Pick the version, install it cleanly, measure before you tweak, and keep a way back. Every guide names the build it applies to.

Choose the job

What are you doing today?

Start with the task, not the chapter. The type label tells you whether this is a decision, a checklist, a setup or a measured tweak.

Concept

Choose the build

26H2, 25H2, LTSC 2024 or Arm64: support window, hardware and the trade-off.

→Task

Clean install 26H2

Official media, UEFI, TPM 2.0, partitions and the post-install checks.

→Checklist

Set up a new PC

Updates, drivers, browser, privacy and backup before the toolchain.

→Setup

WSL2 on a Dev Drive

Ubuntu on D: with the ReFS limits stated up front, not hidden.

→Method

Measure a game

Frame time and 1% low before any tweak; one change at a time.

→Measured tweak

Memory integrity / VBS

HVCI on/off, three runs each; the CPU delta was inside the noise.

→Troubleshoot

Fix DLL & 0xc000007b

Find the runtime, check bitness, repair the store — never download a random DLL.

→Platform

Windows on Arm

Arm64 native vs Prism, the 26H1/26H2 split and driver blockers.

If you are new

Version → install → first boot

Do not start with a tweak. Three pages get a supported PC, then you can choose a task above.

1. 01

   Choose

   Match the edition and support window to the hardware.

   Compare versions →
2. 02

   Install

   Official media, UEFI, TPM 2.0 and a partition layout you can explain.

   Clean install →
3. 03

   Verify

   Read the build, firmware and TPM state in the guest.

   First 10 minutes →
4. 04

   Go deeper

   Develop, measure or troubleshoot with the build-specific guide.

   Back to the task list →

01

Build-specific

26H2 means 26300; every page says which build and edition it covers.

02

Evidence first

E1 is documentation, E2 is a reproduced lab, E3 is physical hardware.

03

Rollback included

A snapshot, restore point or reverse command. No page hides the way back.
