I bet many of you, like me, performed system maintenance duties for your family. Last week my mom complained that her Windows 10 PC was extremely sluggish. For example, when she opened Microsoft Edge - which I consider to be the best and the most secure web browser on the market for nontech savvy folks - it took round about 10-20 seconds for the browser to become responsive. I had no choice but to investigate. After a couple of minutes with SysInternals tools, I was able to determine the cause and to come up with a workaround.
