If you are still contemplating removing X3, following your completion of the upgrade, I believe that will likely cause some glitches - it has been reported in other past threads that if one chooses to uninstall a prior release that the prior release is better uninstalled THEN the newer release should be installed.
 
And, I believe that if things were inadvertently/unknowingly done the other way around, and glitches DID appear, that the fix would be to simply do the install of the newer release again.
 
Sorry I don't have more details, or a 'for sure' stamp for the above.  I still have releases going back to X1 all still installed, so I didn't pay that much attention to the other posts I was referencing, and also they were from some time ago.
 
If anyone else can substantiate or correct my thoughts above, please do so, and thanks.

I still have 8.5 installed alongside X1 and X3e.  Some plugins that seem to come and go come in handy when they don't go poof.

I did uninstall X3 and did not get rid of shared files--Say no to all.
I think that Is the key.
Also i got rid of duplicate files with cc cleaner,but make sure it Is done slowly.
 
I have no glitches and all is well so far
Just keeping things tidy
