Great. 
In the old days I would always manually remove the build tools from the %PATH% environment variable.
I don't know how long you've been developing with C++ on Windows but in the old days (90's- 2000's) the build tools were added to the %PATH% environment variable. But it was causing alot of problems because developers would install the Windows SDK which had it's own compiler and linker. Also device driver developers would install the DDK which yet again had it's own compiler and linker. Then there were some guys (like me) that would have VC6,VS2005,VS2008,VS2010,VS2012.NET,VS2013 all installed on the same workstation. I was so happy when VS2015 allowed me to compile with older versions. It meant that I didn't have to install 5 different versions of Visual Studio.

I think I see the problem right there. I wonder why microsoft didn't?

Sane thing (meaning not in the cards for MS): set the env vars to the latest compiler, and allow the user to run a batch file to set the env vars for the older compilers. Better yet, make the latest compiler support older compilation**
** which would have been easier if microsoft hadn't spent years ignoring the C++ standard
Insane thing: Make everyone's life harder by not having sane defaults, and by using crap compilers for years before finally deciding that standards matter.

It's been a really long time ago but I believe with VS2005 there was a post-install step "Add build tools to environment" or some such. It caused alot of problems because developers would install VS2005 *after* VS2008/VS2010 and then they would go and compile the boost library or something and BJAM would use the older VS2005 compiler.
Anyway what you are proposing is more viable today now that VS integrates the older build tools.

Yeah, see I wouldn't have made that decision. I would have included "Add build tools to environment" with every version, and made it replace the old PATH variables and such. More work, but way better in the end. I want to say (but it's a guess) that this is what happens when GCC is installed, or something similar, but I could be wrong.

gcc (on Linux) generally installs different versions as symlinks in /usr/bin to architecture/version specific executables. Each symlink has the version appended - this is what my /usr/bin contains:
lrwxrwxrwx 1 root root 22 Dec 4 2019 /usr/bin/gcc-7 -> x86_64-linux-gnu-gcc-7
lrwxrwxrwx 1 root root 22 Mar 10 2020 /usr/bin/gcc-8 -> x86_64-linux-gnu-gcc-8
lrwxrwxrwx 1 root root 22 Apr 23 2020 /usr/bin/gcc-9 -> x86_64-linux-gnu-gcc-9
And then gcc (with no version) is a symlink to one of the versioned symlinks (e.g. gcc -> gcc-8). All this means that using a specific (major) version of gcc is pretty simple...
If you want to compile 32-bit code rather than 64-bit, then install g++-multilib and compile with the -m32 flag.

As far as I'm concerned, VMs are the best thing to have been invented to keep my build systems clean and manageable. Separation of concerns and that type of thing.
My understanding is that containers are intended to take things one step further. Maybe it's because I'm now set in my ways, but nothing I've read so far about containers actually seem to make things simpler still to make me want to change my methodology.
Same with multibooting. Why bother? In this day and age, as far as I'm concerned, rebooting is a sin. If someone has to abandon what they're working on to boot another OS, IMO they're doing it wrong.

Yeah,
The only time I use a VM is when I am doing device driver development. That way when I break the operating system I can just rollback. It's also a necessity for attaching WinDbg and debugging from the host machine.
Regarding the VC6,VS2005,VS2008,VS2010,VS2012.NET,VS2013 setup... I've got a second workstation right next to me with that setup. There are zero problems running all those versions of visual studio as long as you do not have default build tools in your %PATH% environment variable.

Agree, my workstation is too fast, I can run 3 operating systems in a VM concurrently and it doesn't seem to impact anything. The solid-state drives make a huge difference. I don't even need this much speed.

My current VM host is an i7-4820K (Ivy Bridge generation, I believe), overclockable but I never bother with this sort of stuff. While it's getting long in the tooth in terms of age, I currently have 9 VMs running simultaneously as I'm writing this (roughly twice as many powered off), with individual VMs being allocated anywhere between 2 and 16GB of RAM.
With a total of 64GB of RAM, memory limitations is a problem long before CPU performance. Mind you, I've never run (for example) VS natively on the host, so I don't have figures to compare with, but suffice it to say that I've never felt that anything running on any of the VMs was "slow" in the sense that I'd be expecting anything to run much faster if it was running on the raw hardware.
And really, the only reason my VM host was upgraded from a Sandy Bridge CPU is that the board it was sitting on had a limit of 32GB of RAM, and I was constantly running out. That machine got repurposed from a VM host into a gaming rig. My current VM host will probably go through the same path, once I decide my gaming machine is getting too slow. Right now, I fully expect that, when I decide to replace the machine, it'll be because I want to double the RAM rather than anything to do with CPU performance.

