Registry Tips

Comparing Registries

While working with changes to your system, you might want to see what is changing in your Registry.
Since you can export it to a text file, the steps are fairly easy

1. Start Regedit
2. With the very top level select - My Computer, on the Toolbar select Registry / Export Registry File
3. I usually save it to the root of the C: drive with the name before (you don't need to add an extension)
4. Make the change to your system
5. Go back to Regedit
6. Press F5 to update it
7. Export the Registry like step 2
8. Name the file after and have it go in the same directory
9. Open up a DOS window
10. Go to the directory where the two exported files are
11. Enter FC before.reg after.reg > diff.txt
12. Then you can edit diff.txt with your favorite text editor.

Note: I  do the last steps so often I have a simple batch file already set up.

Simply include a minus sign inside the left bracket before the main key.

For example.
If you want to delete the key HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Office \ 8.0 \ Common \ Assistants, your regfile would simply look like:

[-HKEY_LOCAL_MACHINE\Software\Microsoft\Office\8.0\Common\Assistants]

Automatic Shutdown with Windows NT

Most laptops allow the operating system to turn off the hardware after shutdown, instead of displaying the message telling you it's now safe to turn off your system.
You can take advantage of this capability by enabling the Power Down After Shutdown feature.

To enable this feature, simply add a REG_SZ value named HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\PowerdownAfterShutDown and set it to 1.

Next, tell NT to shut down and see if the machine turns itself off after shutting down. If it doesn't, change the value back to 0 to restore normal operation.

---

Kill Hung Processes When Logging Off in Windows NT

When you tell NT to shut down, it first sends shutdown requests to any running processes.
Most 32-bit applications honor these requests and shut down, but older 16-bit apps running in the Virtual DOS Machine often won't.
When this occurs, the operating system prompts you with a dialog box asking if you want to kill the task, wait for the task to die on its own, or cancel the shutdown.
By modifying the Registry, you can automate this process.

You can force NT to kill all running processes on shutdown by adding a REG_SZ value named HKEY_USER\\ControlPanel\Desktop\AutoEndTasks and set the value to 1. You can also add this value to HKEY_USERS\.DEFAULT so that all new accounts will shut down the same way.

---

NT Crash Log File

In addition to the crash log file, you can also enable two other methods of crash notification and logging.
You can enable an administrative alert by changing the value of

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl\SendAlert to 1. The next time the system crashes, an administrative alert will be sent that may provide the first sign of the crash.

You can also make NT log the crash in the event log by changing the value of

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\CrashControl\LogEvent to 1 instead of its default 0. Now, the exact time of the crash will be permanently recorded.

---

Changing the Location of Outlook Express Data Files

Getting Rid of Schemes

Before you delete them, choose or create at least 1 Scheme and "Save As" (in my case Bud 1).

1. Open Regedit
2. Go to HKEY_CURRENT_USER \ Control Panel \ Appearance \ Schemes
3. Highlight every String and Value on the right side and delete. DO NOT DELETE "Default"

Hiding Any Combination of Drives

If you want to stop a drive or any combination of drives appearing in Explorer/My Computer

Add the Binary Value of 'NoDrives' in the registry at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Give it a value from a combination of the table below:

A 1 00 00 00
B 2 00 00 00
C 4 00 00 00
D 8 00 00 00
E 16 00 00 00
F 32 00 00 00
G 64 00 00 00
H 128 00 00 00
I 00 1 00 00
J 00 2 00 00
K 00 4 00 00
L 00 8 00 00
M 00 16 00 00
N 00 32 00 00
O 00 64 00 00
P 00 128 00 00
Q 00 00 1 00
R 00 00 2 00
S 00 00 4 00
T 00 00 8 00
U 00 00 16 00
V 00 00 32 00
W 00 00 64 00
X 00 00 128 00
Y 00 00 00 1
Z 00 00 00 2

Where (for eg) you want to hide Drives {C,E,J,O,R,U,Y,Z} you would give 'NoDrives' the value 14 42 12 03
Where C+E = 14, J+O = 42, R+U=12 and Y+Z = 03
Please NOTE: The Numbers are to be added in HEXadecimal ie: ABCD = 0F, not 15 All Drives Visible is 00 00 00 00 All Drives Hidden is FF FF FF 03

Now before anyone logs into that computer, this banner will come up on the screen.
This can be useful for any legal warnings you want to give regarding the use of the computer.

Disable Password Caching

As in Windows for Workgroups, when logging on to an NT Domain, it is preferable to disable password caching.
This allows for the single NT Domain login and eliminates the secondary Windows logon screen.
It also eliminates the possibility of the respective passwords to get out of sync.

To disable password caching on the workstation, a one-line addition to the registry needs to be made.
To make the change, create a ASCII text file called DISABLE.REG with the following lines:

  REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network]
"DisablePwdCaching"=dword:00000001

Open up a DOS box and type REGEDIT DISABLE.REG

You can also download the DISABLE.REG file.

If you need to re-enable password caching, download ENABLE.REG and repeat the process just with the different file name

7. For the value of this command, enter the full path and program you want to execute
8. Now when you right click on the Start Button, your new program will show up. You do not need to reboot first.

Fixing Corrupt Registry

If your registry has gotten corrupted, and re-installing Windows95 over your existing version does not fix the problem,
there is a hidden, read-only, system file on the root of your boot drive called SYSTEM.1ST.
This is the initial system registry created when you first installed Windows95.

To use this file:

1. Go to your Windows directory
2. Un-Attrib your current SYSTEM.DAT file (attrib -r -s -h system.dat)
3. Copy your current SYSTEM.DAT to something like SYSTEM.BAD file (just in case)
4. Move to your root directory
5. Un-Attrib the SYSTEM.1ST file
6. Copy SYSTEM.1ST to \WINDOWS\SYSTEM.DAT
7. Re-start your system

You will need to install your 32-bit apps and any other programs or changes that modified your system registry
but you will not need to go through a new again. Your 16-bit apps should not need to be re-installed since they do
not modify the registry. You will also retain your current desktop configuration.

Recycle Bin Edits

Fooling with the recycle bin. Why not make the icon context menu act like other icon context menu's.

Add rename to the menu:
[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:50,01,00,20

Add delete to the menu:
[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:60,01,00,20

Add rename and delete to the menu:
[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:70,01,00,20

Restore the recycle bin to win 95 defaults including un-deleting the icon after deletion:

.. Restore the icon.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Desktop

\NameSpace\{645FF040-5081-101B-9F08-00AA002F954E}]

@="Recycle Bin"
... reset win 95 defaults
. [HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:40,01,00,20

Other edits to the recycle bin icon:
[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:40,01,01,20 ... standard shortcut arrow
"Attributes"=hex:40,01,02,20 ... another shortcut arrow
"Attributes"=hex:40,01,04,20 ... and another shortcut arrow
"Attributes"=hex:40,01,08,20 ... make it look disabled (like it's been cut)

I added the above edits for fun. But it gets you thinking.
Note: Adding rename and delete to the context menu takes effect instantly. To restore the icon after deletion requires screen refresh (F5).
Have fun.... Tom
