Secunia APS has reported that over 20% of applications which run on Windows are missing security patches.

Jakob Balle who is the manager of Secunia’s development said, “More than 20% of all applications installed on users’ PCs have known security flaws, but the users have yet to install the patch provided by the vendor of [the] product.” This figure was based on 4,200 different programs.

The ratio was an improvement compared to a previous report that Secunia PSI scanned.

PSI runs on four different operating systems which are Windows 2000, XP, Vista, and Server 2003.
