Windows, explained without the jargon
A plain-English reference to Microsoft Windows — which version you're on, what it needs, how updates behave, and the settings most people look for. Written independently by the team at postfable.co.

Most people meet Windows in the middle of a task: an update notice appears, a setting can't be found, a new laptop needs setting up. This guide covers the questions that send people to search in the first place — in the order they usually come up.
Which version am I running?
Windows ships in generations. The current mainstream release is Windows 11; a large number of machines still run Windows 10, which reached the end of its support period in October 2025 — meaning it no longer receives ordinary security updates. To check what you have: Settings → System → About, where the edition and version are listed under "Windows specifications".
Knowing the version matters, because the next question — "can I install this feature?" — is almost always answered by it.
What Windows 11 requires
Windows 11 has stricter hardware requirements than its predecessor. The headline items are a compatible 64-bit processor, 4 GB of RAM, 64 GB of storage, UEFI secure boot capable firmware, and TPM version 2.0. That last one is the usual reason an otherwise capable machine is told it doesn't qualify.
There is a difference between a supported upgrade and a forced one: installing an unsupported configuration is possible, but it comes without a guarantee of updates and can leave a machine in a fragile state. For a work computer, staying on supported hardware is the calmer choice.
How updates actually work
Windows updates come in a few shapes:
- Security updates — monthly, non-negotiable; these fix holes that are actively being used.
- Cumulative updates — bundles that include previous fixes plus new ones.
- Feature updates — the larger annual releases that add or reshape functionality.
- Driver updates — hardware fixes, sometimes delivered through Windows Update as well.
The practical habit: let security updates install automatically, postpone feature updates for a couple of weeks if the machine is in the middle of deadline work, and never install updates downloaded from third-party "update helper" sites — the official channel is built into the system.
The settings people actually look for
Almost every support question lands in one of these places:
| Looking for | Where it lives |
|---|---|
| Uninstall an app | Settings → Apps → Installed apps |
| Start-up programs | Settings → Apps → Startup |
| Display scale and resolution | Settings → System → Display |
| Storage cleanup | Settings → System → Storage |
| Reset or fresh install | Settings → System → Recovery |
| Backup settings and files | Settings → Accounts → Windows backup |
When a reset is the right answer
Windows can reinstall itself: "Reset this PC" offers to keep personal files while replacing the system, or to start clean. It's the sensible move when problems are systemic — months of accumulated cruft, a broken profile, malware that won't let go — and it's dramatically cheaper than diagnosing every symptom in turn.
Before you press anything: copy your files off, note down the licences you can re-download, and know your sign-in credentials. A reset fixes the software; it doesn't forgive an unprepared user.
Habits that keep a Windows machine healthy
- Install security updates the day they arrive.
- Keep one real backup that you have actually restored from once.
- Install software from the publisher or the Microsoft Store, not from sponsored search results.
- Be sceptical of pop-ups claiming your PC is infected — Windows doesn't report problems through browser ads.
- Restart at least weekly; a machine up for a month is a machine held together by luck.
