I have worked out that a company I am working for is using the same product key on all its computers. They are all Windows 7 Enterprise PCs. Is this legal for them to be doing this?
Windows 7 Enterprise is only available through the Volume Licensing (VL) channel. Unlike other editions which are available through OEM or retail channels, a single key can be used for multiple activations.
Generally speaking you can use the same key and it will work, but of course Microsoft won't like you for it. Strictly speaking if they ever decided to audit your product key it could be revoked, but of course I have never heard of any case in which this has occurred. You can get a rough idea from Microsoft forums on where they stand on the issue.
As pointed out in comments I preface this looking at your specific reference to Windows 7 Enterprise which is available only through Volume License Center and can use a single activation key to install multiple systems.
