Chapter 8 Touchscreen 97
Windows NT auto boot
Windows NT normally displays the system logon dialog when started.
Use the following procedure to disable the display of the logon dialog and
automatically start up without user intervention.
1. Run REGEDT32.EXE.
2. Locate the Registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon.
3. Establish your domain name, account name and password, using the
values you normally type when logging on. (More than likely you
will already have the keys “DefaultDomain” and “DefaultUserName”
and will want to add a password to that account - ”DefaultPass-
word”.)
4. To add a “DefaultPassword” value, choose Add Value from the Edit
menu. In the Value name field, type: “DefaultPassword” (without
quotation marks). Select REG_SZ for the Data type. In the String
field, type your password. Save your changes.
5. From the Edit menu, choose Add Value. Enter “AutoAdminLogon”
(without quotation marks) in the Value Name field. Select REG_SZ
for the Data type. Enter 1 in the String field. Save your changes.
6. Exit REGEDT32.
7. Reboot your computer. You should log on automatically.
Using the touchscreen on serial port COM4:
1. Make sure that the serial touchscreen controller is connected to serial
port COM4.
2. Install "Touchscreen Driver for Windows NT" as described above.
Choose the appropriate serial touchscreen controller on COM4 when
running Setup, to allow for a complete driver installation.
3. Run the Windows NT Registry Editor by clicking the Start button.
Click Run, then type “regedit” and press Enter. (c:\winnt\regedit)
