Stop searching forums. Fix it now, and learn why it broke.
When something breaks, people are waiting. You need the right command right now, and you need to understand why it works so the same problem does not come back next week.
TechCheat: The Complete Field Guide gives you both. It takes the quick answers from the TechCheat app and adds the full story behind every fix, in plain English, with real stories from the field.
Inside you will find:
- Windows, Linux and macOS from keyboard shortcuts to administration to deep troubleshooting
- Problem Solver paths that walk you step by step through slow PCs, blue screens, full disks, failed services, boot failures and no internet
- Networking made clear: IP addresses, DNS, ports, certificates, VPNs and Wi-Fi, tested the same way on all three systems
- Security and backups: MFA, encryption, firewalls, hardening checklists, phishing defense, and backups you have actually restored
- The apps you use every day: Excel, Word, Outlook, browsers, VS Code, Git, Docker, AWS, Azure, Google Cloud and Kubernetes
- Enterprise messaging: a rare, practical chapter on IBM MQ and App Connect Enterprise, with reason codes and monitoring tips
- Automation: PowerShell and Bash scripting you can put to work right away
- Practice built in: hands-on labs, review questions, a 30-day practice plan, a 50-question practice exam, and a side-by-side command reference
Every chapter opens with a real situation from the field, gives you the commands to fix it now, then explains what is really happening so you can solve the next problem on your own.
Who this book is for: help desk and IT support staff, students preparing for certifications such as CompTIA A+, Network+ and Linux exams, system administrators, developers, small business owners, and anyone who has become the family IT department.
Machines can run the commands. Only people can take responsibility for what those commands do. This book helps you be that person.
