Among the small set of new recovery tools included with Windows 8 is the ability to refresh an installation without losing user-installed applications and data. While we like the Refresh feature in theory, it didn't work the first two times we tried it, nor did the Reset. When our machine blue-screened, the only way to get it working again was to perform a clean install.
On the plus side, Windows 8 now can now be booted and installed from a variety of media, including flash drive. This will be a welcome change for time-strapped IT staff, as will the Refresh feature, once it's working.
