Carrying an entire operating system on a flash drive can be very useful, especially if you don't have a laptop. But don't think this feature is limited to Linux distributions - it's time to try cloning your Windows installation.
Learn about WinToUSB
Hasleo’s WinToUSB is more than just a USB formatting tool. In addition to allowing you to create a bootable USB drive for installing Windows, it can also clone your entire Windows installation to almost any USB storage device. When you boot into one of these cloned installations, instead of installing Windows on a connected PC, you can access your installation as if it were on a separate system. The concept is identical to booting Linux installations directly, except with persistence.
This feature is based on a technology called Windows To Go, which Microsoft originally developed for businesses before discontinuing it. WinToUSB fills that gap and extends Microsoft's original offering by extending support to all versions of Windows.
WinToUSB gives you a lot of options for creating a portable installation. The most common and easy-to-use methods are to use an ISO file to create a new installation or simply clone an existing installation. However, this free tool is limited in features. The Professional and Enterprise versions offer additional features like BitLocker encryption , faster copying speeds, and free technical support, among many others listed on the WinToUSB website.
In terms of features, WinToUSB is very easy to use. The process is a simple 3-step process, which involves choosing what you want to do, selecting the installation source, confirming the USB you want to use, and WinToUSB takes care of the rest. The interface is beginner-friendly and clearly laid out, so you'll know what each option does right away. Hasleo also has an official WinToUSB user guide that explains the basic functions of the program.
How to create your own portable Windows environment
As mentioned earlier, using WinToUSB to create a portable Windows environment is very easy. Start by downloading the free version of WinToUSB from the official website. The installation is relatively simple, you just need to follow the Windows installation instructions.
Next, you’ll need a suitable USB drive. WinToUSB will work with any USB drive with enough storage (depending on the setup you’re cloning). However, we recommend using the fastest external SSD you can for this purpose, with a capacity at least equal to the size of your Windows partition. Windows needs to perform thousands of read/write operations, meaning using a cheap, slow USB drive will make your portable installation painfully slow.
Once ready, plug in the USB, launch WinToUSB and follow these steps:
Before copying your Windows installation, WinToUSB will ask you which partitions on the selected USB drive you want to format. It is best if the USB drive has only one large partition; otherwise, you will have to manage the partitions by merging them before using the drive with WinToUSB.
After selecting the partition, leave the other settings as they are and click OK . This will start the copying process, which may take some time depending on the speed of your USB drive and your overall system configuration.
Running Windows Portable for the first time
Once the drive is ready, use it by booting into your computer's BIOS and selecting the drive in boot priority. You can enter the BIOS on Windows 11 and 10 computers through the Recovery settings in the Windows Settings app or by using a dedicated key assigned to the BIOS when you boot. These keys vary by manufacturer; if you're unsure, do a quick Google search .
Any necessary drivers will be installed automatically, although you can pre-install these with Windows by selecting the correct driver folder before copying the setup. This is not recommended, as handling drivers manually can be confusing unless you know what you are doing.
Finally, you should enable BitLocker encryption on your drive. If you leave it somewhere, anyone can boot into your Windows environment and gain access to your files, online accounts, and any other data stored on the drive. However, BitLocker isn’t supported on the free version of WinToUSB, so you’ll need to purchase a Professional or Enterprise license for $29.95 or $299.95, respectively.
Copying your Windows installation to an SSD means you can now carry just one drive with you wherever you go. Whether you forget your laptop or it runs out of battery, just plug in your SSD and install Windows on any computer in no time.
