Windows downloads, sorted by job
Microsoft publishes several Windows pages, and they are not interchangeable. This page sorts them by job: a clean install, an upgrade, a test machine, or a compatibility fallback.
Microsoft does not have one Windows download. It has the Windows 11 page (with three options inside it), the Windows 10 page for hardware that cannot qualify for 11, an Enterprise evaluation for test machines, and a set of helper pages for the media tool, release status and requirements. Picking the wrong one is the most common reason a reinstall does not match the tutorial someone followed.
This page is the map. Each section names the page, what it is for, and where it sends you next. Every link below goes to a source page that explains the destination and links on to Microsoft's own domain.
The three Windows 11 options live on one page
The Windows 11 download page offers the Installation Assistant for in-place upgrades, the Media Creation Tool for a USB stick or ISO, and the direct ISO for virtual machines and offline installs. They are not the same job, and the source page for that URL walks through which to pick.
If you are reinstalling the machine you are on, the Assistant or the Media Creation Tool is the ordinary route. The ISO is for when you need the image file itself — a VM, an offline build, or repeat installs.
- Upgrading the current PC → Installation Assistant.
- One clean install on one machine → Media Creation Tool.
- VM, offline or kept copy → direct ISO plus a writer.
The fallback and the test image
Windows 10 is still published by Microsoft for hardware that cannot meet the Windows 11 requirements, or for software that will not run on 11. Treat it as a compatibility fallback with a known end-of-support date, not a permanent destination — the source page says exactly that.
The Windows 11 Enterprise evaluation is a genuine, licensed 90-day image for labs and virtual machines. It is the legitimate route to a free test install; it is not a way around activation, and the source page explains why this site links there rather than to an activator.
The helpers you should open before downloading
Three reference pages sit next to the downloads. The Media Creation Tool page documents the tool's current prompts. The release-health dashboard lists known issues for your exact build — check it before reinstalling, because a known issue survives a reinstall. The specifications page lists the requirements, so you confirm the machine qualifies before downloading 5.5 GB.
Check, then download
Open the specifications page to confirm the machine qualifies, and release health to confirm the fault is not a known issue, before you spend the download and the reinstall.
The preview, and the wrong turns
The Windows Insider Program is a pre-release channel for testing, not a source of install media for a production machine and not a free licence. It is listed here for completeness, with the caveats.
What is not listed anywhere on this site: mirrors of the ISO, 'no Microsoft account needed' builds, or tools that remove the requirement checks. Those are the redistributed, unverifiable images a clean install is meant to eliminate.
Official sources in this group
Every card below opens a page on this site that explains what the source is for and links to the vendor’s own domain. None of them hosts a file.
Microsoft's Windows 11 download page: which of the three options to use
Installation Assistant, Media Creation Tool or a direct ISO — what each one is for, and why the hostname in the address bar is the whole point.
The Windows 10 download page, and its deadline
Why Windows 10 is still downloadable, why it is a compatibility fallback rather than a destination, and how to decide honestly between the two.
The 90-day Windows Enterprise evaluation, used properly
A genuine, free, time-limited image from Microsoft. What it is for, what it is not, and why it is the honest answer to 'I just need a test machine'.
Microsoft's own installation-media instructions
Why the vendor's support article beats a tutorial screenshot when the prompts change, and what the article actually covers.
The Windows Insider Program: pre-release builds, not a free Windows
What the Insider Program actually is, how the builds arrive through Windows Update, and why it is a test channel rather than a source of install media for a production machine.
Windows release health: check this before you reinstall
Microsoft's own dashboard of known issues and rollout status for every supported Windows release, and why reading it can save you from a reinstall that fixes nothing.
Windows 11 system requirements: check before you download 5.5 GB
The published Windows 11 hardware requirements, what each one means in practice, and the honest alternatives when a machine does not qualify.
