If you’re working in IT support – or trying to break into it – there’s a short list of tools that come up again and again. Not because someone put them on a checklist, but because they genuinely run the show inside most companies. Know these, and you’ll be faster, more confident, and much harder to replace.
The core eight
| Tool | Why it matters |
| Active Directory (AD) | User accounts, passwords, permissions. The backbone of almost every org. |
| Microsoft 365 | Email, Teams, OneDrive, licensing — most companies live here. |
| Remote Desktop (RDP) | Fix user issues without leaving your chair. Fast, direct, essential. |
| PowerShell | Automate repetitive tasks. One script can save hours every week. |
| SCCM (Config Manager) | Deploy software and patches across hundreds of machines at once. |
| Microsoft Intune | Manage devices in the cloud. Critical for remote and hybrid teams. |
| Ticketing Tools | ServiceNow, Jira, Freshdesk — how support actually gets tracked. |
| Browser & Diagnostics | Ping, Tracert, nslookup. Quick network checks that save real time. |
Why these specifically?
Most IT environments are built around Microsoft’s ecosystem. Active Directory handles who can access what. Microsoft 365 is where the work actually happens. Intune and SCCM keep the devices in line. That’s a lot of ground — and a lot of job postings — covered by just a few tools.
PowerShell deserves special mention. It looks intimidating at first, but even basic scripting knowledge puts you ahead of most L1 engineers. When you can automate a task that takes someone else 40 minutes, people notice.
And ticketing tools? They’re how support work becomes visible. SLA management, reporting, pattern spotting — this is what separates reactive firefighting from actual IT operations.
The soft stuff matters too
- Good Communication
- Problem Solving
- Patience
- Documentation
- Willingness to Learn
Technical skills get you in the door. These keep you growing. The engineers who write clear documentation, communicate well under pressure, and stay curious — they’re the ones who move up.
Tools are important, but the thinking behind them makes you great. Start with one tool, go deep, then build from there.
Where to start
If you’re new, pick Active Directory and Microsoft 365 first,they’re in virtually every environment. Set up a free Microsoft developer tenant and get your hands dirty. Then move to PowerShell. The learning curve is real but short.
You don’t need to master all eight before applying for jobs. Most L1 roles expect familiarity, not expertise. Show up curious, ask good questions, and you’ll learn the rest on the job.
