Apparently, this is a glitch shared on Windows 10's most recent build as of Fall 2017 - Fall Creator's Update. Build 1703 had its problems, such as having to punch in CTRL-ALT-DEL to log in every time I restarted the damn computer, but 1709 fixed it.
1703, however did not give me any issues at all when the language bar was minimized to the taskbar, and I had a custom "Quick Launch" toolbar for months. 1709 Does, so taking out the language bar and having it on top of the taskbar was my workaround until they fix this glitch. Without the language bar minimized, I can still use it and my QuickLaunch survives reboots, even keeps the icons where I left them in the toolbar without having to add '00' to the filename.
Although they should do what they can to fix these stupid glitches, I can sorta live with this, it reminds me of how a NEC PC-98 running Windows 95 ran its language bar.
Thanks for pointing out that key, too, should it go away because should I accidentally leave the language bar minimized before rebooting I can install the key, kill then restart explorer and it's all good, if you're okay with the unsafe, repeated killing of explorer that often (I can't remember needing to kill explorer for any reason in 1703).
