Standardně po instalaci Windows Vista je účet Administrator skrytý a zakázaný. Pro povolení účtu je potřeba provést následující:
1. Spustit příkazový řádek jako správce
2. Nastavit heslo: Net user administrator heslo
3. Aktivovat účet: Net user administrator /active:yes
To je vše ...
A. The first thing to do is see if the Administrator account is enabled by going into Safe Mode. I don't think it will be in your case but since this is the easiest fix and only takes a few minutes it's worth trying. If there are no administrative user accounts on the system, the built-in Administrator may become enabled there. To get into Safe Mode, repeatedly tap the F8 key as the computer is starting up. This will get you to the diagnostic menu. Select Safe Mode using the arrow key. If you see an icon for Administrator on the Welcome Screen, click on it. The default password is a blank. Then go to Control Panel>User Accounts and make changes.
B. If you do not see an icon for Administrator on the Welcome Screen in Safe Mode - If you have a Windows 7 installation DVD (not a recovery DVD) you can boot the system with it. Select the default language, then choose "Repair your computer". Then select "Command Prompt". At the command prompt type:
net user administrator /active:yes [enter]
Remove the installation DVD and reboot the system into Regular Mode. You will see an icon for Administrator on the Welcome Screen.
If you don't have a Vista installation DVD (only have a recovery disc) you can make a bootable Repair DVD from the file at this link:

Note: All the Neosmart recovery disc downloads are torrent files. There is a good explanation of torrent files at the Neosmart website. You will need a torrent client such as muTorrent to get the files. The torrent client will download the .iso file with which to create the bootable DVD. You will need third-party burning software such as Nero, Roxio, or the free ImgBurn (http://www.imgburn.com ) to burn the .iso if you are doing this on an XP or Vista computer. Windows 7 can burn .isos natively. Burn as an image, not as data.
C. Disabling the built-in Administrator again - Once you have fixed things, log into the extra administrative account you will make per the suggestions below and disable the built-in Administrator account again for security purposes:
Start Orb>Search box>type: cmd
When cmd appears in Results above, right-click it and choose "Run as administrator" [OK]. Now you will get the command prompt. At the command prompt type:
net user administrator /active:no [enter]
Exit the command prompt.
General Recommendations For Setting Up Users In Windows 7:
You absolutely do not want to have only one user account. Like XP and all other modern operating systems, Vista is a multi-user operating system with built-in system accounts such as Administrator, Default, All Users, and Guest. These accounts should be left alone as they are part of the operating system structure.
You particularly don't want only one user account with administrative privileges on Vista because the built-in Administrator account (normally only used in emergencies) is disabled by default. If you're running as Administrator for your daily work and that account gets corrupted, things will be Difficult. It isn't impossible to activate the built-in Administrator to rescue things, but it will require third-party tools and working outside the operating system.
The user account that is for your daily work should be a Standard user, with the extra administrative user (call it something like "CompAdmin" or "Tech" or the like) only there for elevation purposes. Running as a Standard user is best practice for security purposes and will help protect your computer from infection. After you create "CompAdmin", log into it and change your regular user account to Standard. Then log back into your regular account.
If you want to go directly to the Desktop and skip the Welcome Screen with the icons of user accounts, you can do this:
Start Orb>Search box>type: netplwiz [enter]
Click on Continue (or supply an administrator's password) when prompted by UAC
Uncheck the option "Users must enter a user name and password to use this computer". Select a user account to automatically log on by clicking on the desired account to highlight it and then hit OK. Enter the correct password for that user account (if there is one) when prompted. Leave it blank if there is no password (null).
In your case, if your computer was set to automatically log into a user account that no longer exists or is unreachable, put a check mark in that box so you can see all the user account icons on the Welcome Screen. If you never set a password, it will be blank.
