Error: Access denied when try to access C drive.

These people don't know the answers to any of this query. Can not access advanced security setting: IE anything: Device manager, restore point, get it... Anything....

I see my name in settings but they won't highlight when accessed.

Happened after I disabled homegroups to try and use Windows Easy Transfer (my ****)

What a stupid program that is. It wanted permissions to change. Tried everything to allow new computer to transfer files and folders. 

Used original net set up USB I created to get back into original network. Access denied.. Does anyone from Microworst get that this thread has never/ever been solved by anyone for MS.

Access denied: EVERYTHING>>>> includes BOOT MODES, Dos prompts, ETC

Like she suggested above, will probably have to partition the hard drive, buy a Windows 7 CD and reinstall operating system and lose every program and all my files and folders on my laptop.

And as the new manufacture of my new laptop recommended to use Microsoft Easy Transfer to transfer my data. All is lost.

Anyone out there get it????

Hi there. Ironically, had problems logging in to reply, so, created a new MSN account.

I don't mean to state the obvious, but I've tried all the recommended options found on these threads. Also, I'm getting c++ visual runtime error on Windows packages.

I can't get to a restore point. I get this (can you clarify the error code please?)

windows cannot access C:\windows\system32\rstui.exe

When I hit diagnose, I get this:

An error occurred while troubleshoting:

A problem is preventing the troubleshooter from starting

No kidding. I cannot access, or run anything directly connected to the c:drive. I'm taking it to a shop tomorrow to see what they do (probably install a new copy of windows). Any last minute ideas to unlock this infernal machine!? ...

Hi Gary,

You can perform System Restore to go back to previous state when it was working fine:

Note: When you perform System Restore to restore the computer to previous state, programs and updates you installed are removed.

a. Click Start, type system restore in the Start Search box, and then click System Restore in the Programs list. 

If you are prompted for an administrator password or confirmation, type your password or click Continue.

b. In the System Restore dialog box, click Choose a different restore point, and then click Next.

c. In the list of restore points, click a restore point that was created before you began to experience the issue, and then click Next.

d. Click Finish.

Refer: System Restore: frequently asked questions

Hope the information helps.

Hi Debleena.

Yes, I had made changes before this happened. I think it's why it happened (as outlined in original post). I changed some settings for allow/deny and cancelled them halfway through by accident, then became locked out.

I can't do anything related to the drive, including changing ownershiop, it seems.

When I am in advanced security settings for local disk c:, the current owner field has 'unable to display current owner' in it, which is ineditable.

Beneath it, it has change owner to: User (User Pc\User).

What elese can I do? It seems as htough there's no magic switch judging by the amount fo threads this has generated before. Would reinstalling WIndows do it?

Thanks, Gary

Hi,

Have you made any changes on your computer prior to this issue?

Let’s follow these methods & check if the issue persists:
