TechDeck

A portable IT technician command center for Windows.

Copy the folder to any Windows PC, double-click one file, and work. Nineteen tools in one window: diagnose network faults, trace a mail problem from MX to blacklist, find what is eating a drive, recover deleted files, strip a program out completely, recover product keys, block a bad Windows update, and hand the customer a printable report — with no installer and no dependencies.

Why this is a download and not a web app TechDeck reads raw disk sectors, the Windows registry, live process tables and running services. A browser deliberately cannot do any of that — it is the entire point of the browser security model. So the tool runs locally on the machine being repaired. Its interface is still a web page; it just happens to be served by TechDeck itself on 127.0.0.1, reachable only from that PC.

Getting started

Unzip anywhere A USB stick, the desktop, a network share — it does not matter. Nothing is installed and nothing is written outside the folder. It extracts to a version-stamped folder (TechDeck-v1.3.0\), so a copy always tells you which build it is and two versions can sit side by side.

Double-click TechDeck.vbs Accept the administrator prompt. No console window ever appears — the only thing you see is TechDeck itself.

Close the window when you are done The background service notices and shuts itself down about 15 seconds later, unless a long job is still running.

One-time step for PCs without Node.js TechDeck needs a JavaScript runtime. If the machine already has Node.js it just works. To make the folder run on a PC with nothing installed, run app\tools\BUNDLE-RUNTIME.bat once on a computer with internet — it embeds a single portable node.exe. After that the folder is genuinely drop-and-run anywhere, offline.

What’s inside

Network Doctor

Tests the whole chain — adapter, router, internet, DNS server, name lookup, HTTPS. The first red link is the diagnosis. Plus Wi-Fi signal, channel congestion, ping, traceroute and one-click repairs.

Port & SMTP2GO Checker

Hard timeouts, so a black-holed port never hangs you. Tells closed (refused) apart from filtered (silently dropped) — the difference between a server problem and a firewall.

Mail & DNS Toolbox

The MXToolbox jobs, run locally: MX, SPF with a real lookup count against the limit of ten, DKIM, DMARC, thirteen blacklists and a live SMTP session that reads the TLS certificate. Nothing is sent to a third-party API.

Disk Explorer

TreeSize-style analysis at roughly 80,000 files per second — 630k files and 1.3 TB in under 8 seconds. Zoomable treemap, duplicate finder, stale files. Right-click a big folder and it knows whether that folder is an installed program or Xbox game, and offers to uninstall it.

File Recovery

Three layers: every user’s Recycle Bin, a raw NTFS undelete that reads the Master File Table directly, and free-space carving with text search that recovers data whose file record is long gone.

Uninstaller

Removal in three phases: analyse every component (folder, registry, services, tasks, shortcuts), run the vendor uninstaller correctly, then sweep the leftovers. Dedicated Office and Adobe removal included.

PowerShell Workbench

Detects Windows PowerShell 5.1 and PowerShell 7, shows what modules are installed, and offers a curated catalog — SharePoint/PnP, Graph, Exchange, Teams, Az, RSAT — with one-click install and a console to use them.

Licenses & Keys

The Belarc Advisor job — recover the keys already on a machine before you rebuild it. Windows OEM firmware key, decoded installed key, Office and third-party. Flags a “key” that is really just the public generic one.

Windows Update

Remove an update that broke something — and block it, because Windows reinstalls an uninstalled update on the next scan. Blocked updates get their own list you can review and undo.

Tune-Up

Measures junk before deleting it, manages startup programs and services, and runs SFC / DISM / CHKDSK with a real progress bar instead of a wall of scrolling text.

Common Fixes

19 reversible toggles for the everyday complaints — the Windows 11 right-click menu, file extensions, web search in Start, Fast Startup. Every one shows its current state and undoes cleanly.

Image Tools

Drag-and-drop HEIC to JPEG — the “iPhone photos won’t open” job. Keeps EXIF and timestamps, so a converted library still sorts correctly.

Health, Security & Reports

SMART disk health, battery wear, antivirus and firewall posture, crash timeline, bloatware — then one click for a printable report you can hand the customer. Every health score is clickable: it shows exactly which points were lost and what earns them back. Update history comes from the Windows Update agent rather than Get‑HotFix, which on a current machine reported 7 installs out of 955.

Requirements

Windows 10 or Windows 11. Deep undelete and carving need NTFS.

Administrator rights. Diagnostics work without them; repairs and raw disk access do not.

No internet needed once the runtime is bundled. Nothing phones home.

Listens on 127.0.0.1 only and refuses any non-local connection.

Handle with the same care as any admin tool TechDeck can delete files, change the registry, alter services and remove Windows updates. Deletions go to the Recycle Bin, every tweak has an undo, and nothing destructive happens without a confirmation that names exactly what will change — but it is still a tool that edits a live system. Recovery writes are always refused onto the drive being recovered.
