Tweak Thumbnail Preview in Windows Vista

Wish to have larger Thumbnail Preview in Windows Vista?
Yes, now you can do it by editing the value in your Regedit Tools to make it more larger as you wish.

Here's what you can try:

1. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer
2. Create a DWORD Value and name it ThumbnailSize. Double-click the entry, select decimal and a number between 32 and 256. The default value for the thumbnail size is 100, if you would like a bigger size increase the number above 100, if you like smaller ones choose one below 100.
3. The new settings will become active after you restart your system.
