Duplicate OneDrive Icon in File Explorer

 I just got a new laptop and after doing most of the configuration I noticed that there were two OneDrive folders in File Explorer. The top one is named for my work tenant and the lower just named OneDrive. Typically the icon named OneDrive is for the personal version of OneDrive but I didn't have that configured. Only a OneDrive for Business account was configured.

When I clicked on the OneDrive icon it opened the same content as my OneDrive for Business. So, it appeared to redirect.

In my user profile folder (C:\Users\ByronWright\), I saw that there was a folder named OneDrive. When I deleted that folder, the redirection stopped and I got an error indicating that the folder didn't exist. Whoops. No fix there.

After a bit of searching around I found that I could remove it by removing the reference to it in the registry. That area of File Explorer is controlled by HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace. In that registry key, I had two registry keys that looked like GUIDs. Inside I could see one with the name OneDrive and the other was the OneDrive for Business name.

I deleted the registry key that referred to OneDrive (the entire key named like the GUID) and it immediately removed the extra reference to OneDrive from File Explorer.

My new laptop was originally purchased with Windows 11 Home edition which required me to sign in with a Microsoft account during setup. This configured personal OneDrive at the time. I upgraded the laptop to Windows 11 Pro and did a system reset but I think the reference to personal OneDrive was left over in the default user profile which was then copied when I signed in as my Azure AD (Entra ID) user.

Immutable ID, ms-ds-consistencyGUID, and object GUID conversions

It seems like I'm constantly need to convert immutable IDs and GUIDs as part of my M365 migrations. To simplify this I finally got around to writing some functions that simplify the work instead of looking them up all the time.

I created the following:

  • Convert-ImmutableIDToGUID
  • Convert-ImmutableIDtoHexString
  • Convert-ImmutableIDtoByteArray
  • Convert-ByteArrayToGUID
  • Convert-GUIDToImmutableID
  • Convert-HexStringToGUID
  • Convert-HexStringToImmutableID
  • Convert-ByteArrayToImmutableID

To make these available at a powershell prompt, you can load them as part of your powershell profile or dot source a script that contains.

Example of dot sourcing:

. c:\scripts\convertfunctions.ps1

Code for the functions:

# Example immutable ID to play with
# $ImmutableID = "GJo33fsMIUKvmIIyTOSjzg=="

function Convert-ImmutableIDToGUID {
    param ($ImmutableID)
    return $guid

function Convert-ImmutableIDtoHexString {
    param ($ImmutableID)
    $hexstring=([Convert]::FromBase64String($ImmutableID) | ForEach-Object ToString X2) -join ' '
    return $hexstring

function Convert-ImmutableIDtoByteArray {
    param ($ImmutableID)
    return $bytearray

#When you retrieve ms-ds-consistencyGUID from AD it is a byte array
#to avoid this conversion use [guid]$user.'ms-ds-consistencyGUID'
function Convert-ByteArrayToGUID {
    param ($bytearray)
    return $guid

#works with GUID object or string in GUID format
function Convert-GUIDToImmutableID {
    param ($guid)
    $immutableID = [system.convert]::ToBase64String(([GUID]$guid).ToByteArray())
    return $immutableID

function Convert-HexStringToGUID {
    param ($hexstring)
    $guid = [GUID]([byte[]] (-split (($hexstring -replace " ", "") -replace '..', '0x$& ')))
    return $guid

function Convert-HexStringToImmutableID {
    param ($hexstring)
    $ImmutableID = [system.convert]::ToBase64String([byte[]] (-split (($hexstring -replace " ", "") -replace '..', '0x$& ')))
    return $ImmutableID

function Convert-ByteArrayToImmutableID {
    param ($bytearray)
    $ImmutableID = [system.convert]::ToBase64String($bytearray)
    return $ImmutableID

<# Use Example

$msdsconsistencyGUID = (Get-ADUser Byron -properties *).ms-ds-consistencyGUID
$ImmutableID = Convert-ByteArrayToImmutableID -bytearray $msdsconsistencyGUID
Set-AzureADUser -ImmutableID $ImmutableID
