An easier method would also be to set up a virtual machine and install your known-good operating system and programs into the virtual machine. Then save that system state so you have an always-good, known configuration. Now, do your work in that virtual machine and when done and when you’ve moved any created data files out of the virtual machine to a safe place you can close down the virtual machine and anything and everything on it would disappear. The next day you start over again with a new copy of the original virtual machine. If you do this then you can be a bit more bold in what you do because you know that whatever got onto your computer will be gone when you close the virtual machine. Again, not perfect but not bad as an approach.
