One warning about Ultraedit html defaults and the registry: The wrong file association will remove your ability to open embedded links in Office and Outlook 2007.
I have a new Win7 Pro box. Installed a new copy of Office 2007. It is a generic, all defaults accepted installation. Next in was Firefox. Last was the UltraEdit / UltraCompare / UltraSentry. I found I could no longer open embedded links. The error message was:
This operation has been canceled due to restrictions in effect on this computer. Please contact your administrator.
If you do a search, the most common reason for this problem is that Firefox ends up being the default browser for all html links and you have to restore MSIE as the default. Should this not work, you will have to edit the registry and correct it. Google's Chrome browser also causes the problem. You can find instructions for a fix at: http://www.slipstick.com/problems/link_restrict.htm
Went through the procedures and they didn't work and had to edit the registry. Note: please back up your registry first. Went to the following keys:
HKEY_CURRENT_USER\Software\Classes\.html and .htm (.shtml if that key exists)
Change the default value - mine was UltraEdit - to htmlfile in all 1-3 keys and save the changes. You should be immediately able to click the links.
The gotcha here was the opening screen of UltraEdit, which by default selects it as the default editor for literally everything. I accepted the defaults (yes, it was dumb) and Win7 updated the registry. So be careful the first time you fire up UltraEdit in Win7, it may eliminate your ability to open links in Office 2007 documents and e-mails.
