1Before you build a provisioning USB - kit, space, time and downloadsEverything to have ready BEFORE your first stick, so nothing surprises you mid-build: a 16 GB+ USB stick (the whole stick is erased; on sticks over 32 GB the boot partition is capped at ~30 GB - that is normal), a Windows 10/11 PC with admin rights and about 30 GB free disk, the Windows ISO downloaded in YOUR machines' language, and honest time expectations: the first build does one-off preparation (roughly 35-90 minutes depending on options), every build after that is about 10-15 minutes, and the target machine's install takes another 20-40 minutes. · 9 steps · ≈ 15 min
4Build a Decolla provisioning USB (Windows + build config + apps)Make ONE bootable stick that installs Windows unattended, applies the build config, and installs the apps offline. You supply the customer's own LICENSED Windows ISO (we never redistribute Windows) and a plain 16 GB+ USB. BEST: download the ISO in your profile's LANGUAGE (Windows 11 ships in 38 languages - e.g. English UK) so the media natively matches: zero prompts, nothing to inject. Fallback: the builder can slipstream the language pack (~143 MB, auto-fetched) into the image - but NOT on 25H2 (26200) media, where offline language injection has a known Microsoft defect. The image can also be serviced offline: latest Windows update baked in, per-model drivers injected, consumer apps stripped (guarded blocklist). Pick the mode in the cockpit: Standalone (fully offline, known admin login) or Autopilot-prep (OOBE stays so the device Entra-joins and Intune-enrols). The build is silent + guarded; boot-test on a spare machine (it wipes the target's disk). · 14 steps · ≈ 20 min
7Upload your own app (MSI/EXE) - install it via Intune, the USB stick, or bothFor apps not in the store - your RMM agent, a VPN client, a line-of-business installer. Point the cockpit at your MSI/EXE: an MSI's name, publisher and silent install are read from the file itself, the binary uploads straight to your organisation's private Decolla storage, and you choose whether it installs via Intune, from the USB stick, or both. Any token stays private to your build. · 10 steps · ≈ 8 min
11Create a Windows Autopilot deployment profile and Enrollment Status PageCreates the deployment profile that shapes a registered device's out-of-box experience, assigns it to your dynamic Autopilot group, and configures the Enrollment Status Page that gates first sign-in until apps and policies land. The trap: the profile only ever reaches a device through that group, and membership can lag hours behind registration, so confirm Profile Status reads Assigned before you touch the machine. Since Aug 2026 the Decolla build zone does the reading and matching for you: an Autopilot-prep build lists your tenant's deployment profiles matched by what they DO (join type, single-user vs shared, standard vs administrator user, pre-provisioning, hash harvesting, the OOBE screens) - never by name - and offers to link the match or, on your press only, create one under a name you choose and verify it by a separate read. This guide remains the manual route and the reference for what each setting means. · 12 steps · ≈ 20 min
