Windows 10: Windows 10 Access Denied - unable to gain administrator privileges

Windows 10 boots however access is denied on all drives. I have tried taking ownership however since access is denied I cannot do this. I can go in and look at security settings, but changing ownership is not possible. C drive usage and free is 0 however I can see the files sitting on This PC in File Explorer. The files cannot be opened, because access is denied.

Windows access denied

Accidentally I denied all access to all users including administrator in all local disk. Now I am unable to gain access. Tried to change owner , but it shows 'can't open access control. Plz help me solve the issue.

Win 10--Access denied

I am unable to save documents in either Word or Word Perfect. I get a message that "Access is denied. You do not have administrator privileges." This is a private computer and I am the administrator and only user. Is there any hope of correcting this "bug"
in Win 10 or should I go back to Win 7 with all of it's warts.

 

Welcome to the forum. Are you logged in as admin? Do programs run ok? Is it all folders or just some effected?

 

It is my son's computer. He is the administrator so he can log in. However the programs do not run and there is no access to any folders. When using command prompt it gives a system 5 error. It does not seem to recognize him as the administrator anymore even though in settings he is listed as the administrator. I am unable to use an elevated command prompt because access to this is denied.

 

I assume it work ok at some point so what has he done to casue it as its quicker if we know how he did it is there no other admin account?

 

He said he downloaded Revit Autocad a couple of nights ago, however I cannot see this in the Add/Remove programs area. Then he downloaded FileASSASSIN from Malwarebytes. The last download was Terraria which looks like a game program. Of course I cannot add or remove any programs now. He said his computer was working fine up until he went to use it yesterday morning.

 

There is no other admin user.

 

See if you can get the built in admin Enable or Disable Elevated Administrator account in Windows 10 Windows 10 User Accounts Tutorials

 

The tutorial instructs that the elevated command prompt has to be used to enable elevated administrator account. I cannot access the elevated commend prompt.

 

That's Option One, you'll need to use Option Four in the tutorial.

 

Yes I agree however unfortunately there is no installation USB or recovery drive.

 

Then you need to create one:

It sounds like something is very corrupted on the hard drive and it is probably going to take a clean install to fix.

 

You can do it without one. See the Tip in Option Four...

Which basically says: turn on, kill the power before it finishes booting. Repeat a few times until it boots into advanced repair mode. From there you can get to a command prompt.

 

Thanks for that Bree. I have not yet tried Option Six to get to the elevated command prompt. When I was working with the computer yesterday I did interrupt Start Up and use the Recovery options (which would not work) but none of them brought me to the screen in Option 6. That is probably because I did not turn it off and on a few times.

The computer is now en route to our tech guy, but if I can halt the process I will try Option 6.
