Add Open With to all files
You can add "Open With…" to the Right click context menu of all
files.This is great for when you have several programs you want to open
the same file types with. I use three different text editors so I added
it to the ".txt" key.
1. Open RegEdit
3. Add a new Key named "OpenWith" by right clicking the "Shell" Key and
selecting new
4. Set the (Default) to "Op&en With…"
5. Add a new Key named "Command" by right clicking the "OpenWith" Key
and selecting new
6. Set the (Default) to "C:Windowsrundll32.exe
shell32.dll,OpenAs_RunDLL %1", C: being your Windows drive. You must
enter the "OpenAs_RunDLL %1" exactly this way.
Customize the System Tray
You can add your name or anything you like that consists of 8
characters or less. This will replace the AM or PM next to the system
time. But you cannot do this if you are using any of our software
during the trial period; it will corrupt the trial license.
1. Open RegEdit
2. Go to HKEY_CURRENT_USERControl PanelInternational
3. Add two new String values, "s1159" and "s2359"
4. Right click the new value name and modify. Enter anything you like
up to 8 characters.
If you enter two different values when modifying, you can have the
system tray display the two different values in the AM and PM.
LockOut Unwanted Users
Want to keep people from accessing Windows, even as the default user?
If you do not have a domain do not attempt this.
1. Open RegEdit
2. Go to HKEY_LOCAL_MACHINENetworkLogon

Disable the Outlook Express Splash Screen
You can make OutLook Express load quicker by disabling the splash
1. Open RegEdit
