Windows 10 Cop Out - Beware Media Creation Tool

[#1]

You many try the Windows 10 upgrade, decide it is not for you and want to rollback to your previous version of Windows ("cop-out").  But this does not always work, apparently.  Two less-obvious things to avoid are:

• Don't run the Media Creation Tool as this (allegedly) overwrites one of the folders you need to rollback.


• Don't change the user account structure by creating new accounts or deleting old ones as the computer gets confused if you do.

And i thought it was the Computer that confused  us ,, Not the other way round lol 
yes the media creation tool makes a clean install no rollback folder

No, you misunderstand.  Even if you use the Media Creation Tool to create media which you use on another computer or never use at all, the mere act of running it overwrites one of the folders needed for the rollback.
