I am using Macrium Reflect Free for disk imaging of the OS. Then I install software, a, b and c, (in this order/chronologically) and if it runs fine and all is good a new image is made after each piece, a, b and c. This goes on and on until I find there is software that I do not want any more. Removing it leaves traces and the OS is (often) not what it was before. How can I go back in time and only remove a particular software, let's say a, but still keep the other, newer software, here b and c, that was installed later on? Thank you for any help with this, not sure if something like this exists, I really mean to ask this question, so sorry if the answer is obvious, not too knowledgeable concerning this type of imaging. If something like this does not exists as a software, like Macrium Free, is there another method, perhaps involving several applications to achieve the wanted result, the complete removal of software at a later point in time without touching the other current system files and installations. Please help me with this, thank you.
