A high-performance, native C# .NET utility for Windows PC setup, optimization, and troubleshooting.
Hat's Multitool is an open-source, compiled native C# application designed to make setting up new PCs, optimizing current systems, and diagnosing issues as fast and painless as possible. Built directly on .NET WinForms and Win32 APIs, it provides instant startup, smooth dark-themed UI, zero script droppers, and comprehensive sysadmin tools.
The latest release of this repo is always available at: HatsThings.com/go/Hats-Multitool
The multitool is divided into primary categories, each packed with a robust set of functions.
Automate the tedious parts of Windows setup with built-in modules:
- Time Zone: Automatically set or correct the system's time zone and configure reliable NTP servers with auto-sync.
- Local Accounts: Easily create or modify local user accounts with live account existence detection, set passwords with a peek toggle, and dynamically grant or remove Local Administrators group membership.
- Bloat Cleanup: Remove common OEM and consumer bloatware (e.g., TikTok, Spotify, McAfee, promotional AppX packages), disable telemetry/diagnostic tracking services, and apply search privacy policies.
- Programs: Automate the installation of essential software via a dynamically loaded remote manifest (
SoftwareCatalog.json), automatic WinGet source preparation, and high-speed Microsoft Office 365 Click-to-Run deployment. - System Properties & Setup Options: Rename computers with NetBIOS validation, join domains/EntraID, configure classic Windows 11 context menus, enable hibernation, and optimize power savings.
Access a curated library of essential sysadmin and maintenance utilities directly from the GUI:
- Storage & Hardware: SMART Info & Benchmarking, Windows Disk Cleanup, BitLocker Management, and on-demand tool runners (WizTree, CrystalDiskInfo, DDU, HDDScan).
- Network & Diagnostics: Internet Speed Test (Cloudflare Anycast), Latency & Packet Loss Monitor, TCP Port Checker, and network stack resets.
- System Repair: SFC System File Checker, DISM Image Repair, Check Disk, and Windows Update Component Reset (all running in standalone elevated console windows that pause before closing).
- Viewers & Utilities: Startup & Autoruns Manager, Reliability Monitor, Battery Report Generator, and OEM ACPI MSDM Product Key reader.
Hat's Multitool is a single, portable, self-contained standalone executable with no installation required.
