JSI Tip 5445. How do I configure the size of a Windows XP thumbnail image?

You can configure the thumbnail image size using the Registry Editor:

1. Navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer.

2. Add a ThumbnailSize Value Name, a REG_DWORD data type, and set the data value to a number between 32 (small) and 256 (large), using the Decimal radix.

NOTE: The number should be a multiple of 16.

NOTE: To configure this for all users, use the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer key instead.
