As of five days ago, my Win 7 laptop started running constamtly. This morning, I realized that Windows Live Mesh was the culprit. It deposited 35,215 "Windows Live Mesh" files into the recycle bin over a five day period. I uninstalled WLM and cleaned out the recycle bin, but then I discovered that my desktop Win 7 machine had developed the same problem ... 19,614 files deposited in the recycle bin over two days. These are all PDFs by the way. I cannot find anything on Microsoft's website, or using a broad Google search, that even acknowledges the problem. I also searched for a solution on Experts Exchange, without any success.
