make a BACKUP!!!!!
All you need to do is make a folder in windows called "backup" copy the regedit
files into there, so if it goes a bit pear shaped then you have the original setup.
Thanks to Sanj for pointing out I omitted this info.
Desktop Icon Redraw
(Windows 9x and NT)If you desktop icons are redrawing too frequently, it could be because
the icon cache is full. Try increasing the size by changing this setting.
Open your registry and find the key below.
Create a new string value, or modify the existing value, called "Max Cached
Icons" and set it to "8192". This will increase the icon cache to 8MB
Restart Windows for the change to take effect.
Value Name: Max Cached Icons
Data Type: REG_SZ (String Value)
