How to uninstall the “Microsoft Advertising SDK” Visual Studio extension?

Run the following from an elevated Powershell prompt:

gwmi Win32_Product -Filter "Name LIKE 'Microsoft Advertising%'"

And it should show the culprits:

IdentifyingNumber : {6AB13C21-C3EC-46E1-8009-6FD5EBEE515B}
Name              : Microsoft Advertising SDK for Windows 8.1 - ENU
Vendor            : Microsoft Corporation
Version           : 8.1.30809.0
Caption           : Microsoft Advertising SDK for Windows 8.1 - ENU

IdentifyingNumber : {6AC81125-8485-463D-9352-3F35A2508C11}
Name              : Microsoft Advertising SDK for Windows Phone 8.1 XAML - ENU
Vendor            : Microsoft Corporation
Version           : 8.1.40427.0
Caption           : Microsoft Advertising SDK for Windows Phone 8.1 XAML - ENU

IdentifyingNumber : {5C87A4DB-31C7-465E-9356-71B485B69EC8}
Name              : Microsoft Advertising SDK for Windows Phone - ENU
Vendor            : Microsoft Corporation
Version           : 6.2.960.0
Caption           : Microsoft Advertising SDK for Windows Phone - ENU

IdentifyingNumber : {EBD9DB6D-180B-4C59-9622-B75CC4B32C94}
Name              : Microsoft Advertising Service Extension for Visual Studio
Vendor            : Microsoft Corporation
Version           : 12.0.40402.0
Caption           : Microsoft Advertising Service Extension for Visual Studio

Then to actually uninstall add | foreach { $_.Uninstall() } to the command like so:

gwmi Win32_Product -Filter "Name LIKE 'Microsoft Advertising%'" | foreach { $_.Uninstall() }

Which should display for each one:

__GENUS          : 2
__CLASS          : __PARAMETERS
__SUPERCLASS     : 
__DYNASTY        : __PARAMETERS
__RELPATH        : 
__PROPERTY_COUNT : 1
__DERIVATION     : {}
__SERVER         : 
__NAMESPACE      : 
__PATH           : 
ReturnValue      : 0
PSComputerName   : 

The important thing to look for is ReturnValue : 0 which means success. If you get ReturnValue : 1603 it likely means your Powershell prompt wasn’t elevated (running as admin). (Full list of ReturnValues documented here)
