I just checked on a core I built to make sure it was not added to my LdAppl3 file, it is not, it appears by default it is listed under "Custom Data"
If it is not in yours, you can add this line to the ldappl3.template and then go into SLM and click on then "make available to clients" icon
KEY=HKLM,Software\Microsoft\Internet Explorer,Version,Custom Data - Internet Explorer - Version
I think I found it!
I was looking for something like Microsoft Internet Explorer ... or Internet Explorer....
but I found it as Windows Internet Explorer ...
but that value only detects IE 7 or higher.
is there a similar option to create a query for detecting PCs with IE6 or lower version? other than following the instructions in the post above regarding ldappl3.
Since my lasty post, I have found that by default, it should show up in your custom data without the need to modify anything
