Windows Utility Software and IT Tools

29 tools for IT administrators, power users, and anyone who wants more control over Windows

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 without visiting each desk. Developers need to test web layouts at exact screen resolutions. Sysadmins need to push critical messages to hundreds of workstations before a maintenance window. Help desk teams need to check a user's RAM specs, product key, or system uptime without installing diagnostic suites on their machine. Power users need to automate repetitive tasks at startup or on a schedule without writing scripts from scratch.

This collection of 29 utility programs fills those gaps. Every tool was born from a real need in a real work environment. Windows Product Key Viewer exists because retrieving a lost activation key should take seconds, not a phone call to Microsoft. Port Listener exists because testing whether a firewall rule actually works should not require setting up a full web server. Log Info exists because walking to every desk in the building to check hardware specs is not a reasonable way to do an IT audit. These tools were built to save time, reduce frustration, and eliminate unnecessary complexity.

What makes these utilities different from the dozens of similar tools you will find online is their design philosophy: do one thing well, stay out of the way, and leave no mess behind. Most are fully portable - a single executable with no installer, no registry changes, and no background services. Copy one to a USB drive, run it on any Windows machine, and delete it when you are done. No trace left behind. That approach has earned the trust of IT professionals, enterprises, and government agencies worldwide for nearly 30 years.

What You Can Do With These Tools

The 29 utilities in this collection cover a broad range of Windows administration, automation, and productivity tasks. Here is a sample of the kinds of problems they solve:

  • Recover Lost Product Keys - Retrieve your Windows activation key directly from the registry in seconds. Essential before reinstalling Windows, migrating to new hardware, or auditing software licenses across an organization.
  • Test Network Connectivity - Listen on any TCP port and see live connections in real time. Verify that firewall rules, port forwarding, and NAT configurations are working correctly without setting up a full server stack.
  • Inventory Workstation Hardware - Automatically collect RAM, CPU, disk, OS, and network details from every computer on your network at login. Generate reports for IT audits, upgrade planning, or compliance documentation.
  • Push Messages to Users - Deliver mandatory notifications at login, send broadcast messages across the network, or create standalone executable alerts that run on any PC without installation. Track acknowledgments and enforce policy compliance.
  • Automate System Tasks - Control keyboard states (Caps Lock, Num Lock, Scroll Lock) in login scripts, delay program launches at startup, manage autostart entries, and schedule shutdowns or restarts - all from the command line with full scripting support.
  • Search and Transform Files - Find and replace text across thousands of files in seconds, batch resize JPEG images for web or email, and copy directory tree structures for project templates or migration planning.

Built for IT Professionals and Power Users

These utilities are used daily by a wide range of professionals. System administrators deploy them in login scripts to inventory hardware, toggle keyboard states, and push mandatory notices. Help desk technicians carry them on USB drives to diagnose issues on the spot. Developers use them to test network configurations and resize browser windows to precise breakpoints. Even home users benefit from tools like Windows Product Key Viewer when it is time to reinstall or upgrade.

What ties all these use cases together is the need for tools that work immediately, without setup, and without leaving anything behind. When you are standing at a user's desk trying to figure out why their machine will not activate, or testing whether a port is open from a client's network, or pushing a critical security notice to every workstation before the end of the day, you need tools that just work. That is what this collection delivers.

Why Choose RJL Utility Software

The internet is full of Windows utilities, but most come with trade-offs: ad-supported interfaces, bundled software in the installer, telemetry you did not agree to, or executables that have not been updated since Windows 7. RJL utilities take a different approach:

  • Lightweight and Portable - Most utilities are a single executable under 1 MB. No heavy installers, no .NET dependencies, no background services. Copy to a USB drive and run on any Windows machine. Delete when done - nothing left behind.
  • Built for Automation - Many tools include full command-line support with documented switches and return codes. Drop them into login scripts, batch files, scheduled tasks, or Group Policy startup sequences. They are designed to run silently and reliably without user interaction.
  • No Ads, No Tracking, No Bundled Software - Every download is exactly what it says. No hidden toolbars, no telemetry, no cryptocurrency miners, no "recommended" software checked by default. Clean, focused tools that respect your system and your trust.
  • Trusted by IT Professionals Since 1996 - Used by system administrators, help desks, and enterprises worldwide. Nearly 30 years of continuous development, real-world testing, and user feedback have produced tools that are stable, reliable, and battle-tested in production environments.
  • Wide Windows Compatibility - Supports a broad range of Windows versions from legacy systems still running Windows XP to the latest Windows 11 builds. Many organizations run mixed environments, and these tools are built to work across all of them. See each product page for specific OS requirements.
  • Actively Maintained - Unlike abandonware that breaks with every Windows update, these tools receive ongoing maintenance. When Microsoft changes how product keys are stored, how services are managed, or how screensavers are registered, these tools get updated to match.
