Start Menu. Possibly a self inflicted problem. It is to small.

but if you keep going toward the right screen edge the start menu suddenly snapped to a larger size. Yea :) Very odd and not at all intuitive.

Sounds as though you figured out how to drag the menu larger - did this solve the issue?

Post another screen if you have a larger pinned Start and the tiles still don't arrange the way you expect.

edit: It bugs me too when I try to shrink the menu - you have to do incremental resize too much and nothing happens, too little and nothing happens.

One other thing:
Do you have the device set to it's native resolution and at 100% dpi? Because your Taskbar looks curiously crowded.

Now that Edwin mentioned... I think you don't have place for the second row. Try to disable that switch: "show more tiles", then it should be place for two rows.

Looks like large icons, Cortana search box, and Task View button take up all the room to me ... but only Mooly can answer these things

Ok, I'm not sure which screen to look at

There might be a clue in the screen shots in post# 1

One, like the image in post# 16, shows 1600x900 - the other shows 1440x900. The 160 resolution difference can make exact screen matching difficult.

Post# 16 looks to be the same as the first pic in Post# 1 ... except the Start is different (1511 in post# 1 and 1607 in post# 16)

Post# 15 has an image that I believe is the layout you're trying to adjust.
If I'm correct, please let me know, you won't have to post another shot until you make a change.

The easiest thing to do is to drag the tiles you want in a group to a new group in an empty area of the pinned Start (the empty group bar is highlighted). Click on the empty group name and name it something meaningful
Then drag other tiles into that group

Do that for all tiles - put them in the group you choose and name the group so it's easy to identify. Don't worry about the arrangement yet - just get the tiles grouped.

When you have your tiles grouped the way it makes sense to you, then drag the group bar to the location you want it on the pinned Start. It might be a little tricky because it auto-arranges. Once you get the hang of it, you can bounce the groups and tiles in or between groups around more easily.

If there is enough room on the pinned Start, you can affect the space between the group columns, if there is not enough space, the tiles wrap.

Sorry, yes I see how that can be confusing.

Post #16 was taken from my Dell 17" laptop and is a current image of how its set up with the Anniversary Update. That is the look I'm after on the old Acer, and pre Anniversary Update I could in fact get close to this (two customisable name fields in the horizontal plane).

Post #1 shows the Dell start menu from just before I clean installed AU. I just took a screen shot of it for reference so that I could rebuild both PC's the same way. Second shot in post #1 is how the Acer ends up when used with the same screen settings (dpi etc) as I've always used.

Did you tried to disable "show more tiles"? In the first picture your tiles settings (row) is narrower.
