Is there a way to increase the font size of the Date/Time in the system tray? I have a 4K monitor and the font is teeny-tiny.

I use T-Clock, its free and fully customisable.

Thanks, but I tend to stay away from software that requires a bunch of research just to figure out how to use. That looks horribly complicated.

I appreciate the effort, though.

[edit]

And sadly it doesn't seem to run on my win10 system. The x64 version locks everything up and I had to reboot. and the 32bit version doesn't display anything anywhere.

Is the supposed to run with NextSTART?

Alas.

I'm sure the topic of T-Clock / Tiny Clock has come up before - have a search for it, there may be answers there.

Other than that, the Windows system tray clock is ludicrously tiny even on smaller resolutions and of course NexSTART cannot change that. That's why I've never used it myself. I would use the Winstep clock module if you want a clock in the taskbar.
