Windows 10: only one core apears

so i have a 2 core 4 thread cpu but today i tried to use xtu to boost gaming performance and then i only saw 1 core active and i thought maybe they parked again but when i tried to unpark them with a program called unpark cpu i could only find 1 then i tried another program called quick cpu and i could also only find 1.

when i went to system information i also only found 1 even in system configuration on the boot tab when i pulled the list of cores down there was only 1 when, just before that there were 4.


if someone could explain that would be awesome.

Windows detects only one core

Hello,

I've been using windows 10 since 2015 and it worked aces until now. Yesterday i installed the latest update and after rebooting i noticed that windows is using only one core of my CPU which is a core i7-4702hq. Device manager shows all the cpu cores, but
in task manager only one is working. I looked the advanced boot option and it only shows one CPU core. I also reinstalled the CPU drivers but nothing changed

I restored the system to before the update but the problem persist.

Note: I use ubuntu in dual boot and i have no problem with it. Ubuntu detects all the CPU cores.

Hope you have a solution for me.

Thanks.

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
