Have had a Win7 system up an running for 4 years. About once a year I do an Upgrade Repair.
Everything has gone well save for this last try!
About 2/3 the way thru, in the "expanding windows segment, I get a notice... "could not retrieve information about disks on this computer"! Game over!
Thought it may have been the Virtual Disk service which was on "manual"... changed it to "auto" but still the same result.
Would try a New Install but the glitches are not that critical! Reinstalling a 100 plus programs and transferring thousands of data files is not terribly appealing!
Would just like to get the Upgrade Repair working!
