You will need another computer to run Lazesoft Recover Windows Password. Create a bootable CD or USB flash drive. You may need to disable SecureBoot and Quickboot/Fastboot in your UEFI settings. Home edition is free.


Boot Lazesoft and enable the Adminstrator Account.




After unblocking the Adminsitrator Password you should be able to login to the Adminstrator Account and back out of your changes.

Welcome to Bleeping Computer.


Let me guess, you used the Deny permission.  You should be able to take ownership of the drive and work the rest of it from there.

So what i did: 


- Got into PC repair mode

- Changed the file name of CMD to work on the setch command (tapping shift 5 times)
- Restart

- Got to windows login screen, here i hit the bleep to get the CMD running

- Activated the hidden user account and retreevd password to the other account be using /random. 
- I also used the command "takeown" to add rights to the local administrators group over C://windows/system32

Result: FAIL (fail to take own of C: & D: disk, still locked)

So next i downloaded new OS on another machine and installed it.

Result: Positive 
- Go control over C disk (dah, i just deleted the thing, so  you know, it happend) But antoher thing
- when i had this under control i now could force ownership of D: disk, where i had my files stored. 

So gratz to me and tnx 

Kilroy for comment's. 

    Now i am going to do the same thing once more. Couse im am sure i could get thru without installing new OS, since i had control to the CMD on login and DOS. if you want to taggle along, say hey. tnx again. exuse the english.
