Our Top Picks:   

BlueSave Size: 660k Shareware: $99
After you have run the Setup program and rebooted your system, BlueSave will be ready to do its job. When your system crashes, you will see a message on any blue screens that occur indicating that BlueSave has written the screen contents to a file. The file, which you can examine after the system reboots, is located at \WINNT\BLUESCRN.TXT (or your equivalent System Root directory). The saved file is about 8KB in size. Published by Winternals
CPUMon v2.0 Size: 61K Freeware
Use this advanced tool to read the performance counters of Pentium, Pentium Pro and Pentium II processors. Not for the faint of heart, CPUMon is intended for those with a good familiarity of processor architecture. Version 2.0 is integrated with Perfmon.
DebugView/EE v3.24 Size: 100k Freeware
Another first from Systems Internals: This is an Gui/device driver program that intercepts calls made to DbgPrint by device drivers and OutputDebugString made by Win32 programs. It allows for viewing and recording of debug session output, on your local machine or across the Internet, without an active debugger. Version 3.0 has a slew of enhancements, including highlighting, remote monitoring, printing, clipboard support, and more.

DiskMon Size: 41k Freeware
A Windows NT/2000 device driver/GUI combination that together log and display all process activity on a Windows NT/2000 system. You can also minimize Diskmon to your system tray where it acts as a disk light, presenting a green icon when there is disk-read activity and a red icon when there is disk-write activity.

Filemon Size: 64k Freeware
A GUI/device driver combination that monitors and displays all file system activity on a system. It has advanced filtering and search capabilities that make it a powerful tool for exploring the way Windows works, seeing how applications use the files and DLLs, or tracking down problems in system or application configurations. Under Windows NT/2K Filemon can also be used to monitor named pipe activity.

Portmon v3.01 Size: 52K Freeware
Portmon is a GUI/device driver combination that monitors and displays all serial and parallel port activity on a system. It has advanced filtering and search capabilities that make it a powerful tool for exploring the way NT works, seeing how applications use ports, or tracking down problems in system or application configurations.

Regmon Size: 64k Freeware
Regmon is a Registry spying utility that watches and displays information on system-wide registry accesses as they are occurring. This makes it a uniquely powerful tool for learning how Windows works or tracking down problems due to misconfigured Registry settings. Version 4.0 unifies previous NT and Win9x-specific versions of Regmon into a common interface. Enhancements to the device drivers, and the addition of UI features (always-on-top, listview tool-tips) also mark this major version update. Full Source is included.
Other Software Sites:

If you are looking for additional sources of Utilities, try these sites:

Beverly Hills Software
This sites been around a long time, and they do a great job. Software is rated, and easy to find, but some days the site seems a little slow.  
Great site, although a bit tough to navigate. Literally hundreds of programs are available.


SunBelt Software
Sunbelt Software is the world's first and largest provider of 'Best of Breed' NT Utilities. You get mainframe quality tech support, and the best tools all from one source. They also have a few great mailing lists, an online Tech "University", and a tech Glossary.

Well organized, and fast. Gotta love a page that gives a "Five Cow" rating for software. However, you may have to wade through a ton of end user software before you get to applications that you may actually find useful. NT Shareware
One of our favorite sites. All of software is well organized, lists license status, price, size, download time, etc., and the site is searchable.
