Unable to turn off Fast Start on Samsung computer

Hello again. I recently upgraded my SENS 900X Samsung laptop from Windows 7 Home Premium to Windows 10. I did the easy upgrade, not a clean install. I did reformat my computer while it was in Windows 7, updated it, then upgraded to Windows 10.

When I turn on or restart my computer, I get a message which says:



I found help with this issue on this forum: link: https://www.tenforums.com/tutorials/4...dows-10-a.html

However, after performing step 3, I get this message: "Your power plan information isn't available. Access is denied."



Help would be awesome! Thank you in advance.

Note: I've found many fixes for users in Windows 7 and 8, but I don't want to start mashing keys in command prompt if it isn't good for 10.

Are you logged into an account with administrator privileges?

Yes, I believe I am. I am the only user for this computer, and only one account set up.

Are you able to select another power plan.

Yes, I can change power plans, and change settings, no problem.

powercfg -h off

I tried, and this is what happened.

Okay, I opened command prompt as an admin:


I am still getting the same message when I try to change what the power buttons do. "Your power plan information isn't available. Access is denied."

There seems to be an issue with just that one power plan then since you are able to change the settings in other power plans without issue.

Is this a custom power plan that is having this issue?

If so, I would recommend to just use another power plan set how you like.

I have changed to the normal, "recommended" power plan, however I still get the Fast Start message saying that the application isn't supported on this version of windows, which is what I am trying to get rid of. I'll try restarting the computer with other power plans to see if this is the cause.
