Microsoft is constantly changing the command line, which is why books such as Windows Command-Line Administration Instant Reference get outdated. Every new version of Windows comes with new command line utilities. In most cases, these new utilities support new Windows features or allow some new level of maintenance or administration. The RecImg utility creates an image of the Windows 8 installation, including installed applications, to the location you specify. The purpose of this image is to allow a refresh of the Windows installation should something happen to it. A refresh installs a new copy of Windows, but preserves the data and application setup. In many respects, this feature sounds like a simplified version of products such as Norton Ghost. You can read about this new refresh functionality in the Refresh and reset your PC post on the Building Windows 8 site.
I find this new feature exciting because it provides the means for someone like me to recover a hard drive even if I have to support several configurations for a book. It should be possible to create as many images as needed and know that Windows will support them because the feature is built into the operating system. The basic command line for working with this utility is:
RecImg -CreateImage Location
where Location is the directory you want to use for the Windows image. As with any Windows 8 feature, the current version of the utility has problems that you can read about on the Computer Performance site. I’m assuming at this point that the utility will include additional command line switches. Otherwise, Microsoft wouldn’t have included a specific -CreateImage command line switch. Of course, the presence of this new utility means that administrators can perform image updates from a batch file or as part of automated maintenance.
I’ll keep you posted on this, and other, Windows 8 utilities as I have time to review and study them. In the meantime, let me know if you hear anything about interesting new Windows 8 utilities and utility changes. Also let me know if you hear about any utilities that Microsoft decides not to support. Often, you find out about these changes only after you’ve tried to use it in a batch file.
