So if you have an Enterprise license (as many LEAs will have) you can't reimage a machine that comes off the boat with a heap of cackware on it?
Can I use my Windows 7 Enterprise Volume Licensing media to reimage an OEM PC licensed for Windows 7 Professional that is not covered by Software Assurance?
No. Only PCs covered with Software Assurance for the Windows operating system are eligible to have Windows 7 Enterprise installed on them. Windows 7 Enterprise is not available outside Volume Licensing programs, and is therefore not eligible for reimaging.
