How do I know if a software is installed on my computer?
For a list of programs installed on your computer, you can browse Start Menu> All Programs but you will find a list clearer and often more fully in Start Menu Panel> Add / Remove Programs. This is particularly useful if you do not remember having installed software, if you are not the only one user can install programs or if your computer was delivered with software pre-installed in order to implement the necessary security fixes.
How to determine the version number of software?
To find the version number of software, it usually suffices to look at the menu "Help" or "?", Then choose "About" or "Version": this version number is usually in the form a series of numbers separated by periods (for example: Internet Explorer 7.0.5730.11). It is recommended to know the version numbers of its main software to ascertain if they are concerned at the announcement of a security hole and be able to apply the patch corresponding to the correct version of the software.
