In Window's control panel, Accounts, then click on your account, then choose change password, then type in your old password, and leave the new password blank
you would have to set up a user name and not fill in the password when you are setting up the account. then you could just hit okay when the dialog popped up.
If it's WinXP, the pw prompt won't show up if you only have an Admin acct and Guest acct. You can also use PowerToy for windows to auto login/enter pw for you.
Bad idea. VERY bad idea. Having blank passwords is like screwing without a condom. You'r probably OK for a while but its going to come back to bite you in the long run.
This PowerToy gives you access to system settings that are not exposed in the Windows XP default user interface, including mouse settings, Explorer settings, taskbar settings, and more.
There is an auto login feature in the list of tweaks and all you have to do is fill out your user name and password and you are set from there on out it will auto log you into windows everytime. Its a way more secure method while still allowing an easy login method.
