   Hi All, especially Paul,   
      
   Would you double check my File Sharing Network Optimization   
   .reg for typos and if I did anything stupid.   
      
   This is aimed at a Windows 11 Pro being set up as a file   
   server, Calendar sharing based on MySQL, and QuickBooks company   
   file sharing   
      
   Many thanks,   
   -T   
      
   When we ask for advice, we are usually looking for an accomplice.
