There are times we forget login password for Windows Vista. There is easy workaround to login Windows Vista without using any password. Start your computer and continuously tap F8 key before Windows Vista screen shows up. You will get a new screen with number of options.
Select ‘Safe mode’ option from the list and press the enter key to continue. You will reach Windows Vista desktop in safe mode (In Safe mode only critical Window files are loaded and don’t be surprised if colors are fudged and internet in not working).
Now using start menu open Control panel and then look for ‘User accounts & family safety’. Now click on ‘change your windows password’ option under user accounts. Click on ‘remove password’ and restart / reboot the computer. Do not press F8 and let the computer boot to desktop screen. Again goto to user accounts and now add new password to your account (& keep note of that password!).

still cannot get passed splash screen to safe mode no matter what option i select
