Although my laptop was working fine a few days ago (although i did trip and drop my laptop and that injured the screen but was easily fixed and i dont think that a physical problem could harm the contents and data of the laptop) it started to act wierd as i wasnt able to delete or modify any files but it seemed to only be things that were related to programs e.g. shortcuts. I found this extremely wierd and had googled for research and tried multiple solutions but when i try to become a admin i am not able to as i dont have enough elevation. In the Advanced Security Settings for Local Disk the current owner is named "TrustedInstaller" and my account is in the "Change owner to" list but when i click the Edit button an error saying "The Requested Operation requires elevation". I cannot even create a repair disk as i need admin rights to do that. Also the Command Prompt says i am a Guest when i use "net user NAME". Help would be appreciated :)

Hi, Try to see if you have the administrator accounts in Windows 7: Press Win+R, type control userpasswords2 into box to check the users in computer. If you forget the administrator password and don't have a password reset disk or another administrator account, you won't be able to reset the password. If there are no other user accounts on the computer, you cannot create a new administrator account.

When i tried that i needed admin powers to access it :\

Well i cant open CMD as administrator as i need admin powers to do that but i did everything else in case. At Step 5 it says "The username could not be found. More help is available by typing NET HELPMSG 2221" and when i type "NET HELPMSG 2221" it says "The username could not be found".

To enable the build-in Administrator account, follow these steps: Built-in Administrator Account - Enable or Disable 1. Click Start, and then type cmd in the Start Search box. 2. In the search results list, right-click Command Prompt, and then click Run as Administrator. 3. When you are prompted by User Account Control, click Continue. 4. At the command prompt, type net user administrator /active:yes, and then press ENTER. 5. Type net user administrator <Password>, and then press ENTER. Note: Please replace the <Password> tag with your password for your administrator account, removing the brackets. 6. Type exit, and then press ENTER. 7. Log off the current user account. To revert do exactly the same thing but change net user administrator /active:yes to net user administrator /active:noPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hi, Try the following steps to check if it works: 1. Repeatedly tap the F8 key when the computer is starting up. 2. Choose "Repair your computer". Then select "Command Prompt". At the command prompt type: net user administrator /active:yes 3. Reboot the computer, and try to see if you can log into the built-in Administrator account.

Hi Jun-ho, on a computer that can access the Internet go to http://pogostick.net/~pnh/ntpasswd/ and download the ISO file and burn it. Boot on this CD and you can clear the administrators password AND unlock the administrator account. This CD is every system administrators best friend and worst enemy, with it you can own ANY Windows PC that you can physically touch, all the way up to Server 2008 R2, I've been there and done that.
