Hi,
a small registry trick which can be used to adjust this hover delay time. You can set the delay time to get the thumbnail faster or slower.
1. Type regedit in RUN or Start Menu Searchbox and press Enter. It'll open Registry Editor.
2. Now go to following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
3. In right-side pane, create a new DWORD value ExtendedUIHoverTime
4. Now you'll need to set its value to your desired delay time. Double-click on it and select "Base" as Decimal and
enter the desired value. Remember the value should be given in milliseconds.
5. That's it. Log off or restart your system.
Regards,
D. Wu
