Solved Win7 lost access to main C drive

Specs: Windows 7, 2.793 GHz / 1022 MB
I have recently purchased a new PC with Win7 64 bit Home Premium. During my efforts to come to grips with it all after 8 yrs of WinxP, I have managed to delete my Administrator permissions to access C drive, to download my favorite app's to a folder of my choice etc, etc. I have searched the internet for adjustments to permissions and ownership to no avail.

I think I have somehow blocked my Administrator permissions without allowing Administrator permissions to any other group or person ?

Does that make sense? I hope so, because right now I am stumped with a new PC that I cant access the main HDD of.

Is this solvable?

✔ Best Answer
Open a command prompt with admin privileges and give the following command:

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

Restart your computer.

Can you access C: drive now ?

If this does not work, open a command prompt with admin privileges and give the following command

net user administrator /active:yes

Log off. Now you will see a real, built-in Administrator account along with other accounts. That account has no password and should not be used for daily work.

Now can you access C: drive ?

If yes, create a new user account with admin rights and make the real administrator account hidden again by using the /active:no switch in the above command.

If not, please advise. You may also like to read this tutorial for future use.

Way Out CoolGuy !!

Thanks for your response. I have been studying the CMD tool and it's relevant commands and while I managed to use some of them I am not confident enough to trust myself with the tool.

Any way, I managed to get in with a new Admin A/c and deal with the problem. Many things were still not right, but I was then able to create a Repair Disc and then do a so called "clean re-install" and got it all back to normal, as new. I have only just registered with M'soft as well with 3 days to go!

I offer my humble apologies for not getting back to you sooner than this. You cool computer champs deserve better treatment than that, so sorry AND grateful.

Best regards, David aka fairwind
