I have already tried adding the registry entry in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced as ExtendedUIHoverTime with a value of 30000 seconds but it doesn't work. It still shows the Microsoft damned thumbnails, any idea?

7+ Taskbar Tweaker can disable taskbar thumbnails. It's very lightweight and supports a lot of other useful customizations.

It's nice, but it only works while the program is running.. It doesn't actually change something in the regedit or Win options. Do you know the entry that it changed it in the registry so it can be done manually?– MikeDec 14, 2018 at 3:11

@Mike The idea of 7+TT is to keep it running and it's built with this in mind. It works by patching Windows components in memory, so it doesn't waste CPU and uses negligible amount of RAM. No reason to worry that it's running in the background. Just install it, configure it, forget about it. Dec 14, 2018 at 8:02

Thanks for the prompt reply.. but what is the actual patching that happens in the memory or temp. registry edit that it's actually done by it? II tried to look using "Regfromapp", but I couldn't find it.– MikeDec 14, 2018 at 9:51

@Mike It doesn't edit anything in the registry. Most of 7+TT's features aren't available as registry tweaks. It patches Windows's code to achieve these effects. Dec 14, 2018 at 13:01

I used this method:
In:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Taskband
In the right-hand pane, right-click and choose New – DWORD (32-bit) Value . Give it the name NumThumbnails
. You’ll create the 32-bit DWORD whether you have 32-bit or 64-bit Windows. By default, it should have a value of 0, which is what we want.
@anadrol's answer is correct and doesn't involve installing any potentially unwanted software. Here's a powershell answer:
New-ItemProperty HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband -Name "NumThumbnails" -Value 0 -PropertyType "DWord"
Then restart explorer:
ps explorer | kill
Thumbnails will be replaced with a window list:

@user33276346 what happens after you run each command? 'Not working' doesn't really help anyone. Jun 18, 2018 at 9:43

1added the value, the command says it is already there, restarted explorer, seen it restart, the preview is still there, laughing at me :) maybe windows had some updates. Nov 15, 2018 at 11:47

It doesn't work for me either. I'm on the "April" version of Windows 10. The Powershell script executed correctly and the entry is present in the Registry editor. Explorer restarted correctly. I've also restarted the computer, with Hibernate off. But the evil previews (tiny screenshots) are still glaring at me when I hover over open windows on the taskbar, such as an explorer window or Firefox. Anything else I could try?– CerberusJan 2, 2019 at 15:42

Some of the instructions I found online seem to miss the detail of setting the Base type (Hex vs Decimal). It defaults to Hexadecimal
which may have unexpected results depending on what value you enter.
These steps worked for me to effectively disable the taskbar "preview thumbnails" from popping up in Windows 10:
Open Registry Editor.
Paste into regedit's "address bar" (under the menu bar), then hit Enter:
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced
In the right pane, if
ExtendedUIHoverTime
already exists, right-click and delete it.In the right pane, right-click a blank spot and choose
New
→DWORD
.Paste in the key name: (
ExtendedUIHoverTime
) and hit Enter.Double-click the new
ExtendedUIHoverTime
entry to open it.Under
Base
, clickDecimal
.In the
Value data
box, enter the delay desired before the preview pops up, in milliseconds.
For example, entering60000
makes it so you need to hover on the taskbar for a full minute before the annoying preview window pops up.Click OK and close the Registry Editor.
Reboot Windows to make the change take effect.
(Keyboard shortcut to reboot: +X→U→R) 😉

Wow a solution on my Windows 11 system that FINALLY does the trick! Thank you for sharing this much needed answer. It's incredible that Microsoft is this incompetent where even the "Disable Peek" option does nothing.– TwinbeeJan 12 at 0:03
