How to fix the error

Before proceeding, I recommend to perform a simple reboot of your computer or a laptop, and in the case of Windows 10, it is the "Reboot" item, and not to complete the work followed by inclusion.

Simple ways of solving "access is prohibited" in the NVIDIA control panel

If the previous method did not work, the next simple option is to do the NVIDIA Control Panel application:

1. If you have Windows 10, then go to the parameters - applications, find the NVIDIA Control Panel in the list "Applications and Features" list, click on the application and in the "Advanced Settings" section Try using the "Fix" and "Reset" buttons to reset the application. You can also try the launch of the NVIDIA control panel on behalf of the administrator: we find the application in the Start menu, the right click is additionally started on behalf of the administrator.

   

2. In previous versions of Windows, try moving into C: \ Program Files \ Nvidia Corporation \ Control Panel Client and launch nvcplui.exe. On behalf of the administrator (how to start the game or program on behalf of the administrator).
3. Go to the folder C: \ ProgramData \ Nvidia Corporation \ (You can enter the path to the address string of the conductor and press ENTER), then right-click on the folder DRS. and select "Properties". Check if there are available previous versions of this folder on the Previous Version tab, if any - restore the previous version.
4. If it does not help, open the folder DRS. , Select files in it, the names of which begin with NVDRS And have an extension .bin. . Move these files to another location (do not rush to delete), and then restart the computer.

   

5. In Windows 10, you can also try to delete the NVIDIA Control Panel application (parameters - applications and features), and then set it from the Microsoft Store again.

   

Additional methods

Further actions are related to the NVIDIA video card drivers and can also work with the problem under consideration:

1. In case the problem arose after updating the NVIDIA driver, try roll back: go to the Device Manager ( Win + R. — Devmgmt.msc. ), open the properties of the NVIDIA GeForce video card, and if the button "Run" on the Driver tab, use it.
2. Try to download the drivers of your NVIDIA video card from the site. Nvidia.ru. Or from the manufacturer's website of the laptop (the first option is preferable), and after starting the installer, select the "Selecting Installation" item, and then check the Pure Installation item. After the installation is complete, restart the computer and check if the "Access is prohibited is prohibited. Could not apply the selected settings to the system. "

   

3. Try using the system recovery points on the date when the problems did not show ourselves: it will restore, including NVIDIA drivers and related graphics parameters in the registry. Read more: Windows 10 recovery points.
4. With caution (the image may not appear before rebooting the computer): Delete the NVIDIA video card in the device manager, and then in the Action menu update the equipment configuration.

And a few more points that are not drivers, but perhaps able to restore the performance of the NVIDIA control panel settings:

• According to some users, in their case, the system disk checks the system disk using CHKDSK: Run the command prompt on behalf of the administrator, enter the command CHKDSK C: / F And press ENTER, and after completing the process, check whether the situation has changed.
• Theoretically, third-party programs, such as antiviruses or memory cleaning tools, can also cause the appearance of the "access is prohibited". If something like this was recently installed, try to disable or remove such software.
• Try checking the integrity of Windows system files.
