Q: Boot Camp Control Panel Windows 7 64Bit

You will need to reset SMC.

Are the Bootcamp Drives installed on the Windows side? Do you have a Boot Camp option in Control Panel -> System?

Please download System requirements to install Windows on your Mac via Boot Camp - Apple Support for your specific Mac year/model. Once you have the appropriate drivers then Boot Camp: Install or repair Boot Camp drivers.

Post back, if you still run into issues.

Can you please elaborate on what you mean by fresh W7 64 Pro? Is this a re-installation on the same partition? Was the old installation deleted via BCA?

Do you have a Boot Camp option in Control Panel -> System? Does that behave any differently?

When the Boot Camp drivers are installed, they are installed for all users silently, because it is done as a part of the Windows installation, before any user accounts have been created.

The following snippet is from the AutoUnattend.xml on the USB Installer. See the highlighted part. This is from a W8 USB Installer built using BCA and an W8.1 64-bit ISO.

Can you check your Windows Installer USB for this file? You may not have one for W7 64-bit. This is what I have on a W7 USB.

The initial silent install for all users failed. . But good to know a potential work-around. Thanks.

The Control Panel issue is specific to Windows. Yosemite re-installation may not change the behavior.
