Unable to Access Local Disks (C:) and (D:)


I am currently unable to access my Local Disks, or open programs inside them, such as the task manager, user account control, and even the registry editor. Attempting to open anything (With administrator priveleges) just result in an access denied message. I have tried multiple solutions off the first searches on google, though none of them have worked, due to the things required in those solutions not being able to be accessed.
I have even tried to reset my PC and reinstall Windows, though when I click the "Get Started" button, nothing happens.
Is there any hope left for me, or do I need to get new drivers and abandon my valuable data?

Can you give us a couple of examples of the steps you are doing up until the point you don't get access? It's a bit odd the way you describe it. Of course you have backups for your valuable data I hope.

First of all, don't panic. Connect your disk to another computer and backup any data you want. Then try loading Windows in Safe Mode and update the chipsets drivers. To enter Safe Mode, you have to load Windows 2-3 times and reset your computer before it fully loads. Eventually you will see the troubleshooting screen where you can select Advanced startup options and then Safe Mode. Worst case, some malware blocked access to your disk, you may need to format it and reinstall Windows 10 clean.

Here's a couple of examples -

The one on the left occurs when I try to just open the disks. The one on the right are examples of me using command prompt to modify the user account controls of the disks.

Hi,

Download and install subinacl.msi

Copy and paste this into a textfile (notepad) and rename it to acl.bat.
Execute with admin rights.
Reboot when finished.

@echo off
title Resetting ACLs...
cd /d "%ProgramFiles(x86)%Windows Resource KitsTools"
echo.
echo Resetting ACLs...
echo (this may take several minutes to complete)
echo.
echo ==========================================================================
echo.
echo System Drive...
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
echo.
echo.
echo Windows Directory...
subinacl /subdirectories %windir%*.* /grant=administrators=f /grant=system=f
echo.
echo.

echo FINISHED.

echo Press any key to exit . . .
pause >NUL

Cheers,

I've tried installing subinacl.msi, but when I open the installer, this message appears:

Is there any other way?

Hi,

Worst case, some malware blocked access to your disk, you may need to format it and reinstall Windows 10 clean.
Guess that point is reached by now......

Cheers,

Sorry to bring you the bad news, but yes, some malware really screwed Windows. You have to access your disk from another computer to backup your files and then format it and install Windows 10 again. If you see a message about access rights in your user folder, click OK and it should then open. If not, you may have to take ownership and then set full access to administrators group. Post again to give you details.

Welp. Reformatting time.
