Medicat USB 21.12 (Mini Windows 10 x64)




MediCat USB is a bootable troubleshooting environment that ships with Windows PE boot environment, and troubleshooting tools. The author of MediCat DVD designed the bootable toolkit as an unofficial successor to the popular Hiren’s Boot CD boot environment. Hiren’s Boot Cd has last been updated in 2012, and while it works in many cases, at least some of the software it ships with is outdated and requires updating.

You get to access all sorts of programs right there, and even more if you are using a version of the toolkit that came with PortableApps included (this one). This include many tools that help you troubleshoot issues on a PC; to name a few: EaseUS Partition Master, HDDExpert, NTFS Permissions Tool, backup tools, Dead Pixel tester, CPU-Z, RegAlyzer, Dr.Web CureIt, Kaspersky TDSSKiller, Malwarebytes Anti-Malware, and Autoruns.

MediCat USB is a complete Hiren’s Boot Disk replacement for modern computers. MediCat USB aims to replace the discontinued and dated Hiren’s Boot Disk. It is geared towards modern hardware, and follows the Ubuntu release cycle with a newly-updated release every 6 months. The author of MediCat DVD designed the bootable toolkit as an unofficial successor to the popular Hiren’s Boot CD boot environment. The menu lists the following options in this regard:

  • 64-Bit windows Recovery: Choice of Microsoft or Easy Recovery options for Windows 10, Windows 8.1 and Windows 7.
  • Hard Disk Tools: includes currently Acronis TrueImage 2017, GParted, Norton Ghost 11.5, Paragon Hard Disk Manager, PloP Boot Manager, SpinRite, SuperGrubDisk, Darik’s Boot and Nuke.

Menu Changes
# I have completely pain-stakingly rewritten ventoy.json, so that anyone can drop in a new updated .IMG, .ISO, .VHD, or .EFI file and rename it in the folder. This means you no longer have to edit ventoy.json when updating your bootable files.
# As a result of the re-write above, the folder structure has also changed to not only take advantage of the new menu, but also in aiding users with tooltips under the menu, giving descriptions of the tools, and telling users wether the tool supports BIOS, UEFI, or both.
# Backup_and_Restore has been renamed to Backup_and_Recovery.
# Boot_an_Operating_System has been renamed Live_Operating_Systems.
# A few icons have been adjusted, and a new icon for UEFI files has been made.
# Version info has been updated.
# New Wallpaper
# Added a holiday hat to the mascot.

Other Misc. Changes
% The Driverpacks in USB:\PortableApps\SnappyDriverInstaller\Drivers\ have been repacked with the latest 64-bit Windows 10 drivers (and all others removed.)
% The latest storage drivers have been integrated into Mini Windows 10’s .wim file.
% A new desktop icon is on the Mini Windows 10 desktop, taking the user to the new MediCat website. (

* The Malwarebytes Bootable WinPE now boots up Malwarebytes v2.2.1.1043, and completes virus scans without crashing. (Please see the _READ_ME!_.txt file at USB:\Programs\MalwarebytesPortable\ for more information.) Thanks @Gremlin220366#4797 for the new Malwarebytes Portable build!
* Fixed the Wallpaper setter so it sets the wallpaper properly in Mini Windows 10. It sometimes wouldn’t set in VMware testing, and has been fixed within pecmd.ini.
* Also fixed Rainmeter not launching in certain instances.
* Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience.



Requirements: USB stick with minimum 32 GiB.

Note: First thing to do is disable any “real-time scanning” in your antivirus software, including Windows Defender. Otherwise you will have applications get deleted from your USB stick during creation, and things won’t work properly.


Note: added a fix for the Archive Extraction issue.
