You might find this a helpful tip (perhaps for advanced users only)...
If (like me) you normally only really use SandBoxie under certain web browsing conditions (i.e. visiting unknown web sites...installing software and so on), you obviously don't want the SandBoxie system driver (which takes up resources) running unnecessarily.
By default, SandBoxie installs it's driver when your PC is booting (which has to hook into all sorts of Windows drivers) and, if you use SandBoxie ALL the time, this is good
However, to avoid this default, do this:
1. Fire up the Windows 'Control Panel' (and you must have 'Admin' rights to proceed further)
2. Go to 'Administrative Tools'
3. Click on 'Services'
4. Scroll down to 'Sandboxie Service' and change its state from 'Automatic' to 'Manual'
If it is, stop SandBoxie Control Panel from starting at boot up (use msconfig).
From (at least v3.22), when you fire up SandBoxie, the required driver is automatically loaded so there is no longer any need to load the driver at boot time.
Hope this helps.
