1.4Software, licences & drivers
Two things quietly keep a workstation healthy: drivers and licences. A driver is the small piece of software that lets a specific device — a graphics card, a printer, a network adapter — talk to the operating system. When a driver is missing, wrong or outdated, the device misbehaves: no sound, no network, a printer that will not print. Keeping drivers current (from the OS or the manufacturer) fixes and prevents a surprising number of problems.
A software licence is the legal agreement that grants the right to use a program, under conditions (number of devices or users, duration, commercial use). Using software without a valid licence is illegal and risky, so part of the IT job is licence management: knowing what you own, how many seats are used, and when renewals fall due. Licences come in many shapes — perpetual, subscription, per-user, per-device, and free or open-source with their own terms — and the details vary by product and, sometimes, by country, so read the terms rather than assume. Drivers keep the hardware working; licences keep you legal. Neglecting either eventually causes an incident, technical or legal.
Section vocabulary
- Driver
- Software that lets a specific device work with the operating system.
- Software licence
- The agreement granting the right to use a program under stated conditions.
- Perpetual vs subscription
- A perpetual licence is bought once; a subscription is paid periodically and stops when you stop paying.
- Per-user / per-device
- Licensing counted by named users or by installed devices — a common source of compliance mistakes.
- Open-source licence
- A licence for freely available source code, still with terms you must respect.
Why does software licence management matter?
In practice — Keep drivers and licences in order
- On a machine, check the device manager (or equivalent) for any device with a warning, and update its driver.
- List the paid software installed and note the licence type for each (perpetual, subscription, per-user...).
- Identify one licence with a renewal or seat limit to watch.
- Record the findings so the information is not trapped in one person's head.
Key takeaways
- A driver lets a device talk to the OS; a missing or bad driver breaks that device.
- A licence grants the legal right to use software under conditions — using software without one is illegal and risky.
- Licence management means knowing what you own, how many seats are used, and when to renew.
- Terms vary by product and sometimes by country — read them rather than assume.
Frequently asked questions
Where should I get drivers — Windows Update or the manufacturer?
Both have their place. Windows Update delivers well-tested, signed drivers for most common hardware automatically, which is safe and convenient. For specialized components — graphics cards, some printers, laptop-specific chipsets — the manufacturer's own driver is often newer and more complete, fixing bugs or unlocking features Windows Update does not carry. The rule of thumb: let Windows Update handle the routine, and go to the manufacturer's official site for a specific device that misbehaves or needs its latest driver. Avoid third-party « driver updater » tools, which are frequently unreliable or unwanted software.
Does software licensing really matter for a small organization?
Yes, on two fronts. Legally, running unlicensed software exposes the organization to penalties and reputational risk during an audit, and the rules can differ by jurisdiction. Practically, poor licence tracking wastes money — paying for seats no one uses, or scrambling when a critical subscription lapses and locks people out. Keeping a simple, current inventory of what is installed, how many seats are used, and when renewals fall due is inexpensive and prevents both a legal problem and an operational one. It is exactly the kind of unglamorous discipline that separates a well-run IT setup from a fragile one.
