What is MediCat USB v21.12?
MediCat USB v21.12 is a bootable USB toolkit based on the Windows PE (Preinstallation Environment) system. Created by a developer known as Jayro, MediCat is designed to be a comprehensive replacement for outdated tools like Hiren’s BootCD, offering a modern and fully-loaded experience. It includes a custom Windows PE environment and a massive collection of diagnostic, repair, partitioning, data recovery, and security tools.
Unlike many recovery discs, MediCat is updated regularly and built with current hardware and software compatibility in mind. The v21.12 release is one of the most stable and feature-rich versions to date.
Key Features of MediCat USB v21.12
Let’s dive into what makes this version of MediCat so special:
1. Windows PE Integration
MediCat USB includes a fully customized Windows PE x64 environment, offering a familiar Windows-like interface. This gives users access to a modern desktop, file explorer, and full GUI-based applications — no more command-line only tools.
2. Hundreds of Preinstalled Utilities
This version comes packed with tools for nearly every IT scenario:
Partition tools (MiniTool Partition Wizard, AOMEI Partition Assistant)
Data recovery (Recuva, TestDisk, PhotoRec)
Antivirus scanners (Malwarebytes, ClamAV)
Disk cloning (Macrium Reflect, Clonezilla)
Password recovery (Ophcrack, NTPWEdit)
Benchmarking tools
Network diagnostics
And many more...
3. Driver Support
It includes a huge library of modern drivers to ensure compatibility with the latest hardware, including NVMe SSDs, USB 3.0, and Wi-Fi cards. You can run it on both old laptops and modern desktops without worrying about missing drivers.
4. Offline Functionality
All tools in MediCat USB v21.12 are fully offline, meaning you don’t need an internet connection to run virus scans, clone disks, or recover lost files. This is especially useful in emergency situations.
5. Modular ISO System
MediCat uses a modular system. You can build a USB stick that contains only the tools you need, reducing the size and making it run faster. This is a key improvement over older tools that are bloated and slow.
6. Portable Apps Menu
It includes a PortableApps.com platform, which allows you to run lightweight, portable versions of popular software like Notepad++, Firefox, 7-Zip, VLC, and more — directly from your USB stick.

How to Install MediCat USB v21.12
Installing MediCat might seem overwhelming at first, but it’s actually quite straightforward. Here’s a basic guide:
Download MediCat USB ISO files
You can find them on trusted forums, Reddit (r/MediCatUSB), or the official GitHub page.
Use Ventoy or Rufus
MediCat works best with Ventoy. Simply copy the ISO files to your USB drive and boot into them via Ventoy's menu.
Boot into the USB Drive
Plug the USB into your target machine, restart the computer, and boot from the USB device (using F12/F2/ESC depending on your PC brand).
Start Repair or Diagnostics
Once booted, you'll have access to the full suite of tools in a modern desktop environment.
Is MediCat USB Safe to Use?
Yes — if downloaded from an official or trusted source. However, always scan any downloaded ISO file with antivirus software. MediCat does not contain malware, but some of its tools may be flagged as "hacking" or "password recovery" software, which can trigger false positives in some antivirus programs.
Also note: MediCat is intended for educational and troubleshooting purposes only, and not for piracy or illegal activity.
