Redistributable packages are only required on machines for which VS2010 is not installed to provide the required battery life. If you check the Microsoft download page, for example:

Introductory paragraph:
The Microsoft Visual C ++ 2010 redistributable package installs the Visual C ++ Libraries runtime components needed to run applications developed using Visual C ++ on a computer that does not have Visual C ++ 2010 installed.
You only need to install the redistributable on the computers to which you deploy your application. Most likely, the new version of Windows Update has been updated to a later version than it is currently downloaded in the standalone version, but in general it should not cause any problems.
