Okay, 

Solution 1) "resolve QB DT performance issues: Manage  your computers"

This deals with the solutions I have already addressed: 

Its NOT hardware. 

Its NOT ram. 

Its NOT virtual memory. 

Its NOT competing programs.  When we start up the computer in the morning there are no other programs running.  We start QB and its the dog in the house here, not the other sleeping puppies. 

Its NOT the OS, Win 7 64 bit is an excellent OS, and forget about Win 10 (too many new child issues). 

Its NOT running on a terminal server.  And, we only got one user. 

Its NOT were we run the program or store it, the Samsung SDD drive is perfect. 

Its NOT the data folder.  Been using every QB on these drives and older drives. 

When you "upgrade" from QB verison to QB version your software handles that.

So far, all of the suggestions have not helped, and the suggestions are generic (no offense).

Understand I have been using QB since the days of DOS (google DOS).
