Hide Local Disk (Q:) added by Office 2010 Beta

Those who have read my previous post on Office 2010’s “Click-To-Run” feature would understand why Local Disk (Q:) was added to the system. While it is an important part of Office 2010 Beta’s “Click-To-Run” feature, it can get quite irritating when you accidentally click it while browsing through the system.

Here’s how to hide it.

Firstly, bring up the registry editor by clicking Start > Run or pressing “Windows Key+R” then enter “regedit” without the quotes and click “OK”.

Next, browse to the following registry key:

HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Add the DWORD Value

Add the following registry key by clicking Edit > New > DWORD (32-bit) Value:

Value Name: NoDrives

Value Data (Decimal): 65536

DWORD Value added

Once this value has been created, click OK and close the registry editor.

Please note that this fix will only work in the user account you’re currently logged into.

To apply this fix machine-wide, make changes to the following registry key:

HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Alternatively, you can also create Binary values as described in Microsoft’s KB555438.

There you go. This should put an end to the “Access is denied” error message while maintaining Office 2010 Beta’s “Click-To-Run” functionality.

All the best!

    after trying out the above step and rebooting the machine, now we are not able to
    see C drive.it seems hidded.Please let me know how to make C drive appearing.

    • reverse the steps you performed.

    • change the value to 0 and then click the radio button decimal and type 65536 then right click your taskbar and click task manager and go to the prosess’s tab ad end explorer.exe then go to the applications tab and click new task and put in explorer then hit enter and go to computer/my computer and you wil see your drives back as well as local disk Q: is gone!!

        мне удалось удалить этот диск Q достаточно просто – задал в поиске по реестру значение Q: и аккуратненько удалил все записи, касающиеся этого диска… потому что там были и другие, содержание Q:, но не относящиеся к этому диску. После перезагрузки этот диск отовсюду исчез.

    i’ve tried the same thing, and mine went hiding, but then i fixed it by deleting the reg file and restarting explorer. (both drives are there now) i think that happened because my version in not beta. how would i get v.14 (latest) to hide the drive?

  4. thnks…! dat was nice nd easyy! :)

    When I go into the registry, the last part of the path you mentioned doesn’t exist… for me it’s:

    HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\

    and after that is: Attachments, NonEnum, and System. None of them contain Explorer.

    Would I be able to get to the right place by doing HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\ instead, or can I not bypass Policies? It’s almost the same when I try it for HKCU, but there’s nothing inside Policies except the one item (of binary data, I guess?) Thanks for your help!

    Maybe I should’ve mentioned that it’s just Microsoft Office 2010 that I’m using, not the BETA version. I don’t know if that makes a difference.

    Windows 7 uninstall failed and microsoft knowledge base states basically you cannot remove this.
    To get rid of just Q :
    run

    regedit

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2

    under this tree I found a value of “Q”
    Deleted It
    Rebooted and Q is no longer displayed on my COMPUTER
    going back to office 2k3

  8. I only found HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\ wthout Explore.What is the problem?? Thanks you

    I changed the key but Q disk’s still there…!

  11. Sisir Vamsi

    figured it out…:)
    this trick will not work if the disk is renamed..

    HKCU is wrong. It has to be HKLM (HKEY_LOCAL_MACHINE)!
