Freeware/Open Source Software for All Needs
And some affordable *Commercial ones

After having spent a lot of dollars and euros in buying software "for life" that eventually expired when I bought a new laptop I decided to find and use software that was equal in sophistication as the equivalent commercial one but was free and worked as successfully as the paid for software. I have selected below software for a variety of needs that is either free or open source (free and usually continuously developed) and has no limitations or expiration date or commercial but affordable and with no limitation of the purchased license. The pieces of software are here selected not for advertising purposes but only because they work fine and in most cases I use them with Windows 11. However some are also available for other platforms such as Mac OS X, Linux, Chrome OS etc and in many world languages.
