Ok so here's my windows 10 journey.
Tried the first method and tried several times but had download files failed messages.
Used the second method and off we go.
Installs quite painlessly.
However it didn't port over my Nvidia graphics card drivers.
So I download the driver package for my specific card and express install.
Yay I can now run my screen at it's proper resolution.
Photoshop runs fine
Video runs fine. . . but wait where's the sound ????
Ah, it's not selected to the front headphone jack, had that before. . . into settings
Huh ??? no headphone jack to be selected. Just a bunch of Nvidia HDMI ports available.
OK Ill just download the realtek drivers for my PC install them and that will override the Nvidia ports
NOPE!!!
Uninstall the Nvidia drivers, Nope the sound settings are all still NvidiaHDMI
install the realtek again hoping they can now overwrite the Nvidia settings
Nope
Grrrrrr
off the the mighty interweb, nope not much help there.
So bugger it reset Windows
So I lose all my applications but restore the beast to stock settings
yay I now have sound
Reinstall Nvidia graphics settings manually not selecting the sound options
all working fine now
Just have to reinstall all my software.
sigh
It would have been a painless experience if Nvidia hadn't mucked it up.
Still I'm liking 10 so far
