How
to edit the Windows NT Registry.
The Windows NT Registry Editor is REGEDT32.exe and is located in
the %windir%\system32 sub-directory. By default, no icon is placed
on your desktop. You can use explorer to drill down to this file,
right click, and create a shortcut. (This will be at the bottom
of the current window). Cut this shortcut and past it in your windir%\profiles\UserId\Start
Menu\Programs\Administrative Tools. Until you become comfortable
with registry navigation and editing, consider setting options/read_only
to prevent accidental modification. Click on Window/Cascade to display
the 5 panes available. 99% of all your registry activities will
use the HKEY_LOCAL_MACHINE pane and the HKEY_USERS pane. I suggest
that you open the registry help and become familiar with the terminology,
navigation and editing tools. Spend enough time navigating in read-only
mode so you become comfortable.
You might want to get into the habit of creating a new ERD (Emergency
Repair Disk) by running RDISK.EXE /S before making registry changes.
I keep about 5 generations of the ERD. I also use ConfigSafe ( $35
) to make frequent snapshots of the registry before and after making
changes. I use this tool to track changes caused by new installs
and configuration options (and to restore a snapshot if I or an
install mess up) .
Heed the Microsoft warning about registry manipulation. DO NOT BECOME
CASUAL AS YOU BECOME FAMILIAR.
Freeware WinNT tools.
About once a quarter, Microsoft releases a SP (Service Pack). Service
Packs contain bug fixes and enhancements. Service Packs are version
specific; i.e. SP1 for NT 4.0 should not be applied to NT 3.51.
Service Packs are cumulative, SP2 for NT 4.0 contains the fixes
in SP1 for NT 4.0. Besides the executable for your platform (Intel,
Alpha, Power PC, etc..), symbol files are often available. These
are intended for developers who use debugging tools and should not
be downloaded. From time to time, pre and post Service Pack files
called HOTFIXES are posted to correct a problem that can not wait
for the next Service Pack. You may download the Service Packs and
hot fixes from Microsoft's FTP site. Always read all the README
info available!
Visit the Microsoft web site for new drivers, patches, and to use
the support wizards.
While at the Microsoft web site, download the PowerToys listed for
Windows NT (NT 4.0 and greater). Make sure you get TweakUI.
There are lots a freeware enhancements and additions such as the
Distributed File System so spend some time exploring this site.
Bypassing the WinNT logon
prompt.
If you want to autolog a user, both TweakUI and the Resource Kit
utility AUTOLOG.EXE will do it for you. To configure this using
the registry, edit:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Set the DefaultDomainName, DefaultPassword (must be non-blank),
and DefaultUserName. Set AutoAdminLogon to 1 (all are type REG_SZ).
If you ever want to logon as a different user, hold down the shift
key as you logoff.
Turn off CD AutoRun.
Set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom\Autorun,
a type REG_DWORD, to zero. Setting it to 1 turns it on.
Hide that minimized app
from the taskbar.
If you would like to hide certain minimized apps, so they don't
appear on the taskbar, download hideit. I found this freeware app
while browsing the net.
Increase network performance.
If you increase the number of buffers that the redirector reservers
for network performance, it may increase your network throughput.
Each extra execution thread that you configure will take 1k of additional
nonpaged pool memory, but only if your applications actually use
them. To configure additional buffers and threads, edit:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Services\LanmanWorkstation\Parameters
Modify or Add Value of type REG_DWORD for:
MaxCmds The range is 0 - 255 and the default is 15
MaxThreads Set it to the same value as MaxCmds
You may also want to increase the value of MaxCollectionCount. This
REG_DWORD is the buffer for character-mode named pipes writes. The
default is 16 and the range is 0 - 65535.
Adding "open with xyz" to every Explorer right click.
You can add an new option to every right click by editing the Registry
at HKEY_CLASSES_ROOT\* and Adding Value EditFlags of type REG_BINARY.
With the Hex button checked, enter 02000000.
In Explorer select view/options/File Types. Highlight the * entry
and click the Edit button. Click the New button. In the "Action"
box, type "open with xyz". In the "Application ..." box, browse
to the program you wish to use. OK/Close out of the dialogue boxes.
Now, when you right click in explorer, you will always be able to
"open with xyz".
To restrict this functionality to Unknown file types, perform the
Registry edit on HKEY_CLASSES_ROOT\Unknown instead.
To undo this change:
Use regedt32.exe to navigate to HKEY_CLASSES_ROOT\*\Shell. In the
right hand pane, delete the data value from the entry.
Then navigate to HKEY_CLASSES_ROOT\*\ShellEx and delete any Value
Names.
