Miscellaneous computer tips – Volume 4

Tip #1:

If you have upgraded to Windows 10 Anniversary Update [v1607], you may come across the error “Unspecified Error” when you open File Explorer from the task bar or other locations.

To correct the problem, change the default view of File Explorer from “Quick Access” to “This PC”. To do so, go to Control Panel and click on the File Explorer Options applet. Change the “Open File Explorer to” option to “This PC”. Then you’ll be able to open File Explorer from the taskbar or elsewhere.

 

Tip #2:

One change in the Anniversary Update [v1607] of Windows 10 is that the User Access Control window [the window that pops up asking for your permission if you try to change, install or uninstall something] has changed. If you are use to the old UAC prompt, at least in v1607, you can revert back to the old prompt with this registry fix:

Windows Registry Editor Version 5.00

;

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\TestHooks]

“XamlCredUIAvailable”=dword:00000000

If you need to turn on the modern UI version in future, just set its value to 1.

 

Tip #3:

In their infinite ways, Microsoft pulled the popular screen capture tool out of OneNote 2016 so it can be a part of Windows 10. And if you don’t have Windows 10? At this time, the following registry fix should allow the screen capture to return to OneNote 2016.

Windows Registry Editor Version 5.00

;

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\OneNote\Options\Other]

“ScreenClippingShortcutKey”=dword:00000058

 

Note: As usual, before you apply the registry fixes, you should test, backup and verify the settings. Use at your own risk.

Computer Tip: Difference between User Access Control in Windows 7 & 8

User Access Control (UAC) is a security technology that first came with Windows Vista and evolved with subsequent Windows versions. It will help limit normal privileges available for local administrators as well as others with elevated levels. Over the recent versions, UAC has been tweaked to include less requests for access.

In windows 7, if set to never notify, UAC is actually disabled. With Windows 8, the Never notify setting does not disable the UAC but instead removes any prompts the user may receive. So when an application that is UAC aware makes a request for privilege elevation it will just happen automatically.

UAC is required for WinRT-based applications (such as Windows Store and modern apps) to execute. The application still has to request the elevation but will be approved.

An application in windows 8 that just assumes it has administrator privileges and doesn’t ask for elevation, it will ultimately fail.

To actually disable UAC in windows 8 you would have to modify the EnableLUA value in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System and set the value of 0. A reboot is but this will block the modern applications and is not a supported state of the OS.
