4. Idea. Uninstalled Google Chrome and delete related registry keys:

- Verified the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command and it set
correctly to the value of another Vista box with IE 8:

"C:\Program Files\Internet Explorer\iexplore.exe" -nohome

- Internet Explorer is set as the default program for HTM and HTML
- Got a process monitor from Outlook while reproducing the problem.
- Determined you had previously installed the Google Chrome Browser - it changed the HKEY_Classes_Root for .HTML and .HTM from "@=htmlfile" to "@=ChromeHTML".

Original key in the machine:
----------------------------------------------
[HKEY_CLASSES_ROOT\.html]
@="ChromeHTML"
"Content Type"="text/html"
"PerceivedType"="text"

[HKEY_CLASSES_ROOT\.html\OpenWithList]

[HKEY_CLASSES_ROOT\.html\PersistentHandler]
@="{eec97550-47a9-11cf-b952-00aa0051fe20}"


- Changed the @="ChromeHTML" to @="htmlfile"

[HKEY_CLASSES_ROOT\.html]
@="htmlfile"
"Content Type"="text/html"
"PerceivedType"="text"

Same for .htm

[HKEY_CLASSES_ROOT\.htm]
@="htmlfile"

- We also removed the Google Chrome from the machine.
