Enable/Disable Windows 10 “tray” notification area icons

Posted by jpluimers on 2019/08/19

It looks like they reorganised the way you can enable/disable the Windows Notification Area icons (often called “Icon Tray”) in Windows 10.

Up until Windows 8.1, you could run this:

%SystemRoot%\System32\rundll32.exe shell32.dll,Options_RunDLL 5

There you would end up editing the application specific icons.

As of Windows 10, you need to:

  1. Run %SystemRoot%\System32\rundll32.exe shell32.dll,Options_RunDLL 6
  2. Click on “Select which icons appear on the task bar” (or Dutch “Selecteren welke pictogrammen op de taakbalk worden weergegeven”)

So both the index changed, and you need an extra click to get at the application specific icons.

Further more, you can now only turn them on or off, where up until Windows 8.1, you could also choose only show notifications. I think on means only show notifications as for instance the Java Updater with a setting on on Windows 10 disappears after a Java Update has been installed, whereas on Windows 8.1 it would stay unless you switched from on to only show notifications.

The above commands are based on [WayBack] Create Direct Shortcut for “Notification Area Icons” in Windows Vista and Later – AskVG and

Windows: running “mklink” as Administrator “You do not have sufficient privilege to perform this operation.”

Posted by jpluimers on 2019/08/19

Via “mklink” “You do not have sufficient privilege to perform this operation.”:

The [WayBackmklink tool can create NTFS links so multiple directory entries point to the same object.

It requires the [WayBackSeCreateSymbolicLinkPrivilege (in English Windows versions [WayBack] “Create symbolic links”) which is by default not granted to users as it can expose security vulnerabilities.

Even if a user in the Windows Administrators group has the privilege, it still cannot be executed from a regular command-prompt:

C:\Users\Develope>mklink "%temp%\Recycler" c:\$RECYCLE.BIN
You do not have sufficient privilege to perform this operation.

If you grant a regular user the privilege you can execute if from a regular command prompt.

However, as member of the Administrators group, you have to run this from an elevated command-prompt:

C:\Windows\system32>mklink "%temp%\Recycler" c:\$RECYCLE.BIN
symbolic link created for C:\Users\Developer\AppData\Local\Temp\Recycler <<===>> c:\$RECYCLE.BIN

The reason is that members of the Administrators group get two security tokens when they logon: an elevated full-access token and a regular filtered access token.

They key here are the words full-access and filtered: the elevated token gets more access permissions than the account is configured for, but the regular token gets less access permissions than the account is configured for.

This means that a standard command prompt will not get all the access you might exec, as the regular token is the access permissions minus the filtered permissions.

By now you probably guessed that – despite the documentation [WayBack] Windows Vista Application Development Requirements for User Account Control Compatibility leaving out SeCreateSymbolicLinkPrivilege – that is actually part of the filter. So the regular command-prompt lacks the SeCreateSymbolicLinkPrivilege permission and gives you an error message when executing mklink.

This is opposite to a regular user: if you grant it the “Create Symbolic Links” any command-prompt will get the SeCreateSymbolicLinkPrivilege permission.
