its probably not the best idea to do so. certainly for the files, yes, but when applications are installed they write data to the registry, which is necessary for the proper operation and uninstallation of the application. its best to copy the files to a third partition (for data only) and then so a clean install of w2k on another partition, then reinstall all software under w2k to that w2k partition. the data partition thing is debateable but simply copying files over from one windows installation to another is just silly.
