My useful utilities and favourite programs to make everyday life that bit easier

Most of these are Windows based, but some are cross-platform. They are mainly free tools, but paid ones have been marked accordingly. Freemium tools have a free version but have a full version for a price. Tools are in no particular order

Utilities

• Windows Sysinternals - the swiss-army knife of Windows tools: https://docs.microsoft.com/en-us/sysinternals/ (Free)
• Listary Pro - a spotlight style search tool for Windows: http://www.listary.com/pro (Freemium)
• Ditto - clipboard management tool: http://ditto-cp.sourceforge.net/ (Free)
• Cmder/ComEmu - make command prompt suck less: http://cmder.net/ (Free)
• Bvckup 2 - the best backup program I've tried: https://bvckup2.com/ (Paid)
