User account type changed from Admin to Guest

[PSz]

I only have one account on my recently installed Windows 8 and accidentally managed to change the account type from Admin to Guest in User Accounts. Now, I am not able to run any programs that require administrator password. The popping up window says "to continue, type an administrator password, then click yes". However, it does not give me any option to enter the administrator password and the button "yes" is disabled (see attachment). Also, at the logon I don't have an option to choose any other account than the one that used to be admin, but is now guest. I feel like I entered a loop, because now I am not able to go back to User Accounts to change it back. Are there any options for me to change the account type back to Admin?

It had all worked fine before but I changed my hotmail password recently and was not able to start Windows 8 without entering the password any more, so I wanted to adapt the password in User Accounts. I did not find that option so left User Accounts (must have then accidentally changed the account type, still not sure how), but since then I am not able to enter it back (since I cannot run any programs as administrator).

Thanks for any help,
Piotr

Hello Piotr, and welcome to Eight Forums.

If you like, you could try refreshing Windows 8 to see if it will set you up another administrator account. You may need to do so at boot. Be sure to back up anything that you do not want to lose first though.

Hope this helps,
Shawn

Hi, here's how:

1. Download Hiren's BootCD 15.2 - All in one Bootable CD » www.hiren.info and burn it to CD/USB
2. Set BIOS to boot from CD/USB then reboot your PC
3. From menu, select Boot Mini XP
4. Double click on the Wrench Tool labeled HBCD Menu->Browse, Search for HBCD Folder->Programs. On the right hand side, look for PasswordRenew and double click on it.
5. On the bottom right corner, click on select A Target and browse to Windows folder (The drive letter might be different), high lite it then click OK
   
   
6. On the Left Hand side, select Turn Existing User to Administrator
   
   
7. Select the 'User' then click Apply

Hope this helps !!!
