Because I just wanted to test TrayStatus I downloaded the 'Download without Installer' version and ran it, which seemed to work fine. However, it has left me with 4 TrayStatus entries in:

PC Settings > Personalisation > Taskbar > Select which icons appear on the taskbar

All of which say:

TrayStatus.exe
TrayStatus Pro Trial 4.4

The first of these entries seems to switch itself back on even after I switch it off. The entries remain even after rebooting the PC.

How do I remove these entries please?

I've tried running the Installer and then immediately uninstalling, but that failed to do the trick.

Many thanks

Nevermind, problem solved. It appears that this is normal Windows behaviour (though that seems very odd to me!), and not the fault of TrayStatus.

How did you solve the problem? I encountered the same issue but not sure this is supposed to be normal Windows behavior.

I noticed the same behaviour and it seems it's quite common for Windows to not remove unused icons from the notification area. I tried various suggested fixes and none worked except Solution #6 on the following website which provides a batch script to remove the old Registry entries. I opened the bat file in a text editor to confirm there was nothing nasty in there. I'm just posting this here as it worked for me. What you do with it is your responsibility:
