Upcoming Creators Update Sometime next month a Few Questions

Hi All

As you probably know I just recently got my very very first SSD, trying to limit amount of writes to it, so wondering how I handle Creators update install, Option A over the top of 1607 via WIndows update, and keep everything, Option B: start the upgrade, and select keep nothing, or Option C, Complete delete of paritions and another clean install of Creators update.

Data is on secondary 2tb hard drive

All depends on how much of your settings and installed programs/apps you want to keep. I'm going to download the ISO file and save it to my NAS. Then on each of my dozen or so computers on my network mount the ISO file and run setup.exe to do an in-place upgrade without having to download it via Windows update on each computer. The main issue is going to be to get it done before Windows update does it for me anyway.

Well actually wouldn't mind keeping all the current settings, and installed programs, Inplace upgrade might be best way to go then, don't have a NAS here as yet, but probably will download the ISO and save it to one of the flash drives, and tackle it that way most likely.

Other upstairs system running Avast currently, probably will do proper removal of that prior to doing the upgrade, as might go smoother that way.

This one currently running Windows Defender, and Malwarebytes 3 free, (just have to system specs again soon here)
