Recently downgraded to Windows 7 64 after having lag and shutter issues with FSX,  Should I have stuck with Windows 10 64 and just did re install ,   what have users noticed with clean install with Windows 10,  when I upgraded to Windows 10,  I did the free offer upgrade, rather than clean install,  Thanks,

I did an upgrade of Win 10 over Win 7 with no issues other than installing Win 10 drivers.  Not sure what caused your lag and stutter issues as many here are using Win10 without a hitch.

Same with me. Just had to update graphics drivers. All perfect.

I've never 'upgraded' an operating system - always a fresh install.  There is so much junk left in the registry after an upgrade that you're asking for trouble.  

 

Or perhaps it's just my CDO kicking in - I like things to be clean and fresh 

I'm running FSX in win10 pro 64 no issues other than a problem with RXP gauges. Been on Windows 10 for about 9 months. I went with the upgrade on win 7 then formated and did a clean install of win 10

I've been with Windows 10 from the beginning. I just updated Windows 7 Home, & everything has been perfect from day 1.

No formatting, or anything else. Maybe I've been lucky. :smile:   

After giving Windows 10 some time, and watching for the kinks to get worked out, I made the switch. Running both P3D v3 and X-Plane 10 flawlessly on Windows 10 at the moment.
