Tools That Solve Real Problems
Windows is a powerful operating system, but it does not ship with every tool you need. IT administrators need ways to inventory hardware across a network. Developers need to test at specific screen resolutions. Sysadmins need to send messages to hundreds of workstations at once. Power users need to automate repetitive tasks at startup or on a schedule.
This collection of 27 utility programs fills those gaps. Built over nearly 30 years of real-world use, these tools are designed to be small, fast, and focused. Most are fully portable—no installer, no registry changes, no background services. Download, run, and get the job done.