Moving in that direction myself. The tools out there you think you want can so fry your machine. I cite two examples:
1) Platform Builder from MS. After installing, wiped my build environment. Never again.
2) Intel Vtune. Ouch again
You just have to protect yourself. Rollbacks don't cut it any longer.

why, and I ask in all professional seriousness, would you want an application using a variety of compilers and linkers and hoping Microsoft got it right?
Sounds like a recipe for a) suicide b) grief c) project failure d) infinite income (I'm a contractor).

Due to how C++ dependencies work... (and Windows SDK incompatibilites/changes) most project maintainers use the same compiler version for patching and bug fixing for older projects. If the software you are maintaining is 10 years old... then it's probably running on older hardware and operating systems.

CALL "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall" x64
in a command script does it for me (or x86 if you want 32 bit).
I can then run the compiler (cl) from the command prompt. I have tried to use VSCode extensions and projects but never managed to get it to work.

Yes I know how to do that.
That is not the problem.
The problem is that that kills workflow. I can no longer click on my project folder and go "Open with VS Code" because Microsoft stinks.
If microsoft didn't stink (like that will ever happen) they would run vcvars from inside VS Code when you're using the C++ extension

You're not the only person to feel that pain...
As it happens, I use MSVC with VS Code for most of my development. Intellisense works fine, and I build from the integrated terminal. This relies on a batch script I wrote years ago that would call the appropriate Visual Studio setup script before either dropping back to the CMD prompt or jumping into a bash shell (used to be msys2 bash, now I use WSL bash). The way I've configured it, VSCode uses the script to set its integrated terminal up for MSVC2017/x86.
Here's the Visual Studio 2015 part of that script's code (my script supports MSVC 2003, 2008, 2010, 2013, 2015, 2017 and 2019 - fortunately, 2013 is the oldest one I use at all now!):
if not exist "C:\Program Files (x86)\Microsoft Visual Studio 14.0\vc\vcvarsall.bat" (
call :not_installed "Visual Studio 2015"
exit /b 1
)
rem %~1 is either x86 or amd64
call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\vc\vcvarsall.bat" %~1
goto :eof
Yes, hard-coded paths suck, but ¯\_(ツ)_/¯

Mostly due to the same as always...
Somewhere in the process a manager comes with totally bizarre requirement and additionally ordering a magenta icon opening the pandora box. Then all technicians have to interrupt what they are doing and a time later when coming back to the developing process with 5 different "what was I doing?" ending a time later in some critical "oops, I forgot XX". Then it continues with "damn it... without XX I can't YY... I will need to workaround it with ZZ" and having to ship the release version with an unfinished chaotic version...
Is not that obvious?

The character I'm having a problem with is the double quote. I tried using [\"] but that didn't seem to work. 
I'm trying to get a certain size and thickness zip bag (7" wide x 5" deep x 4 mil thick), something I was able to get a few years ago, but now that I've run out of the 25 that I had gotten, I'm looking to get more.

Use "feet" or inches or whatever fancy unit " is supposed to stand for.
This is what happens when one does not want to use proper units.

Ah. You aren't a imperial measurements fan than?
Quote: In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to "How much energy does it take to boil a room-temperature gallon of water?" is "Go %^$# yourself" because you can't directly relate any of those quantities.

I once overhead a conversation from someone stating that the metric system is awful, citing as an example that if you wanted a piece of wood 12ft (4yd) x 1 1/2in x 2in (a common size) you would have to ask for 3.6576m x 38.1mm x 50.8mm.

The answer is 'not the same as an imperial gallon'
Did you know that Americans only have approx. 6 pints of blood, whereas Britons have approx. 8 pints of blood? (Due to the difference size of their unit of 'pint')

US pints are smaller than Imperial pints - 473ml vs 568ml respectively - so I'd expect that to be the other way round.
