Tested it on W10 in Common folders like "Program Files" and it worked well.

To test this out I used an app which requires elevation. The error below seems like an awkward way to handle this.. This Errors with "The requested operation requires elevation" when executed from a non elevated process.

..and if your hotel runs an internal network?

The User token must exist else you cannot enable it. Also Impersonations work on a thread basis, it may not be possible to use the Main Thread for this! It may be worth your while to supply us with Process Explorer details as Kas has.

Managed records took a long time to fully implement and yes, records with strings where not managed or let's call them pseudo-managed and allowed. That only leaves the Q why fix or enforce this in: 12.2>12.3..

What I found when originally searching: https://stackoverflow.com/a/64526312

Seemed fine on a smaller section of code base but the same code base in the new 64-bit preview was a disaster..

Same, I've had to recompile several design time packages to solve this.

This dates back a while, pretty sure some cross certificate (driver signing) issuer supplied this as part of an example on how to sign.a driver. I only recall because I had to remove it when we stopped cross signing everything.

/ph - Page hash enforcement verifies the signature on each page of the executable file as it loads into memory, this attaches the cross chain certificates

The installer overwrites the Environmental Path because it wants to dump everything into the OS Path with each install. Or at least that is the only thing I had to change fix for the last three updates.

And WaitForMultipleObjectsEx allows you to add alertable flags to handle Paint message or all depending on requirement.

Which what I ended up doing in a base form. Still that single bit boolean is a quick fix if needed.

A boolean value turned out to be better because at times there are things that should be run OnShow v. OnFirstShow..

Well the documentation language is always MAY 'Recreate the Window', so your mileage may vary. Think some API like SetWindowPos and MoveWindow have that, I know I ran into it while switching desktops via API.. Simpler just to add a FirstShown Property.
