do you know this great free tool from Microsoft: psr.exe?
PSR stands for Problem Steps Recorder
as you can see from the name it is intended to create problem descriptions, but i found it very useful to also automatically document everything like Installation or configuration of software, doing PoC’s and so on.
psr.exe automatically creates a screenshot of every step you do and also gives you the ability to add comments. It then puts all the information together and creates a handy html file.
