The mouse that was sent was used which would be fine on a repaired PC if it didn't look like it contained whatever the last user ate for the last year in the cracks and seems of the mouse.Still testing all the USB ports but it seems one of them may not be working.  I have to find another cable to test and be sure.The PC would not take any Windows updates initially.  There was a conflict between one of the of the major Windows updates and the Sure Start feature of the BIOS.  Tried the fix for the Windows update written on the HP site by disabling the Sure Start feature. The PC came with an "Institutional" version of Windows.  Ended up installing a different version of Windows 10 Pro which later was able to install all of the updates.The wireless adaptor is not the greatest.  It is wireless N.  It does have to receive router signal from 50ft away and through a few walls.  So, that's just the way its going to work.  3/4 of the time, its OK.
