Not many people in this group seem very interested in disk image backups. I always have an image of my OS that is devoid of any vestiges of SmartSDR. Everytime a new version comes out, I use this image to load the latest version of SmartSDR. Since I have been following this method, I never have any thing but the latest version. It has been a wonderful method for me but I can't seem to engender any interest in hard drive images. Windows 7,8, and 10 have a wonderful Imaging program and have never had any problem with it.
