Opening Explorer shell with admin privileges on XP (with IE7 installed)

Question

I used to demote my user account so that it had no admin priveleges and used a 'sudo-like' trick where you create a shortcut to IE6 and enabled the 'Run with different credentials' option to open a shell window as local admin so I could install and uninstall things, etc.

When I upgraded to IE7 this stopped working - IE7 launches Windows Explorer separately.

I've tried running Windows Explorer with different credentials but this does not work.

Does anyone know how to re-enable this behaviour so that I don't have to run my computer on a daily basis with administrator privileges?

Solution 1

I always use the following command to launch a separate explorer shell on XP/IE7. Looks like /separate switch is undocumented (haven't seen it much on the web till recently).

Use this syntax in "Target" of an Explorer.exe shortcut:

runas /user:ComputerName\AdminName "C:\WINDOWS\explorer.exe /separate"

• Replace ComputerName with yours (may be your Domain), ditto AdminName. Remember, all this above goes in the "Target" field of a Shortcut to C:\Windows\explorer.exe
• Enter the Admin password in the Pop-up Command Prompt and you should see the separate explorer shell (running under the administrator account)

If you change the Toolbar Background of Explorer while logged in as the Admin using gpedit.msc (for XP Pro), when you start a RunAs Admin Explorer instance from the User session, you will see the unique background... and KNOW you're running Admin Explorer (instructions here).

My example tested on XP x64 with IE7 works great:

In Windows XP, you can run Windows Explorer as any other user, including "Administrator", by following the "Option 2" instructions on Aaron Margosis's blog post entitled RunAs with Explorer: http://blogs.msdn.com/aaron_margosis/archive/2004/07/07/175488.aspx.

In short:

1. Log onto the machine as the user that you eventually want to RunAs.
2. Navigate to the Folder Options control panel, and check the option "Launch folder windows in a separate process".

I use this all the time, and so I have included the following *.cmd script in my new machine build process:

rem Tested on Windows XP only!
reg load "HKU\TempDefaultProfileHive" "%ALLUSERSPROFILE%\..\Default User\ntuser.dat"
reg add "HKU\TempDefaultProfileHive\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "SeparateProcess" /t REG_DWORD /d 1 /f
reg unload "HKU\TempDefaultProfileHive"

This script turns on the "Launch folder windows in a separate process" setting for all new profiles that are created based on the machine's default user profile.

All the pieces to the puzzle have been posted, but they just need to be put together.

To run Windows Explorer as Administrator under a non-Administrator account, you have to:

1. log into the computer as the Administrator
2. open Windows Explorer
3. goto the Tools menu and select Folder Options...
4. goto the View tab and check Launch folder windows in a separate process

If you log into the computer as a non-Administrator, running

runas /user:administrator explorer.exe

will now work. This can probably be set via the registry, but I think this is the easiest way.

Solution 4

You can use runas.exe to run a program (for instance a windows console) under different credentials. I have a shortcut on my desktop called 'su' that links to this:

%windir%\system32\runas.exe /noprofile /user:administrator cmd

This will start a console box asking for the administrator password.

@Huppie - runas is great, but launching explorer doesn't seem to work. I can run cmd just fine, or my AD console, but explorer just fails without throwing any sort of error.

Windows Explorer is (sadly) a bit too integrated with windows, it cannot be opened with runas... try using a different file browser (for instance Total Commander).

Gulzar has an (undocumented) solution to run explorer with runas:

%windir%\system32\runas.exe /user:administrator "explorer.exe /separate"

Solution 5

If your question relates to your own computer, I cannot recommend SudoWin enough: it allows you to perform the "sudo" trick (supposedly a well-known Linux/Unix command) under Windows. In other words: it lets you run programs under your own account, but with admin privileges. This means that programs retain the preferences and settings they would have if they would run under your account (registry, user profile), but then with admin privileges, protected by the password of your own account. It's a feature you can't live without once you've got to know it, and the implementation is great!

[EDIT] And did I mention it's completely free (open source)?

@Huppie try /separate switch as mentioned in my post

This is what I used to do with IE6 although it does not work any longer with IE7 - IE7 is launched but Explorer windows spawned do not have the right credentials. If you do this with Windows Explorer it just does not work.

Would be really great to have a way of knowing the owner of an explorer window (at the title bar, status bar or something like that). Do you know if this is possible?
