As Mitchell has said mate we have all been there done that more times than I can count. Windows I find has some weird idiosyncrasies that cannot be explained at times.
A good example is recently the USB ports stopped working on my main machine and the culprit - the Samsung Magician software - uninstalled that and ports all came back - work that one out because it was way beyond me and any logical reasoning.
It was sheer luck another member had seen this before and let me know. So it has happened that you have struck a bug and by luck sorted the issue.
