Processor issue only 1 core

lewisM21 -  
Hello, I had a problem when trying to change my number of processors in msconfig. I went to boot, then advanced options, checked the number of processors, and set it to 12, which is my maximum. Later, I reversed the process, and now my PC is super slow, and when I want to select a number of processors, it only offers me 1.

Thank you for helping me.

Configuration: iPad / Safari 11.0

    Hello
    This kind of modification is at best useless, and can cause problems, even crash the PC.
    Open the task manager, performance tab.
    Click on CPU, and post a screenshot

    There are two categories of people: those who divide everything into two categories and the others.

      Hi,
      The capture clearly shows "Number of PROCESSORS" ... not "cores"

      It's completely normal to have only one, since your machine only has a single processor.

      What was the point of changing this setting? Because I don't see any...

      All that's left is to reset the UEFI and maybe reinstall Windows...

      @Judge_DTBut before it used to go up to 12, why not anymore?

      And if I reset it, how do I do that and what will it change on my PC?

      @Judge_DTHi
      Normally, this parameter indicates the number of cores.
      And you shouldn't touch it!!!

      @phil2kWell, that's why I'm asking what the point of touching it was... because I still don't see it there... :-)

      Open a command prompt, in administrator mode.
      Type bcdedit /v , and post the result.

      @lewisM21By unchecking the "number of processors" box and rebooting, what does it do?
    4. lewisM21
      @phil2kWhen I go to msconfig, it is always unchecked, and by rebooting, do you mean restarting the PC?

    I just retrieved my heart, I don’t know how; a big thank you to you

    I will no longer touch something I don’t know. Thank you again

      You are doing well.
      Some had to reinstall Windows.
      The settings of this menu, don’t touch, never.

      hello, is it possible to get the solution because I'm having a bit of a hard time understanding lol... I'm also in the same situation with an AMD Ryzen 5 5700X 8 core, I have 1 core left and before doing msconfig and restarting my PC there were 16 available
