Important: Be advised that it is reported that installing MS12-058 (KB2740358) means Rollup 4 will be installed on your system. This applies to manual installations but updates installed through Windows Update / WSUS as well, which might pose a challenge (or better, dilemma) for security departments.

Those who use WSUS to deploy security updates or manually apply MS12-058 will be inadvertently applying Exchange 2010 SP2 RU4 as the security

As of Rollup 4, it’s no longer required to disable/re-enable Forefront Protection for Exchange using the fscutility to be able to install the Rollup properly. However, if you want to remain in control, you can disable Forefront before installing the Rollup using fscutility /disable and re-enable it afterwards using fscutility /enable.

Note that Rollups are cumulative, i.e. they contain fixes released in earlier Rollups for the same product level (RTM, SPx). This means you don’t need to install previous Rollups during a fresh installation but can start with the latest Rollup.

As with any Hotfix, Rollup or Service Pack, I’d recommend to thoroughly test this rollup in a test and acceptance environment first, prior to implementing it in production.
