Windows – How to remove the Dropbox entry from the Windows Explorer navigation pane

dropboxwindows 10windows-explorer

To start, I have already uninstalled Dropbox from my system. However, as the title suggests, the navigation pane entry resides, rather annoyingly, and seems to be the cause for a slowdown in Windows Explorer's performance.

If I click the entry I get the standard resource unavailable message.

I have already searched for the issue and followed guides posted on the dropbox forum and on reddit and tried this .Bat program (thanks to @Yisroel Tech). None helped me solve the issue as the Registry Keys that they mention {E31EA727-12ED-4702-820C-4B6445F28E1A} don't exist anymore (I assume, because its no longer installed).

I have also restarted the PC and separately, Windows Explorer, in my efforts.

Any other ways to remove the item from the Navigation Pane?

EDIT:

There aren't any options in the right click menu to remove the item.

I've now tried to add the key {E31EA727-12ED-4702-820C-4B6445F28E1A} with a REG_DWORD of System.IsPinnedToNameSpaceTree and value of 0 to the locations
HKCR\CLSID\, HKCU\Software\Classes\CLSID\ and HKCU\Software\Classes\WOW6432Node\CLSID\ to no effect.

I also tried searching the location HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\ for something relating to Dropbox but there isn't anything.

Result:

After using the answers below to find keys I came across a set of four keys labeled dropbox under HKEY_USERS\S-1-5-21-600964879-747821205-3265537649-1932 all of them ending in {E31EA727-12ED-4702-820C-4B6445F28E1A}, so I'm not sure why they didnt turn up in my original searches but they were there.

One option is to go through the registry but not the way you did it. It should be done by changing the existing key, not by adding a new one. I had cases where the "CLSID"-Number didn't match (maybe due to the windows/Dropbox version, but I'm not 100% sure about it). If this is the case for you, try to find the right key/value first:

  • In the registry try to locate System.IsPinnedToNamespaceTree (search for values, not keys or data => see note at the bottom of my answer).

    enter image description here

    Make sure you start searching at the "root folder" (Computer).

    enter image description here

  • You should find a registry key/value that looks like this:

    HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID{E31EA727-12ED-4702-820C-4B6445F28E1A}\System.IsPinnedToNamespaceTree

    enter image description here

    Depending on the software you have installed there will be somewhat around 20 or more in total. Make sure you got the one that belongs to Dropbox. Usually there should be some kind of "dropbox-reference" in the registry key. If you are unsure you can search for the CLSID on the internet, it's a unique global identifier.

  • Change the data of the System.IsPinnedToNamespaceTree-value to 0

    enter image description here

Make sure you don't just change the one you created yourself. There should already be one that has been created by the Dropbox installer. And make sure to change all the created keys for Dropbox (with the same CLSID-Number) not just the first one you find. You should find a second one within the key HKEY_CURRENT_USER\SOFTWARE\Classes\Wow6432Node\

If Dropbox has been deinstalled the "data" should remain 0. There might be some process of Dropbox that still gets executed at startup and changes it back to 1. In this case you can remove access altogether to the CLSID-key (right click, choose permissions and select "access denied").

Note: In the registry....

  • the "folders" are called keys
  • the "entries" in the folders are called values
  • the "values assigned to the entries" are called data
