Hello,
I started with a fully functional Dell Latitude E4310 (circa 2011) with Windows 7 pro. Microsoft get windows 10 app came up all green for upgrading to Windows 10. Upgraded, and the laptop became very slow. It's basically become unusable. Before you ask - it has 8Gb RAM.
Investigation (too little too late):
I'm missing one driver after upgrading.
Device type: Other devices
Manufacturer: Unknown
Location: on PCI Express Root Complex
No idea what this device might be or if it's related to my performance issues. Should have made a list before upgrading.
Now (again, too little too late), I check Dell's website - for drivers. They have no plans to support Latitude E4310 with Windows 10.
So. Other than _running_ back to Windows 7 as fast as I can, does anyone have any suggestions?
