For those who don't know how to turn off all the spyware in W10 you can use this;https://www.oo-software.com/en/shutup10

I have my doubts that Microsoft will ever get this right. Yet again another problem. If you use the Windows built-in zip function, after zip files are extracted to a folder the files are deleted. 3rd party zip file programs are not affected

Set default mic in W10; https://answers.microsoft.com/en-us/windows/forum/windows_10-power/how-to-set-default-microphone/ae299765-769d-43cd-869c-c4d1e9103d40

Depends what your UAC(user account control) settings are,it's usually in "username/AppData/Local/Activision/CoDWaW Make sure you have "show hidden files and folders" in folder options checked

Microsoft says they have found the problem; https://www.guru3d.com/news-story/microsoft-resolves-issue-with-windows-10-disappearing-files.html

Update has been pulled until a fix is implemented. It appears that if your documents (pictures, music, video's etc.) are not also in OneDrive, that they will be deleted and unrecoverable after the update

Windows 10 October 2018 update (1809) is out if anyone wants it; https://www.microsoft.com/en-us/software-download/windows10

Watched the video, seemed pretty straight forward. What part of the procedure are you having problems with?

Make sure "stereo mix" is enabled.

Make sure you have a headset and mic plugged in. Are you receiving any DirectX errors?

If you check "perform a clean installation" when installing Nvidia drivers, all control panel settings will be at their defaults.

Check your mouse pointer settings, Windows 10 usually sets some settings to defaults after some updates. Also try switching between windowed mode and full screen mode (alt + enter) and see if it goes away.

Are you sure it's a G602?
