Hi,
Windows To Go is a new feature that comes with Windows 8. This will let you run Windows 8 straight from a USB rather than an internal hard drive, which lets you move around and use almost any hardware without much effort. There is a bunch of information from Microsoft here: http://technet.microsoft.com/en-us/library/hh831833.aspx if you care to read further.
Why use Windows To Go instead of just doing a few tricks and installing Windows 8 on a USB?
The first caveat for Windows To Go is that as of the time of writing this post, there are only two USB sticks supported (You can’t just use any USB stick!);
So, after some chasing around I finally managed to get my hands on a Kingston.
The USB stick is actually quite heavy and thick. About double the weight thickness of a regular USB 2.0 stick, and runs quite hot (not too hot to touch, but enough to actually make you think ‘that’s warm’ when removing it).
To create your Windows To Go USB, you first need to have a Windows 8 installation. From that, search for ‘Windows To Go’ and you’ll find the option to create one.
Aidan Finn’s blog has great instructions on how to do this, so I won’t duplicate his work:
You need to have the original Windows 8 install files too as it looks for the install.wim.
I suggest choosing the option for Bitlocker. If you don’t, your data on the USB will be readable quite easily. The bitlocker password isn’t linked to your login password, or anything else to do with the actual image. You can integrate Bitlocker recovery with AD, but that’s a whole different discussion. For people using a Live ID, you can set up the key so that if you forget the Bitlocker passwords, you can go to
http://windows.microsoft.com/recoverykey and log in with your Live ID, and reset the password.
Bitlocker will also prevent someone cloning the USB key. It’s still a PC, so if one was lost you’d just remove the computer object from AD so it couldn’t authenticate against the domain anymore.
Other things to note about Windows To Go:
The USB stick is 3.0 but will actually work in a 2.0 port. It still works quite fast, I personally haven’t noticed any issue in running it this way.
Windows will try to use inbuilt drivers where it can, but if it doesn’t you’ll need to add the extra drivers onto the USB stick. The driver support is great though, so hopefully this won’t be too much of an issue.
Performance even via a USB 2.0 port was great from my experience, and I’ll use it as my main Windows 8 PC (easy way of doing an inplace upgrade with failback option!). Also, this is a great way to test Windows 8 on different hardware.
If you have any questions or want me to do any tests, please let me know!
