Note the Wallpaper - its exact copy Windows NT has |
OpenVMS is an Operating System with many peculiarities. We wrote about the differences between Server OS and Desktop OS, most has no GUI, we use commands to use it, but OpenVMS has GUI. This GUI is hardware supported and Microsoft Windows NT looks like (as that GUI of OpenVMS came before) OpenVMS, it was not named OpenVMS at that time. The reason is not Microsoft’s pathetic inspiration from other OS’s GUI, but because Prof. Dave Cutler, practically whose brainchild was OpenVMS joined Microsoft. OpenVMS is largely known to the hacker community as unhackable OS.
