i remove my user account password, but it revert back

[Redsiamesecat]

hello...

sorry for bad english
yesterday i buy ssd for my notebook so i installed windows 7 ultimate 64 bit using file ISO X17-59465....
then i install it,i give the username in the setup as "my name", then when the setup asking for password, lets say i fill it with "qwerty" as my password...
okay my installation is done, when it comes to windows logon it asking for password so i put my password earlier "qwerty" , but it says password incorrect, i dont know what happen but im sure that i didnt put my password wrongly, because its really easy to remember, actually my plan is to change password when i arrive at desktop but i stuck at windows logon, so i restart my notebook and go to safe mode, go to the user account at control panel and remove the password, okay now my password is removed, but i want to make sure so i close the user account windows, then i go to the user account again, but i surprised that my account still have password, i dont know why its still have password , so i remove again, but its revert again...
so i delete that account and make new administrator account,lets say the name of the new admin account is "anon", and that's worked... now i can go pass the windows logon and go to the desktop...
but the name "anon" ,i dont like it cause i just randomly give the name,I want the name that I've used when installing windows, its "my name" ,so i created another administator account and give the name as "my name", but it suddenly have password again, omg i dont know what to do,so i assume the name when i put when installing windows is still stuck with the password....
so how to make the password completely gone ?
im asking this because i've experienced something more unusual, 3 years ago, i reinstalled my windows and install windows 7, that time i didnt put any password, just blank, but when it comes to windows logon it asking password, so i want to know what the cause of this problem..
thx for helping

Delete the strange account totally (when logged on good working account). Reboot (not necessary I think). Strange account is really gone? Remake the account without a password. Works?
Set password on that again

i've already done that, i delete that strange account, yes that strange account is gone, but when i recreate the account with "my name",and suddenly it password protected again, its just strange...

i've tried that too, when i change the password, its says the password changed, so i restart my notebook, and when in windows logon, i put the password that i've already changed, but the password is incorrect again...

Where did you get WIn7? It shouldn't normally perform this way using Genuine Win7 software.

This is also why I never set up a password on my installs, only later when the user really needs and wants it they can set it up in User Accounts.

Make sure you have a perfect baseline install using only the official WIn7 installer ISO with SP1, deleting all partitions during install, following the same steps in Clean Reinstall - Factory OEM Windows 7. If the problem returns then wipe the HD with Diskpart Clean Command before reinstall.
