I’ve just finished writing a story for Tom’s Guide on using a bo0table WinPE UFD, and doing the research for that story led me to a few interesting discoveries. First and foremost, no self-respecting Vista administrator should be without a bootable WinRE UFD–but perhaps, WinRE is more recognizable as the Windows Recovery Environment that you can fire up from the Windows Vista installation media.
It turns out, you can also follow my instructions on building a bootable WinPE UFD, and then use the imagex utility from the Windows Automated Installation Kit to capture the recovery environment Windows Image (.wim) file from your installation media. All you have to do then is swap the boot.wim file that my process creates in your ISO\sources directory with the boot.wim file that you export from your install media, and presto! you’ve got a WinRE console that boots in under two minutes, instead of having to wait three to five minutes for the same functionality to become available from the Vista installation DVDs.
Because I’m always messing with various Vista installs, I have to resort to the recovery environment at least once a week where I work. I’m guessing that busy system admins with any number of Vista machines to care for can beat that frequency with ease. In such cases, a bootable UFD with the WinRE console ready to hand can help save lots of wait time, and enable more “work time” on affected Vista systems.
Another, perhaps more esoteric use, might be on netbook PCs where disk space can be at a premium. I’m learning how to extend the WinPE environment to run other programs, including Windows Explorer (and some claim, even IE) from within the WinPE context. Because most simple Windows GUI apps (think items in the Accessories folder, as good examples of what this means) will already run in WinPE, it’s not hard to conceive that a somewhat extended WinPE environment could be workable for netbook users seeking to slim runtime system size to 0.5GB or smaller (by itself, the WinPE I describe how to build in my previous blog is about 367 MB in size; WinRE is less than 250 MB, but lacks network drivers and access).
As time goes by, I’m sure I’ll figure out some other cool uses for WinPE as well. If you know of any, please share them with me in the meantime!
