1. Start REGEDT32.EXE and locate the following Registry subkey:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon

2. Using your account name and password, double-click the DefaultUserName entry, type your user name, and the click OK. Double-click the DefaultPassword entry, type your password, and then click OK.

Note: The DefaultPassword value may not exist. If it doesn't, from the Edit menu, choose Add Value. In the Value Name field, type: "DefaultPassword" (without the quotation marks). Select REG_SZ for the Data Type. In the String field, type your password. Save your changes.

Also, if no DefaultPassword string is specified, Windows NT automatically changes the value of the AutoAdminLogon key from 1 (true) to 0 (false), thus disabling the AutoAdminLogon feature.

3. From the Edit menu, choose Add Value. Enter AutoAdminLogon in the Value Name field. Select REG_SZ for the Data Type. Enter 1 in the String field. Save your changes.

4. Exit REGEDT32.

5. Click Start, click Shutdown, and then click OK. Turn off your computer.

6. Restart your computer and Windows NT. You should be able to logon automatically.

Note: To bypass the AutoAdminLogon process, and to logon on as a different user, hold down the SHIFT key after a logoff or after a Windows NT restart.

Note that this only applies to the first logon. To enforce this setting for subsequent logoffs, the administrator needs to set:

Key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon
Value: ForceAutoLogon
Type: REG_SZ
Data: 1

It will be somewhat difficult to modify the registry if you can't log on.

If you search you'll find a few programs out there that you can download and copy to a floppy. Boot from it and follow the instructions to reset the password.

Ophcrack can be used to reveal your password. Ophcrack is an open source (GPL license) program that cracks Windows LM hashes using rainbow tables. It can crack 99.9% of alphanumeric passwords of up to 14 characters in usually a few seconds, and at most a few minutes. There is also a LiveCD version which automates the retrieval, decryption, and cracking of passwords from a Windows system.

Starting with version 2.3, Ophcrack also cracks NT hashes.
