[SOLVED] Can't access Screensaver Settings

[Adamsavage79]

For whatever reason, Windows 10 claims it can't find rundll32.exe or that I might not have permission to access it, when I attempt to access the screensaver settings. I checked to see if the file was there, and it is indeed present. This is a new install and I'm currently on KB4507453 (OS Build 18362.239). Suggestions ? I typically just turn off my monitor manually, but it would be nice to have a screensaver.

I fixed it. Changed the value of "EnableLUA" from 1 to 0.

Got my answer from here: [Win10] rundll32.exe "Windows cannot access the specified device..." Error message when trying to open settings

It is odd that User Account Control (UAC) would block the screensaver options. Removing the notification is dangerous since it circumvents the security of the system. By setting that value to 0, or FALSE, the system is more vulnerable to malware and other attacks: EnableLUA

EnableLUA specifies whether Windows User Account Controls (UAC) notifies the user when programs try to make changes to the computer. UAC was formerly known as Limited User Account (LUA).

Values

true	Windows notifies the user when programs try to make changes to the computer. This is the default value.
false	Windows does not notify the user when programs try to install software or make changes to the computer. We do not recommend using this setting, but it can be selected for systems that use programs that are not certified for Windows 8, Windows Server 2012, Windows 7 or Windows Server 2008 R2 because they do not support UAC.

I suspect that your rundll32.exe path was not set up with the correct permissions for normal user access. We can help you fix your file permissions safely to provide the proper security to your system if you are interested.

Sure. How complicated would it be ?

Shouldn't be too complicated. We would need a little information from you to start.

Run msinfo32
Open an instance of elevated Windows PowerShell:

1. Log on to your Windows 10 computer using any account of your preference.
2. Once on the desktop screen, right-click the Start button.
3. From the context menu, click Windows PowerShell (Admin) (a new blue window should appear).
4. Type the following into Windows PowerShell (the blue window):
   

   msinfo32 /nfo "C:\Users\Public\Desktop\msinfo32.nfo"

   (You should find msinfo32.nfo on your desktop when it finishes)
5. Compress/Zip your msinfo32.nfo.

Provide a screenshot of your rundll32.exe permissions

1. Open File Explorer and scroll down in the left pane to This PC
2. Open Local Disk (C:)
3. Open Windows
4. Scroll down to System32 and open System32
5. Scroll down to rundll32.exe and right click on rundll32.exe
6. Click on Properties
7. Open the Security tab
8. Click on Advanced to open the dialog window showing security settings
9. Use the snipping tool to capture a screenshot of the Advanced dialog window
10. Save the image and upload it with the msinfo32.zip file in your next post.

Your image should look similar to this:

I'm guessing you wanted my msinfo zip attached as well ? I didn't both the snipping tool, I always just used print screen and gone into paint.

That was a bit unexpected. Everything looks clean there. Let's try the paths leading up to the application.

Provide a screenshot of your System32 permissions

1. Open File Explorer and scroll down in the left pane to This PC
2. Open Local Disk (C:)
3. Open Windows
4. Scroll down to System32 and right click on System32
5. Click on Properties
6. Open the Security tab
7. Click on Advanced to open the dialog window showing security settings
8. Use print screen and paint as before to provide a screenshot of the Advanced settings
9. Save the image and upload it in your next post.

Provide a screenshot of your Windows permissions

6. Click on Advanced to open the dialog window showing security settings
7. Use print screen and paint as before to provide a screenshot of the Advanced settings
8. Save the image and upload it in your next post.

As Requested. I should add though, that anytime a toolbar or some odd program installed itself on my pc.. It never asked for permission to do so, as it typically piggybacks on the permission of the parent program. I was debating Malwarebytes premium though.
