What version of Start10 are you using as that is not normal?

That is odd as I just checked 0.57 against a Win 10 RTM and could not reproduce the problem.

We have an updated build that should be going out later today, so I would recommend trying that out when it comes out and seeing if your problem continues.

Same here with 0.99, hiding Edge and Task View.

I uninstalled Start 8 before doing the update and I have now gone and deleted any leftover folders but it's still happening.

No, nothing installed that affects the taskbar.

Install is English US

Cheers

PS: Clicking on the 'Show Hidden Items' in the system tray brings the hidden icons back, it's annoying but not the end of the world.

PPS: It's not anything to do with Start8 as I just installed Start10 on a machine that never had Start8 on it and the same thing is happening.

Yep, 'show task view' and 'show search icons' are both checked.

It's happening on 5 different machines here.

All 64 Bit.

Not using a shared login.

4 of them were upgrades and my Laptop was clean.

Same problem on all of them.

All I have to do to correct it is hit the 'show hidden icons' arrow.

EDIT: It seems to have stopped happening now, not really sure why but I haven't seen it on any of the machines for over 10 minutes.

This is extremely bizarre.

 I'll let you know if it returns and thanks for the prompt replies.

No it was coming and going but as I said in my edit above, it seems to have stopped on all machines and I can't figure out why, very strange.

I'm having the same issue on 4 devices (1 laptop and 3 desktops), all of which I recently upgraded from Windows 7 to Windows 10.  Every now and again, all of the icons (task view, edge, etc.) suddenly disappear from the task bar.  I have to disable the task view icon to get them to return, but I enable it again right afterwards.  A reboot may or may not be successful.  When it happens again, I will try leaving task view disabled to see if that helps.

Edit:  I'm using the latest version.  I just downloaded it yesterday.  I think it's .99.

It went away for a while but it has now returned, there doesn't seem to be any way to replicate it, it just happens.

I tried unchecking Task view and it seemed OK, 30 minutes later and Edge had vanished again.

Definitely seems to be something to do with Start10 as removing it solves the problem.

I know it's early days so it's no big deal, hopefully someone will find a solution.

I haven't had the problem in a few hours.  The only thing I did was turn of the auto-hide feature of the task bar on my machines having the problems.  Now that the task bar is displayed all of the time, I haven't lost the icons.  I don't know if that means anything or if it has been long enough to know anything for sure, but it's worked for me all evening.

I like mine to auto-hide, as well, but I suppose I'll keep it unhidden until the problem is fixed.

Well, it's been enough time now.  It does seem to be related to auto hide.  I've not had one issue on my machines since unchecking it.  Hopefully we'll see a fix for that in an upcoming release as I like my task bar to auto hide.  I can live without it in the meantime, though.

This should be addressed in 1.0 now we know what the trigger was.

Thanks to everyone who reported this.
