I've tried setting up Windows on a USB drive, so I can share some insights based on my experience. Here’s a more detailed breakdown:
Installation Process: To create a portable Windows installation, you can use the Windows To Go feature, which was originally part of Windows 10 Enterprise, but is now largely unsupported—though tools like Rufus have made it easier to set up similar functionality. After downloading a Windows ISO file, Rufus enables you to create a bootable drive by selecting the "Windows To Go" option. This creates a portable Windows environment that you can boot from USB.
Hardware Requirements: For a smooth experience, aim for a USB 3.0 or USB-C drive with at least 32GB of storage, although 128GB is preferable for performance and space. Drives with SSD technology provide noticeable improvements in boot and run speeds. Brands like SanDisk and Samsung offer robust options in this specification range.
Potential Issues and Limitations: Booting from a USB can be slower than traditional SSD or HDDs, and you might encounter performance lags if the USB isn't fast enough. Additionally, you may need to manually install drivers when using different hardware setups, as driver compatibility can affect performance. Software restrictions also might arise since not every app is optimized for a portable setup.
Machine Compatibility: While you can indeed use it across various PCs, real-world use can be tricky. I've personally hit some roadblocks with graphics and network drivers on different machines, necessitating manual updates. For better consistency, you might want to try and keep your portable system within similar hardware families (e.g., all Intel-based systems or all AMD).
Ultimately, while this setup provides flexibility, be prepared to troubleshoot as needed. If you're up for some experimentation, it also offers a fascinating look into making a truly portable workstation. If you want detailed instructions or have specific questions, feel free to ask—happy to help further!
