Windows 10: Creators update Taskbar shrinks after reboot

It is about exactly what you are stating that it is not about. The problem has been around as I stated since Windows 7 SP1. Use the links I gave in post # 12.

 

2 of those 3 pages do not even have the word "size" in them the third has it in the comments with someone asking how to change text size, like I stated my auto hide is working fine. The resizing of my task bar is the issue I am having the only time I see my task bar is if I move the mouse to the bottom of the screen or if I hit the windows key to pull up the start menu.

So since my auto hide is working but I do not have the registry key from a page that is over 2 years old, and another of those is over 6 why should I add it to possibly break something by using old information when there also is comments on those pages that they do not work on the newer versions of windows?

 

Same problem and, yes, it has been a continuing Windows problem for almost ever. Per an earlier comment, I disabled Cortana just to see what would happen. That actually solved the problem. I don't know if I'll leave it disabled or live with the problem, however. Just a shame that Microsoft is so poor at fixing something that has annoyed so many users for so long. It's one of the things that gives Windows an undeserved bad name. If you need to know how to disable Cortana, I found it on PCWorld.com here.

To clarify, when I say "Same Problem.", what I mean is this. I have my taskbar set to autohide and to have two lines of icons. Upon restart, it continues to autohide but always converts to one line of icons. I believe that is what the OP said. Disabling Cortana resolved that problem. Thanks.

 

I have only recently upgraded to windows Creator and suffered from losing the bottom row of the taskbar each time I restart windows. I have tried lots of permutations 'supposed fixes' but my latest (might be different tomorrow!!) observations highlight the taskbar TOOLBARS: - If I remove all Toolbars from the taskbar, Restart = NO rows are lost.- With a toolbar applied to taskbar and taskbar locked Restart = NO rows are lost.- With a toolbar applied to taskbar and taskbar NOT locked Restart = ONE row lost. I also use a 3rd monitor with my laptop via a XCSOURCE USB 3.0 To HDMI HD 1080P Video Cable Adapter Converterwith this there 'seems' to be an extra problem:- With a toolbar applied to taskbar and taskbar locked Restart = ONE row lost.

 

I have the same issue. After the last W10 update (creators?, back in April), my taskbark keeps shrinking on each reboot. It was set at 2, then it shrinks to 1. I took some advice from another website to set it to 3, then it will shrink to 2 and stay at that size -- but it shrunk again on the next reboot back to 1. I reset my theme from custom to default, and the issue still occurs. Any ideas? At one point in time I remember updating my monitor default screen sizes because whenever I used my KVM switch, it would reset the monitor size to 640x480. Anyone who is experiencing this issue have a KVM or has updated the monitor settings?

Not a critical error, but annoying to say the least -- you would think a simple thing like keeping a setting in between boots wouldn't be a big deal, apparently it is... especially when they "pushed" the update on me in the first place!

Any ideas on how to fix? anyone?

 

My similar problem is that I unlock the taskbar, set it a a height of two and lock the taskbar. As long as I am still on the computer the taskbar hides as it is set and it stays at level 2. Then I shut down. When I return and boot up, the taskbar is reset to 1.

The odd part is that it is not consistent on the desktop, but is consistent on the laptop.

 

Problem solved.
Run gpedit.msc to open Group Policy Editor and navigate to
User Configuration > Administrative Templates > Start Menu and Task Bar

Simply enable the 'Lock all Taskbar settings' rule.
