I upgraded from Win 7 pro to Win 10 because my laptop (Sony Vaio) was painfully slow to start up and close down (aprox. 5-6 minutes each process); now
it is even slower, and windows keeps trying to install TrayApp.msi (what is that?) but can't find it. Today windows is trying to install also MarketResearch.msi (???)
but can't find the source either. Anybody with an answer to this.
