About this release
WinToUSB does the unusual job of putting a full, working Windows onto a USB drive so the operating system itself becomes portable. Instead of an installer on a stick, this is the installed system, so you plug the drive into any machine, boot from it, and land on your own Windows with your programs and settings, then take it out and leave no trace on the host. For a technician, a travelling worker or a rescue kit, that portability is genuinely useful.
It builds that portable system from an ISO, a disc or a set of Windows files, and it handles the boot configuration so the drive starts on both legacy and UEFI machines. The same tool also does the more ordinary jobs, creating standard Windows installation media on a stick, and cloning an existing Windows installation onto a USB drive so a working system becomes portable without rebuilding it from scratch.
A fast USB drive is the one real requirement, since a portable Windows lives or dies on the speed of the media it runs from, and a good solid state stick makes it genuinely usable rather than a novelty. This build installs in an activated state so the full feature set, including the portable system creation and the cloning, is available from the first run.

Installation notes
Follow these in order. Most reports of a failed install come from skipping a step rather than from the package itself.
- Extract the archive to any folder you like.
- Run the installer, or unzip the portable build and run it in place.
- Apply the included activation step on first launch.
- Pick the source, an ISO or an existing installation to clone.
- Choose the target USB drive, which will be erased.
- Let it write, then boot a machine from the drive to test.
System requirements
| Operating system | Windows 7 or newer, 32-bit or 64-bit |
| Processor | Any 1 GHz or faster processor |
| Memory | 2 GB minimum |
| Graphics | No requirement |
| Storage | 100 MB for the tool, a fast USB drive for the target |
| USB drive | 32 GB or larger, a solid state stick strongly recommended |
Things worth knowing
- Writing to a USB drive erases it, move anything off the target first.
- A slow flash stick makes a portable Windows painful, use a fast solid state drive.
- Match the boot mode to the machines you will run it on, some want UEFI and some legacy.

What people are saying
Carry my whole Windows on a stick now. Boot it on a client machine, do the work, pull it out, nothing left behind.
Built a portable system on a fast SSD stick. Runs well enough to actually use, not just a novelty.
Cloned my existing install straight onto a drive rather than rebuilding. Booted first try after matching the boot mode.
