Bert,
Yes. If you have your data, then in many cases you can just restore the OS and just copy the data back on if needed. For example, with AC all you would have to do is copy the SQL Server database files back into the folder they should be in after re-installing AC. The only problem you'll have there is getting your settings back in place (i.e. icons on the desktop, etc., etc.).
For some situations, this will not be true. For example, Exchange Servers and Domain controllers. But that is another discussion.
Like yourself, I certainly make sure I have the install CD for Windows or at least an ISO file. This restore CD bull hockey can jump off a cliff.
