Windows 10 task bar thumbnail preview

[tilieve]

My task bar lost the ability to show preview of pages if i have multiple window opened. for example, if I have 1 chrome window and 2 file explorer window open, task bar can only show the preview of the chrome window but icon for the file explorer. This happened after i installed a windows 10 update(feature update ver.1903). I also checked the task bar settings and windows performance and appearance setting. Any help?

Start/Search > type: Performance > pick: "Adjust the appearance and performance of Windows"

A panel will show. On it, make sure all check boxes are checked, click on OK.

Restart the system and you should be good

those are all checked, every-single box.

I saw some guide about modify the register file to give the thumbnail a different size or delay time.Was thinking of maybe in one of those register setting, it limits my thumbnail preview amount for each app to one.

Good thinking. Another thing to try is to check if the Group Policy "Turn off taskbar thumbnail" is enabled, and if so, disable it, and restart your PC.

Interesting. I have it on my side

 

 

And why your folder icons on the tree are a mixed from Windows 2000 and Windows 10?

Did you happen to use a software that does "tweaks" on the system? Or used a Start Menu replacement program? If so, it probably replaced system files, and you have this broken mess.

I wasn't using any of those program. The mess might came from a script I ran to get gpedit on my windows since mine is a windows home edition. 

here is the script:

     

@echo off 
pushd "%~dp0" 

dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientExtensions-Package~3*.mum >List.txt 
dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientTools-Package~3*.mum >>List.txt 

for /f %%i in ('findstr /i . List.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i" 
pause

 

It might also be that when I added an ssd to my pc, I forgot to uninstall windows from my old drive, which is also windows 10(the files disappeared though). 

So, in this case, if I do a clean system install, shall I back up my windows settings?
