Although Flash offers update checks itself, but sadly many systems run outdated and insecure Flash Player versions. That is a huge security risk which must be eliminated.
Alternative Flash Player Auto-Updater let's you download and install the Flash Player without having to download Adobe's download manager - it downloads the latest version and asks you whether it should be installed or not.
You can choose to let it run at the start of Windows, this way you can be sure that your system will never run an outdated and extremely dangerous version of Flash Player. It supports both 32 and 64 bit Windows versions.
