Windows 7: Taskbar customization in Windows 7

Taskbar customization in Windows 7


In Windows 7 Ultimate 64-bit whenever i open more than 13 windows within an application,
in this case Mozilla Firefox, the windows become condensed vertically, no longer showing the
pages themselves, only the title of each window. Is it possible to customize it so that it
shows up to 26 windows on two horizontal rows (13 on each row)?

See photoshopped examples below to see what I mean:

I believe there is. Right-click on the taskbar and select Properties. Tell it to Never Combine in the resulting window.

Hi Jonathan_King,

Unfortunately that has no effect on increasing the number of horizontal rows. All it does is expand each window to it's own taskbar tab as opposed to having them all grouped together for each individual application. As soon as 14 Firefox windows are opened the arrangement changes from horizontal to vertical and the little thumbnails for each window are condensed into just the title names.

Is it at all possible? If not, is there any way to modify it myself? I don't have any programming knowledge...

Not sure whether this will help:

Make the Taskbar "Never combine, but HIDE labels"

Removes the wide buttons with text - far neater IMO

Not really, but it's a step in the right direction. I suppose the solution to my problem is to modify the registry? I'd contact the OP there on how to do this but it seems he doesn't frequent this forum

Is there anyone on this forum i could get in touch with that would know how to do this?

Windows 7

The maximum number of thumbnails that are displayed for any given application in the taskbar is directly proportionate to the screen resolution Windows 7 is running at. So in my case i'm running at a maximum resolution of 1680X1050 which currently nets me a maximum of 13 viewable thumbnails per application. If I exceed that amount, like i said, the arrangement is then automatically changed to a scrunched vertical list without the thumbnails present. I've also tested this on my HDTV capable of 1920X1080, and the maximum was 15 thumbnails. My goal is 25+ on two rows @ a resolution of 1680X1050.

After a couple hours of googling around the net i came across a thread that explains how windows does this. I don't know if i'm allowed to post the link, so i'll just quote the OP:

"every time your mouse hovers over a button, explorer makes some calculations based on your resolution, and makes a second value of maximum thumbnails to show (which is 10 on a 1280x1024 resolution). Then it takes the smaller of the two, and if you have more buttons than this value, it shows a list instead.

To change the default value, which is 16, create the following value in your registry:
NumThumbnails as a DWORD in:

And set it to the desired maximum number of thumbnails to show."

I've created that value in the registry, set it to 24, rebooted and still no dice, stuck on 13. Anyone here got any ideas?

You might also need to adjust this setting in firefox to allow more tabs. I believe firefox will only allow 20 as the default. To change this follow these steps:

1. Open up firefox
2. Type in the address bar "about:config"
3. Click "I will be careful, I promise"
4. Type in the filter bar "browser.taskbar.previews.max"
5. Right click on "browser.taskbar.previews.max" and select modify
6. Set it to the max amount of previews you want.
7. Close and restart firefox.

Hmmm I checked that registry edit I don't think its correct, but can someone double check that.

So i tried both my self, it might have to do with there being a minimum resolution to the previews. In other words the more previews you have the smaller they get, and windows wont allow them to get smaller than a certain size. That's just my guess.

Can anyone help me remove some of the separators from the right side of my Windows 7 taskbar. There is too much space in one area and I think eliminating the multiple separators will bring the icons closer together.
