Might anybody recall what this MS US is?

I located a reference recently (no luck today) and failed to make a notation believing I'd never forget it (especially since I had to make am exception on the space trailing semi-colon rule).

Stands for Bing Optimized IE9 / Bing Optimized IE8 I think which is a Microsoft Internet Explorer 8/9 edition optimized for Bing and MSN.

Many thanks.

So simple I never thought I'd forget it ;)

Wonder if it works with IE7?

"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; BRI/2; BOIE8;ENUS)"

You're welcome :)

I haven't seen any mentions of a Bing Optimized IE7.
A Google search for the above UA only gives 2 results, which makes me think it's a bogus (bot) one ... unless the browser is running in IE7 or IE8 Compatibility View/Browser Mode? Trident/4.0 is specific to IE8.

Trident Token

When the F12 developer tools are used to change the browser mode of Internet Explorer, the version token of the user-agent string is modified to appear so that the browser appears to be an earlier version. This is done to allow browser specific content to be served to Internet Explorer and is usually necessary only when websites have not been updated to reflect current versions of the browser.

When this happens, a Trident token is added to the user-agent string. This token includes a version number that enables you to identify the version of the browser, regardless of the current browser mode.

Edit:

When I run IE8 in Compatibility View mode I get this as UA:

Useragent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)

MSIE 7.0 & Trident/4.0 ...
