Hey there!
My name is Ravi, and I am an independent advisor. I am happy to help you. :)
I understand how confusing and concerning it can be to get "Access Denied" for the C drive.
You can try this solution.
- Go to safe mode.
- Search for cmd in the search box.
- Right-click on it to run as an administrator
- Type " net user administrator /active:yes
- Restart again
- Then you can log in as an administrator
- Then go for C: > Properties > Security > Edit > Tick all permissions to your user.
To log in safe mode, you can follow these steps:
1). On the Windows sign-in screen, press and hold the Shift key while you select Power >> Restart
2). After your PC restarts to the Choose an option screen, select Troubleshoot >> Advanced options >> Startup Settings >> Restart.
3). After your PC restarts, you'll see a list of options. Select 4 or F4 to start your PC in safe mode. Or if you'll need to use the internet, select 5 or F5 for Safe Mode with Networking.
Feel free to get in touch again if you have any additional questions.
Cheers,
Ravi
