This helps to determine how an install changes the registry. Most of the time I’ll just export out a portion of the registry, but in this example, I’m exporting out the whole registry.
regedit /e before.reg
Then install the program and then run the following
regedit /e after.reg
fc /u before.reg after.reg >changes.txt
Now open the changes.txt file to view the changes to the registry.
There is also a REG command I’ve not used before but the syntax to compare a section and subkeys of the registry on a machine named FRED with the current machine would be:
REG COMPARE FREDHKLMSoftwareNetSoft . /s
