#310
Since the number will change from 1511 to 1607 that should properly be called a Version Upgrade as has been the history of newer versions for quite some time. Doing the Upgrade on more than 30 computers from the first version last July to 1511 in November has never deleted the files and programs on those computers except for a few programs that simply won't run on Win10. Doing a Clean Install will delete everything from the HDD/Hard Disk Drive [or SSD if using that].
