I wasn't getting any notification that the upgrade was ready so I used the Media Creation tool and set it to upgrade. It downloaded very fast and installed in a reasonable time. Since I had done an 8.1 image backup just previously, I went ahead and got rid of the Windows.old folder through CCleaner. I did have a few issues.
My sound worked fine at first but then went out. I uninstalled the sound card through Device Manager but did not delete the driver software. It reinstalled the card immediately and it works fine.
My screen resolution was screwed up. The desktop picture was smaller and centered in the screen and fonts were too small and sometimes cut off at the bottom. I checked the resolution settings and it was at 2544 X 1431 which my monitor doesn't even support. I set it to 1920 X 1080 and things went back to normal.
After getting the resolution set, my text looked pretty blurry so I had to go through the clearType wizard and set that up.
My Gigabyte utility, EasyTune6, which I was using to control CPU fan speed does not work in Windows 10. I went and got the latest version and it still doesn't work. It will not load and gives a message about a driver error. Right now I have no fan control except what is given in the BIOS and that makes the fan run too fast and noisy.
Everything else is fine. All my files were kept and all my programs run fine. Even the Free Bitdefender AV is working. Classic Shell works perfectly as well.
I also used a program called winaerotweaker to remove the shortcut arrows from the desktop icons and to enable colored title bars for my programs. It worked perfectly and there are other tweaks that can be applied as well.
I'm up and running but I do think the upgrade could have gone better.
