There was also a few dozen bytes of patch space set aside for you to write your own subroutines, in case you needed to add custom support for your printer.

I remember my WordStar manual coming with details about which bytes to patch to do what. (My recollection is that most CP/M programs were configured via patching. If you wanted to configure a program to specify where to put its temporary files, you needed to do some sort of program-specific configuration, like patching a byte in the executable to indicate the drive letter where temporary files should be stored. Since it had no environment variables, there was consequently neither a TMP nor a TEMP environment variable. That sounds like a strange place to start a discussion of environment variables, but it’s actually important. The CP/M operating system had no environment variables. The operating system common on microcomputers was CP/M. Why two? And if they disagree, then who’s right? There is one called TMP and another called TEMP.

Since I don’t want separate sessions (mainly coz I don’t know what they are used for in terms of XenApp) I also went ahead and disabled that from Windows Components/Remote Desktop Services/Remote Desktop Session Host/Connections where you can find a setting called “Restrict Remote Desktop Services users to a single Remote Desktop Services session”.If you snoop around your environment variables, you may notice that there are two variables that propose to specify the location of temporary files. Here I set “Do not use temporary folders per session” to true and now I don’t have multiple TEMP folders. The relevant setting is under: Windows Components/Remote Desktop Services/Remote Desktop Session Host/Temporary folders. The number used for the directory is actually the session ID number for the user session.Īnyhow, what can I do to fix this? Turns out we can disable this multiple TEMP folders per session thing via GPO. It is just a mechanism to keep the temp variable locations unique and separate between users. With the evolution of the OS in the Vista timeframe, Micrsooft added the ability for you to have multiple users logged into the OS console at the same time and switch between user sessions, to do that they used the same concept borrowed from the Windows Terminal Services side of the OS.

Microsoft added it to their OS subsequently as they added Windows Terminal Services to the OS, and this only happened when logging into a terminal services session. This concept was originally was created by Citrix when they produced WinFrame as a way of handling multiple user sessions on the same machine as a way to handle keeping each user’s temp location unique to each user. Server or desktop, I was under the impression you were restricted to a single session but I guess I was mistaken. I had no idea a single user could have multiple sessions open on a machine.

(All the above info was from this helpful TechNet page by the way). I had no idea of these, but sure enough when I checked the registry location TEMP and TMP were set there just like I was seeing. They are stored at HKCU\VolatileEnvironment. These are not saved between log offs or reboots. Volatile variable – a variable that applies to the current context of the currently logged in user.(Hmm, now that I think about it was that for Linux or Windows?) I kind of knew of such variables (though I hadn’t formalized them in my head) coz I knew you could launch a process and put a variable assignment before it to set the variable just for that process and its children. Process variable – a variable that you can apply to a particular process and its children.User variable – a variable that applies to the currently logged in user.

These are stored at HKLM\System\CurrentControlSet\Control\Session Manager\Environment. System variable – a variable that applies to all users of the system.I knew two of these and kind of knew the third of these, but I had no idea of the fourth one. Reason for that is that there are 4 different contexts where a variable is set. But that seems to be ignored as all my users were getting these variables set to %USERPROFILE%\AppData\Local\Temp\ 2 or some similar number. For my XenApp servers I had set the TEMP and TMP environment variables via GPO to be the following: %USERPROFILE%\AppData\Local\Temp.
