Ctrl-Alt-Del Inventor To Retire From IBM 459

Posted by simoniker from the resetting-into-his-dotage dept.
wherley writes "AP reports that IBM'er David Bradley, who came up with the (in)famous Ctrl-Alt-Delete key combination, is retiring. The article mentions: 'At a 20-year celebration for the IBM PC, Bradley was on a panel with Microsoft founder Bill Gates and other tech icons. The discussion turned to the keys. 'I may have invented it, but Bill made it famous,' Bradley said. Gates didn't laugh. The key combination also is used when software, such as Microsoft's Windows operating system, fails'." We featured a story on Bradley a few months back.

So that when it's really stuck like that, and ctrl-alt-del doesn't work, you gotta pull the plug. I'd get really mad, it almost became personal, as if the computer was saying "You can't restart until I'm good and ready." Thank goodness for the reset button, for saving the effort of reaching behind the computer.

    • Didn't Bill Gates purposely make the logon for Win NT use ctrl-alt-del as a sort of joke, as a way of saying to the computer world, "i know this is used all the time to reboot, but now windows is so good, it will handle ctrl-alt-del the way i want it to", or something to that effect? I heard this from someone but not sure if it's true or not.
      • I think it's because ctrl-alt-del creates an interrupt request. It goes straight to the OS and can't be intercepted by random software.

          it can't be handled by any input APIs (Win32/DirectInput)... it gets handled directly by the keyboard driver.

          This kind of keystroke is called SAK (Secure Attention Key), as it's not specific to Windows NT.
          SAK is an keystroke (or other event, for example sending "break" on a Sun serial port) that the OS guarantees only the Operating System can ever handle.

            Close, but not exactly correct. It gets handled by "msgina".dll, which is loaded before logon, before anything else. msgina hooks the keyboard IO, and then traps any ctrl+alt+del presses before they reach other running programs. Modified versions of msgina.dll can be used to allow other programs to receive ctrl+alt+del presses.

            This page [216.239.53.104] gives a brief explanation of how things like Novell catch ctrl+alt+del, by replacing msgina.dll.

    I remember Dave Cutler (the man in charge of WindowsNT, also the main VMS developer for DEC), when asked on why did MS use the CTRL-ALT-DEL keyboard combination to log on an NT machine, he said something like: "this combination is sure to be never used by any application". This was taking advantage of the tradition of using it to reboot the computer as everything in the DOS era was running in real mode, so nobody would use it for an application and the NT architecture enabled for the system to intercept it and use it in a supposedly better way. It was thought to be a neat idea.

    Still, I think it was not really clever to teach the end-users such an important keyboard combination. I also remember some users back then thinking it would work the same in 95 as in NT, since both systems' GUI looked so similar.

    The first x86 computer I owned -- an 8086 lugable -- had a keyboard that linked directly to the CPU and no virtualization hardware. Pressing CTRL-ALT-DEL was handy on that system, and over time moving on to 286s, and 386s it still had a function till both the hardware and the operating systems started to trap it. At that point, CTRL-ALT-DEL stopped being a reliable override and started to become a function of software.

    When Windows NT came out, touting that it supported MIPS and Alpha processors, the system boards for those chips did not have even a hint of this original hardware design. I thought that it was reasonable to drop support for that keyboard combination entirely on the software side, and special case trap it for any of the remaining hardware under x86. Drop it as a historic oddity and move on.

    Instead, it was retained as a "security" feature in the NT line for logging in to a machine and locking the machine as if there were something special about pressing CTRL-ALT-DEL on all hardware -- if the keyboard even had those keys or they mapped to anything resembling the hardware on Windows NT came out, touting that it supported MIPS and Alpha processors, the system boards for those chips did not have even a hint of this original hardware design. I thought that it was reasonable to drop support for that entirely on the software side, and special case trap it for any of the remaining hardware under x86.an x86!

    This alone was a big red flag to me that Microsoft didn't get it. Add to it the heavy x86 virtualization used on the other hardware and it was clear MS wasn't entirely serious about portability let alone real security.

    With that, can anyone give a good reason to keep CTRL-ALT-DEL around for any function except as an old-time legacy habit for DOS/Windows users? Is there a technical reason why that combo is more valuable? I can't think of one...

    Down at the bottom of TFA is a quote from Bradley about what exactly led to the PC hardware revolution, i.e. cheap, interoperable, expandable hardware. First was IBM's decision to outsource development of the OS (Microsoft) and CPU (Intel) [giving them expertise which they later used to markey directly to clone vendors].
    Bradley: "Second, we made it an open system. We published a user manual that made it easy for other people to develop software."

    The parallels with the prospects for a PC software revolution are obvious.

    Another quote (by Grove): "It's hard 20 years later to realize how drastic a departure this was from the computer industry's standard practices. Computer companies at that time tended to base everything on differentiation. My software will run only on my platform. The thinking was, 'If I don't differentiate, I'm just in a commodity business.' ... if IBM senior management had fully understood what it was unleashing in 1981, I don't think it would have done this.""

    I think Microsoft realizes exactly what happened with IBM... they lost control of the PC hardware business, but the open platform they originated blossomed in a hundred creative directions. MS has no intention of losing control of the PC OS business.
