYSTEM CONFIG INFO
  • WINLOAD.EFI missing or corrupted
  • Attempt to repair using ISO image fails

OS X 10.15.4, VMware Fusion Pro 11.5.3

Win 10 Enterprise

Version 1703

Build 15063.2108

Any suggestions appreciated, as I need to move this VM to another HW config with fewer physical CPUs.

Thanks!

 

CPU utilization >100%

I recently upgraded from Windows 8.1 to 10, and discovered a weird problem when opening task manager where CPU utilization was always at 100%. I did a clean install of Windows 10 to make sure it wasn't application specific, but still the same problem.

This problem is very strange because utilization doesn't seem to be tied to a specific process- it just always seems to add up to 100%. Resource monitor actually shows CPU Usage to be in the million%, which is definitely wrong. No performance degradation,
CPU temps are very normal, and even third-party programs such as Speedfan and CoreTemp are reporting negligible CPU usage (1%-2% idle).

I have tried disabling all startup applications, doing sfc /scannow, viewing reliability history, and restarting multiple times. No luck

 

CPU won't go above 23% utilization

I have a custom built PC. specs are below. After some recent problems and a full windows reinstall it seems that my CPU won't go above 23% utilization. I have set the power plan to high performance and am using Prime95 to attempt to stress the CPU. When
I look in the BIOS everything looks correct. The CPU temp is reasonable, it detects the CPU as 3.4ghz. Windows also detects that the model of the CPU is correct and lists it as 3.4ghz in system properties. When viewing the CPU on the performance tab of
task manager is lists the speed as 0.78 GHz and that number never changes. It's like it's stuck on that number. Any help on how to troubleshoot this problem would be appreciated!

CPU: Core I7-6700 @ 3.4ghz

Motherboard: Gigabyte GA-H170M-DS3H

Bios Version: F22e (latest)

Graphics: Onboard Intel 530

RAM: 16gb DDR4 2133

PSU: 550w

Power plan: High performance

Edit:

Additional Troubleshooting steps:

Reset BIOS to default values - Issue still occurs.
