If you have a habit of opening lot of windows side by side then resizing them each time they open would be an issue for you.
Whenever we open up an application it opens with the size it was closed but if you are required to change the size of the window quite often then this tool called AutoSizer is for you. AutoSizer automatically resizes programs for you, keeping them at a specific size or keeping them maximized.
AutoSizer remembers the size settings for each of your programs and opens it in the same size specified. For example if you wish to use Windows Media Player in a small window then this tool will run it in that size only whenever you start the player.
The tool works with most of the programs and also supports all versions of the Windows.
