Advanced Tip: Finding and Uninstalling a HotFix From PowerShell

Warning: Use this trick at your own risk, uninstalling the wrong hot fixes on your system can cause problems.

There are several ways to find the hotfixes from the GUI tools on your system, such as the Windows Update GUI.  I generally like to use PowerShell only tricks, but this one is a hybrid. It uses a utility called WUSA to uninstall the hotfix.

To uninstall a hotfix on your system, you need to know its KB number.  You can use this technique to test if it exists and then uninstall it. All you have to do is change the KB number in the $A variable.

$a="11111111";$b="KB"+$a;$c=Get-HotFix|Where-Object HotFixID -eq $b;if(![string]::IsNullOrEmpty($c)){wusa /uninstall /kb:$a}

Looking for PowerShell equivalents for older console network commands such as IPCONFIG. The IPCONFIG command is used for displaying IP address information (including the subnet mask, and gateway) for the local NIC adapter attached to the computer.

PowerShell: Get-NetIPConfiguration or Get-NetIPAddress

Examples:

  • Get-NetIPConfiguration
  • Get-NetIPAddress | Sort-Object InterfaceIndex | Format-Table InterfaceIndex,InterfaceAlias,AddressFamily,IPAddress,PrefixLength -Autosize
  • Get-NetIPAddress | Where-Object AddressFamily -eq IPv6 | Format-Table –AutoSize

Window 10: File Explorers New ‘Quick Access’ Menu

Quick Access folders

The File Explorer has a new feature called ‘Quick Access’ list. This feature allows the user to pin their favorite folders to the top of the list for quick, one-click access.

Recently used folders show up below the pinned items in the list, which can be handy when the user is working with a group of files.

To add a folder to this list, right-click it and select Pin to Quick Access. To remove a folder from the list, right-click the folder and select Unpin to Quick Access.




Frequent folders section

When the user first opens the File Explorer, any items in the Quick Access list also show up in the Frequent folders section. Recently used folders show up automatically in this section.

Software: Microsoft Snip

Microsoft has just released a new and very handy screen capture application, it's called Microsoft Snip. The app allows you to capture any window or area of your screen.

You can then annotate it with narrated comments or draw on it with digital ink. You can then copy and paste it into another application, or share it with your friends and colleagues by sending a URL to it, or save it as an MP4 video.
