Thumbnail preview disappear too fast in the task bar and Alt + Tab

Hello everyone,

I have recently reinstalled my laptop with a windows 7 home version.
When i put my mouse on the different icons in the taskbar to check the windows opened it disapear very very fast and even sometimes when i'm fast enough to click on a thumbnail to change window, it's not taking that click.

I also have the same issue with the Alt+Tab feature, after 3 tabs everything disappear.

I have done some researches :
Editing the RegistryKey : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\ThumbnailLivePreviewHoverTime
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AltTab

Nothing changed , i have no idea if it can helps but i have a DELL xps 15z.

Best regards,
Clément

1. shut down the laptop
2. remove the power supply and the battery
3. press and hold the power button 2-3 times and keep it pressed for 1-2 seconds --- obviously the laptop will not start!
4. plug in the battery and the power supply, start the laptop and check if the problem is gone

Hello Cyanna,

I already saw that solution on internet, the problem is that i can't remove the battery from the laptop like this...

Unfortunately i can't do that as i replaced my hard drive disk 1 month ago and i destroyed one of the screw ...

There is no other solution to that ? Maybe empty the battery then try your process ?

What do you think ?
