I had a chat with Horizon support and this is a list of changes from version 8 to version 9. I had expressed concern that by upgrading to a new release I might be upgrading to a buggy program. I mentioned that I generally prefer to wait a few months before upgrading so as to avoid some/most (hopefully) of the bugs. Below is what I was told. 1 - v9 is not a new program, but an upgraded version of the one I currently own. 2 - RollBack Rx V9 has made some significant changes from the previous version 8.1. Version 8.1 had an integrated Drive imaging application for clients that wanted to be able to have true hardware disaster recovery. It was known as the "Drive Image" feature in Version 8.1. In RollBack Rx Version 9.x they separated the Drive Cloning capabilities and introduced it as a new product "Drive Cloner Rx". It supposedly will complete head on with products such as Ghost, Acronis and other hard disk imaging and cloning products that are available. Horizon will continue to grow this product by adding features while maintaining a low cost point for its clients that need a cost effective hard drive imaging application. 3 - Rollback Rx v9 is easier for large educational and corporate clients to use the Remote Management Console. Horizon has removed the separate pricing of the "Enterprise" version of the software and now provide the RMC as a free add-on. All RollBack Rx users that have more than 3 networked PC's can now use the RMC to remotely manage their PC's. 4 - The nagging pop ups that appeared every time the application was launched whereby shield.exe and netreg.exe would display certificate warnings etc have been removed 5 - Some significant changes have been made to make RollBack Rx quicker to boot up and work with Windows Vista, both 32 and 64 bit.
