Keyboard shortcuts not working in Windows

Does anyone know a fix for this? I already have the preferences to send mac shortcuts to Windows machine but it's not working. This has been working for the past 18 months so not sure what has changed ...

Thanks

 

Oddly enough, I'm not sure if it's Parallels or not, but then again, it's possible that Parallels has messed with my Bootcamp install as well because I've noticed for quite a while that I've lost said shortcuts in Bootcamp as well (either that or I've stopped using it so long that I've forgotten that it was never a thing?).

 

I have done some further testing and it appears to be that the shortcuts behave differently if I try to use them when a Mac window is active or when an Office window is active. I have provided 2 examples of shortcuts that no longer work as expected. In each case the starting desktop is my Mac as shown in the file 'Picture 1.pdf'. I have submitted a technical report #431023912

Example 1 - keyboard shortcut: command, tab => expect to cycle through open windows
Scenario 1
click on any window of Mac software eg - Finder
press command, tab
the cursor cycles through all the open software eg - Parallels, Firefox, Finder, Outlook (open in Windows)

Scenario 2
click on any window of Windows software eg - Outlook
press command, tab
shows picture 3
press command tab
reverts to Mac desktop

Example 2 - keyboard shortcut: command, spacebar => expect to open Alfred
Scenario 1
click on any window of Mac software eg - Finder
press command, space bar
opens Alfred input box

Scenario 2
click on any window of Windows software eg - Outlook
press command, space bar
nothing happens

 

Thanks - works perfectly.
