Miscellaneous Utilities
The utilities in this chapter are not for diagnostic or troubleshooting purposes. They
are simple utilities I wrote for my own needs or amusement and later published to the
Sysinternals Web site.
■ RegJump launches RegEdit and navigates to the registry path you specify.
■ Hex2Dec converts numbers from hexadecimal to decimal and vice versa.
■ RegDelNull searches for and deletes registry keys with embedded null characters in
their names.
■ Bluescreen Screen Saver is a screen saver that realistically simulates a “Blue Screen of
Death.”
■ Ctrl2Cap is a keyboard filter driver that converts Caps Lock keypresses to Control
keypresses for those of us who are used to keyboards where the Control key is located
immediately to the left of the A key.
RegJump
RegJump is a command-line utility that takes a registry path, opens the Windows RegEdit
applet, and navigates RegEdit to the path you specify. You can specify the root key in standard
or abbreviated form, or even in Microsoft Windows PowerShell drive-specifier format.
Note that it is not necessary to quote registry paths that contain spaces. The following
commands are all equivalent:
regjump HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
regjump HKLM\SYSTEM\CurrentControlSet\Control
regjump HKLM:\SYSTEM\CurrentControlSet\Control
RegJump works by programmatically sending keystrokes to RegEdit. This means that on
Windows Vista and newer, RegJump must run with at least as high an integrity level as that
of RegEdit. Also note that if you are a member of the Administrators group, RegEdit requires
elevation, so RegJump must also run elevated. If you are logged on as a standard user,
neither RegJump nor RegEdit require elevation.
