One portable app for repair bench work

Start with the work in front of you: migrate profiles, test hardware, deploy apps, inspect networks, recover email data, build media, and document the job.

Profile backup and restore

Move Windows user profiles with guided backup and restore wizards, smart filtering, AES-256 encryption, NTFS permission handling, screenshot settings, and BitLocker key capture.

Diagnostics and benchmarking

Check SMART disk health, collect system details, run CPU, disk, and memory tests, stress-test hardware, monitor thermals, and export HTML, JSON, or CSV reports.

Application migration and cleanup

Scan installed apps, match Chocolatey packages, bulk-install software on new PCs, build offline bundles, download direct installers, and remove applications with leftover scanning.

Vulnerability checks

Review installed software against current vulnerability sources including CISA KEV, NVD, GitHub Advisories, and OSV, then keep technician findings tied to the app management workflow.

USB image flashing

Flash ISO and IMG files, build Windows install media from UUP payloads, and download Linux ISOs from the built-in distro catalog for field deployment jobs.

File cleanup and search

Organize files by extension, find duplicates with parallel hashing, and search content with regex, EXIF, metadata, archive, binary, and hex modes.

Network diagnostics

Run ping, traceroute, MTR, DNS, port scan, bandwidth, adapter inspection, WiFi analysis, WiFi QR management, firewall, route, and network reset tools from one panel.

Email archive tools

Browse PST, OST, and MBOX archives without Outlook, search mailbox contents, preview messages, browse attachments, export EML, CSV, VCF, and ICS data, and convert OST or PST files.

AI-assisted technician workflows

Use a Codex-style assistant for technician chat, evidence collection, approved local actions, workflow orchestration, reports, artifacts, and session context under explicit controls.

Security and elevation controls

Run as a standard user by default, elevate per task through UAC, store AI credentials with Windows DPAPI, and keep transcripts, screenshots, downloads, reports, and artifacts under portable app data.

Field-ready workflows

Built for migration, maintenance, recovery, imaging, and deployment

S.A.K. Utility targets Windows 10 1809 or newer and Windows 11 on x64 hardware. It runs as a standard user, then prompts for UAC only when a task needs elevation.

New PC setup

Back up profiles, collect BitLocker keys, export app lists, install common software, and restore user data.

Repair triage

Check disk health, inspect events, run benchmarks, test memory, review startup load, and build a handoff report.

Offline jobs

Carry the portable ZIP on USB, build offline app bundles, flash boot media, and use local tools without installing a suite.

Data and email recovery

Search messy folders, remove duplicates, inspect mail archives, export mailbox data, and collect evidence for customer notes.
