I have been submitting my feedback on Windows 10 Tech Preview Build: 9926.
The previous builds were heading in the right direction,
but the latest build 9926 has me a bit off.
I have decided to keep a log of all this sent feedback.
Hopefully Microsoft Build team will take it into consideration.

I will be documenting all my feedback I am sending to Microsoft
through the Windows Feedback app from within Windows 10 Tech Preview right here in this post.

Driver: SBXF_PCDRV_L11_2_30_0004.
This card had no sound, Although it appeared to work fine in Windows 10 9926.
Device Manager reported the device working properly.
Properties sound meter showed working.
Just no sound coming through the headphones.
After an update yesterday 03/03/2015 the sound just started working.
However the Creative Audio Control Panel still does not.
I’m happy the card sounds great.

Windows Update Windows 10 build 9926 : 03/01/2015
Keeps automatically installing updates I do not want. Specifically Nvidia Geforce Drivers,
Which I would rather manually download & install this, there are features I want, and do not want.
Please give us more control with updates, specifiaclly 3rd party drivers, and software.
the old method in Windows 7 was much better. I could Hide the updates I do not want windows update to control.
Hide, Unhide, Choose, View, Manually install updates, turn off automatic updates,
Windows Updates is force updating my hardware, and software. need more windows update control.

A would make a context menu of the control panel items,
Now I cannot customize the menu.
I would like to see custom context menu on start.
