There's been a fair amount of discussion both in private emails and on the MSHelp3 Yahoo! group about the pros and cons of requiring signed .cab files for silent installs with the new Help system.
As anyone who's been using Vista and Windows 7 knows, security is a pretty big deal these days despite all the headaches people feel it causes. Without security, you'll have even bigger headaches before you know it!
Before long I will be posting some background on some of our thinking around this requirement. In the meantime, however, I wanted to make sure that those who have need of some of the basic details around signing their cab files have access to the general details.
In addition, I'm providing some information about what you can do to test this out without having to purchase a certificate - you can create your own test certificate, which you can use for signing purpsoses on your own machine.
Here's a page (again in the Links section, as well) describing the basic process. Have fun!
