Regedit (command line) won't save changes: How can this be solved?

Hi. My PC won't boot. Therefore I have to use the command prompt to start programs that can fix the problem. A fix is to create a new key in regedit. So, I'm in DOS, I can run regedit, but regedit won't save the changes I make. I want to mention some things:

I understand that command.com may be run with or without elevated rights or privaleges.

1) When I get to the command prompt by way of Windows Recovery Mode, am I running the command interpreter with elevated rights, that is, as an administrator, or not?

2) If one were to run command.com with elevated rights, would that enable regedit to save changes?

3) Can you run command com, with elevated rights, from the command line, when in DOS that is running without elevated rights?

I do know about runas.exe, but will get to that if I have to.

Thanks. Rich

The situation is, that if I start regedit from an elevated prompt, and if that allows regedit to save changes, then my problem would be solved. The theory though behind this (which may or not be correct) is that as far as regedit is concerned, running it from an elevated prompt must be someone with administrator privaledges.

But if that does not work, I think I'd have to run runas.exe.

Hi. The actual problem with boot, is that signing in with my PIN is not available anymore. Not sure why. I'm going thru a list of fixes:

* 1 Delete NGC folder
* 2 Using Registry editor
* 3 Remove and add PIN
* 4 Use "I forgot my PIN" option
* 5 Create a new Administrator account
* 6 Modify TextHooks registry
* 7 Check if CNG Key Isolation is running

I tried 1, using something like file explorer in my BIOS program, but was unable to delete NGC.
I feel sure there is no virus at work.

I've just got my NUC, and made no backups. I feel sure no virus is at work.

I'm not sure what counts as a boot. I do get to a point where I see a picture and when I press Enter I get (now) two Users. For some reason I now see the original user (Has my name) and "New User". I cannot recall personally creating "New User". I cannot enter my PIN if I choose user that has my name, I cannot "Set up my PIN", does not work. With "New User" I prompted to enter a password, but since I cannot recall making "New User" I cannot furnish a password that works. Be nice if there was a generic password I could use.

I did not do anything with regard to:

CNG Key Isolation
User Data services
Text Input Management Service

In this video, i will explain in detail how to edit the Windows registry offline from a Windows Recovery Environment.

Hi. I get to the point of "Unload Hive" but it is greyed out. So, I cannot finish the process. Any ideas why? Is it a permissions thing? I can Export. I can Exit. I am keen on psyching out why I cannot successfuly save a modification to the registry from a Recovery Environment. Rich

Make sure you select the registry key folder you have temporally created for you to have Unload Hive option.
