Hi All I have a friends computer - hard disk is running 99 - 100% utilization all the time.... Everything you do on it is painful. I booted into Safe Mode and same issue. So, started by applying all of the firmware updates from his vendor (ACER)... then updated Windows .... here is my issue - when I got into look at the Settings - Update it tells me release 1511 is there ... but I get no link to download it or run it. So I pulled down what I thought was the update from the MS Catalog copied it to his machine and it says that it is not compatible with his machine. He has Win 10 home 64 bit... upgraded from Win 7. My thought is he brought the hard drive issue through the upgrade somehow... after the firmware it now runs 80% of the time so slightly better ... but wanted to get the latest version of Windows on too. It is possible that what I pulled from the catalog is an update to 1511 .... but the update page says its there waiting. Can someone tell me how to get it and install it?
