Restore Ghost 15 image your experience?

I have bought Ghost 15 and I have installed it on Windows 7.

 

Is it really possible to restore Windows using the Ghost image from the installed Ghost program, without having to close Windows and reboot first?

 

Everything looks fine and I really like Ghost, but I haven't needed to restore (and thus format the C drive) yet.

 

I would be happy to hear your oppinion.
