To setup a proxy exclusion so you do not have to disable the accelerator when you want to do a Windows update, simply right click on the accelerator icon and select "Settings".
Under the settings menu, select the "Proxy Exclusion" tab.
Select, "Specify a proxy exclusion list" and put in:
http://Windowsupdate.microsoft.com;
http://www.windowsupdate.com;
http://update.microsoft.com
Click "OK"
NOTE: If you do not want the accelerator to be activated on a particular site, enter the URL in this Proxy Exclusion section.
Secure websites that begin with: https:// are automatically excluded from web acceleration.
