Glossary
A reference table of common terms in the EASYDEPLOY system. This glossary helps you read the documentation quickly and consistently. Technical terms are kept in English with enterprise-grade definitions.
| Term | Definition |
|---|---|
| EASYDEPLOY | Windows deployment toolkit running in the WinPE environment, developed by CoreSystem. |
| WinPE | Windows Preinstallation Environment used to boot before installing the operating system. When you boot from USB, WinPE is loaded and EASYDEPLOY runs automatically. |
| USB boot media | USB containing the WinPE environment + EASYDEPLOY + configuration, used to boot the machine and perform deployment. |
| License / Offline License | Usage license packaged in the *.lic file issued by CoreSystem. Verified locally on the machine without requiring internet. Applies to MSP Advanced; Free requires no license. |
| Service Tier (Tier) | Classification: Free (perpetual, 2 profiles, Cloud catalog) and MSP Advanced (annual, USB-SN batch, unlimited). |
| Free | Perpetual free tier — no license required, 2 profiles (1.Tweaks/2.TweaksApp), Cloud catalog with embedded fallback. Suitable for solo IT consultants and micro-MSPs. |
| MSP Advanced | Annual tier by USB-SN batch — unlimited profiles, Self-catalog, full advanced features. Falls back to Free upon expiry. |
| USB-SN | Physical Serial Number of the USB — the unique identifier of each USB device. |
| Bind USB-SN | Mechanism that binds the license to a specific USB (Advanced only): the license only works on bound USB drives. |
| Clone Protection | Anti-cloning protection: prevents copying the license/USB to another device for unauthorized use (via Bind USB-SN). |
| Re-key | Re-issue of a license when the USB is lost/damaged — contact CoreSystem. |
Portable Apps (Softwares\) |
Rescue applications you supply yourself — not included in the release package. Add them via BootBuilder (at build time) or a manual copy + user-config.json. The default configuration references 4 sample tools: MultiDrive, HWiNFO64, Explorer++, Pale Moon. The main window only reserves 4 quick-launch buttons (footer labels and hotkeys adjust automatically); tool count is unlimited — launch extras via F6 (PowerShell)/F8 (Explorer)/cmd. |
| Profile | Post-install customization set consisting of unattend.xml and post-setup.ps1. Free includes 2 default profiles; Advanced is unlimited. |
| OS Catalog (Catalog) | Catalog of valid Windows versions (build/edition/language) available for deployment. |
| ESD | Windows installation file format (.esd) — the source EASYDEPLOY uses to install the operating system. |
| OSCatalog (esd.coresystem.vn) | CoreSystem’s default catalog platform — Free uses the cloud catalog (with embedded fallback); Advanced can use Self-catalog. |
| Cloud catalog | Catalog fetched from the internet (via catalog.url). When offline, the system uses the embedded catalog. |
| Embedded catalog | OS list packaged inside the application — used when the cloud catalog is unreachable. |
| Express Deploy (F3) | Automated deployment mode via a single F3 key — reads pre-configured settings and runs with one confirmation. Available in both Free and Advanced. |
| Vanilla / Business / Express / ZeroTouch | Four deployment methods orchestrated by EasyDeploy: Vanilla (clean Windows), Business (enterprise profile integrated), Express (F3 — automated per config), ZeroTouch (Advanced — boots and runs automatically). |
| ZeroTouch | Fully automated mode (MSP Advanced only): boot the USB → Express runs without any key press. For controlled environments. |
| BYOC | Bring Your Own Catalog — MSP Advanced self-hosts the catalog & ESD (even within a LAN), controlling the installation source. |
| BYOB | Bring Your Own Backend — MSP Advanced self-hosts the telemetry endpoint. CoreSystem ships a ready-made Reference-Backend blueprint to connect. |
| Reference-Backend | Complementary infrastructure blueprint (Cloudflare Worker + D1 / Node + SQLite, with production-ready documentation) — ships with the Advanced .lic. Operated by the MSP; features unlock via license enforcement inside EasyDeploy. |
| Rescue Tools | Rescue toolkit integrated in WinPE (BitLocker, WiFi, Diskpart, Explorer, etc.) via hotkeys — F1, F2 and F4–F12 (F3 is reserved for Express Deploy). |
| Grace period | Grace extension period after license expiry (14 days for Advanced). |
| OOBE | Out-of-Box Experience — the initial Windows setup screen after installation completes. |
