[KBM] Shift Right remains logically pressed in this particular scenario

[DanCaprine]

Computer Information

• PowerToys version: v0.20.1
• PowerToy Utility: Keyboard Manager
• Running PowerToys as Admin: no
• Windows build number: 2004 (Build 19041.450)

Steps to Reproduce

NOTE: it only reproduces remapping Shift, it doesn't reproduce remapping Shift (right) or Shift (left)

1. Create a shortcut in Keyboard Manager mapping SHIFT + F1 to F13
2. Create a shortcut in Keyboard Manager mapping SHIFT + F2 to F14
3. Go to https://keycode.info/ in Firefox or Edge. Verify that F1 and F2 work correctly.
4. Press and hold SHIFT Right and F1. Verify the web page is seeing an F13 keycode.
5. While still holding SHIFT Right, release F1 and press F2.
6. Verify the web page is seeing an F14 keycode.
7. Release all buttons.

Result:

• F1 and F2 are still being seen as F13 and F14 without shift being held.
• Windows Key no longer works on desktop, even when PowerToys is exited.
• F1 and F2 are also being seen as F13 and F14 in other apps.
• Unplug and replug in keyboard. Issues still persist, verifying that this is not hardware related.

NOTE: see comment below by @enricogior

Expected Behavior

• F1 should be sending an F1 keycode
• F2 should be sending an F2 keycode
• Windows Key should still function

@arjunbalgovind ideas?

I'm unable to repro the above behavior on 1909. I will have to see if I can repro this on 2004. @DanCaprine if you get stuck in that state, tapping the Shift key should release the Shift key state, and your Win key should function normally. Similarly tapping F1 and F2 should reset those keys. If Shift is held down then pressing Win key does not do anything which is probably what happened in your case. Did you have any application which was running as admin in the foreground? You could get stuck into this broken state if you hold Shift and press F1 but release them when a window running as admin is in the foreground (this could happen if in your case either F13 was actually a hotkey to launch some application as admin or resulted in a UAC prompt). If that is indeed the case, you can avoid the behavior by running PowerToys as admin.

@arjunbalgovind I can still reproduce this when PowerToys is running as admin, and clicking shift doesn't reset. However, this bug only occurs with "shift", which you need to select manually, and not "shift (left)" or "shift (right)", which might be relevant to testing.

I have lost Win key function since about PowerToy ver 20? and currently at v0.20.1 Tried turning Shortcut Guide on and off as well as Keyboard Manager. Keyboard Manager has no shortcuts in it. PowerToys running in admin mode. Attempting to create a new mapping with Win mapped to Win Right or Win Left has not restored the key.

I've updated the repro steps since it only happens remapping Shift, it doesn't reproduce remapping Shift (right) or Shift (left). To reproduce it, you have to use Shift (right) while holding F1 and F2. The bug causes Shift to remain logically pressed and opening Notepad and typing any letter shows that. Pressing both Shift (right) and Shift (left) at the same time, reset the logic state of Shift.

Tested on 0.29.3.
