Quickly find uninstall GUID of product in Programs and Features

Ever get tired of digging through the registry HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall and HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall keys searching for a product?  Luckily, there's a much faster way to find the GUID, simply run the following command--in this case, we are searching for the Symantec uninstall string:

wmic /node: product get | findstr Symantec

Though the formatting of the result is off, it's still quite easy to locate the GUID and proceed to uninstall the product like so:

msiexec /x {guid}

Skype for Business / Lync 2013 Outlook Properties Dialog Implementation

Since the advent of Office 2013, I've been increasingly frustrated with the new Outlook contact cards, and the round-about way needed to access the legacy GAL properties dialog as shown below:

After a ton of research, I discovered it's possible to add custom context menus within the Lync 2013 / Skype for Business client, as per this page from Microsoft.  From here, I needed to discover the API necessary to actually launch the legacy GAL properties dialog box.  Doing a bit of research, I simply could not find an easy way to do this, the only thing I was coming across was the following registry key, which just launched the GAL properties box from within Outlook:

DWORD: TurnOnLegacyGALDialog
Value: 1 (enable)

Nearly giving up after hours of digging through the API and searching, I was provided some help via Dmitry Streblechenko on StackOverflow (thank you, Dmitry!).

In the end, I ended up with a simple VBS and registry key:

If WScript.Arguments.Count = 2 Then
                Dim objOutlook : Set objOutlook = CreateObject("Outlook.Application")
                Dim objNamespace : Set objNamespace = objOutlook.GetNamespace("MAPI")
                Set objOutlook = Nothing
                Set objNamespace = Nothing
End If

Windows Registry Editor Version 5.00

"Name"="Outlook Properties"
"Path"="C:\\\\windows\\\\System32\\\\wscript.exe C:\\\\temp\\\\LaunchGALProp\\\\LaunchGALProperties.vbs \"%user-id%\" \"%contact-id%\""
Boom!  After restarting Skype for Business, I was treated with the following view:

It's quite unfortunate that Microsoft removed this functionality within the newer versions of the Lync/Skype clients, but at least with a little bit of elbow grease I was able to recover it...for now.

Find All Servers in OU Utilizing dsquery

Recently at work I needed to pull all servers from a specific OU and Get-ADComputer was not working for some reason.  I didn't feel like taking the time to figure it out so I just reverted back to handy dsquery:

dsquery * OU=Test,DC=contoso,DC=local -scope subtree -limit 999999999 -filter "(&(objectClass=Computer)(objectCategory=Computer))" -attr sAMAccountName operatingSystem

JavaScript Convert String to Bytes Function

Just wanted to post a quick JavaScript convert string to bytes function just for myself, but I figured someone else may find it useful:

function convertToBytes(str) {
     var bytes = [];
     for(var i = 0; i < str.length; ++i) {
          var charCode = str.charCodeAt(i);
          bytes = bytes.concat([charCode & 0xff, charCode / 256 >>>             0]);

     return bytes;

And my slightly improved, ES6 compatible version:

function convertToBytes(str) {
     var bytes = [];
     Array.from(str).forEach((char) => {
          var charCode = char.charCodeAt(char);
          bytes = bytes.concat([charCode & 0xff, charCode / 256 >>>             0]);

     return bytes;

That funky bytes concatenation line simply enables the function to work with Unicode characters.
