Disable Windows 10 fast startup.

The instructions for doing that are:
1) Open Power Options:
Press the Windows key to open the Start Menu.
Type in "Power Options" and select it from the search results. Brings up Settings/Power & sleep
2) Choose what the power buttons do:
In the Power Options window, click on "Choose what the power buttons do" on the left sidebar. "Choose what the power buttons do" does not exist
3) Change settings that are currently unavailable:
You might see a note at the top of the window indicating that some settings are currently unavailable. To make changes, click on the "Change settings that are currently unavailable" link. No note of that sort exists. There is no "Change settings that are currently unavailable" link.
4. Disable Fast Startup:
Scroll down to the "Shutdown settings" section. There is no "Shutdown settings" section.
Uncheck the box next to "Turn on fast startup (recommended)". There is no "Turn on fast startup (recommended)" checkbox.
5. Save Changes:
Once you've unchecked the "Turn on fast startup" option, click the "Save changes" button at the bottom of the window. No "Save changes" button
6. Restart Your Computer: You'll need to restart your computer for the changes to take effect.

Are there alternate instructions for a currently up to date Win10?

Determined the CPU and GPU were not at fault... Independently I consulted https://www.supereasy.com/how-to-vie...in-windows-10/ It was quite an education for me.

p.s. Power Options brings up exactly the same Settings/ Power & sleep window as I quoted in Step 1.

I'm still not able to turn off "Fast Startup". Until I can do that I can't follow your advice by posting a new topic.

It looks exactly as it does in the screen shot. " Lock Show in account picture menu" is the furthermost down "power setting".

If this is the problem plaguing my computer, I won't need to rebuild the damn thing. I certainly don't want to replace it with Win11 when Win12 is already in the wings.
