I installed a little ‘patch’ on my computer today for a program I was running which disabled itself.
Before doing so, I saved my registry subtrees as text files. Then I installed said ‘patch’.
Once it was installed, I saved all the registry files again and ran a text comparator. The standard Microsoft text comparator program would be WinDiff. I used BeyondCompare though because I’ve been using it at work and found it to be favorable.
In BeyondCompare, I could see exactly what keys had been changed by the ‘patch’. It was pretty cool because this not only shows me what the ‘patch’ did, but also gives me a little insight into how the original program works.
Most of you probably have no idea what I just said, but I’m a programmer and these things amuse me.
