Want to control the size of the Thumbnails view in My Computer?

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\Explorer
Name: ThumbnailSize
Type: REG_DWORD
Value: 25-256
25 is smallest thumbnails and 256 is largest. Experiment for your workstation and set it to what works best for you.

Find that you need more space for thumbnails and would like to turn the file names off? Hold down shift when you open a folder or when you switch into thumbnail view. This will turn of the file names, giving more space for the thumbnails. Doing it again turns them back on.
