Question: I am running Windows 7 64 bit Ultimate and using Cisco AnyConnect VPN 2.5.3041. As expected, Fast User Switching got disabled as soon as I installed the VPN software.

This [FAQ](http://www.cisco.com/en/US/products/sw/secursw/ps2308/products_qanda_item09186a00801c2dbe.shtml) from Cisco references how to enable Fast User Switching when their VPN product is installed:

> 
> A. Microsoft automatically disables Fast User Switching in Windows XP
>  when a GINA.dll is specified in the registry. The Cisco VPN Client
>  installs the CSgina.dll to implement the "Start Before Login" feature.
>  If you need Fast User Switching, then disable the "Start Before Login"
>  feature. Registered users can get more information in Cisco Bug ID
>  CSCdu24073 (registered customers only) in Bug Toolkit.

My problem is that I have disabled this on the client, but fast user switching is still greyed out.

This [article](http://windowsxp.mvps.org/ginadll.htm) mentions a registry edit, however they key they mention, GinaDLL, does not exist at the WinLogon registry point.

**Update:**

This [article](http://www.cisco.com/en/US/docs/security/vpn_client/anyconnect/anyconnect25/administration/guide/ac03features.html) from Cisco covering AnyConnect specifically gives a one liner:

```
AnyConnect is not compatible with fast user switching.

```

The only problem is I now I had found a workaround before the last reformat/reinstall, but I can't remember what exactly I did previously.

Answer: 
Note how that FAQ mentions, with emphasis mine:

> 
> Microsoft automatically disables Fast User Switching **in Windows XP** when a GINA.dll is specified in the registry.
> 
> 
> 

Which is why you have came to the suggestion:

> 
> This article mentions a registry edit, however they key they mention, GinaDLL, does not exist at the WinLogon registry point.
> 
> 
> 

Luckily you are smart enough to not just simply create that entry, because let's see what Microsoft has to say about GINA, [deep in the development center](http://msdn.microsoft.com/en-us/library/windows/desktop/aa380543(v=vs.85).aspx) we find:

> 
> **Note:** GINA DLLs are ignored in Windows Vista.
> 
>

Exactly, GINA is longer supported since Windows Vista. So, not the right way to go about this...

Now, if that software can disable Fast User Switching, we can do the opposite:

1. Start the Group Policy Editor (Start -> Run ->`gpedit.msc`).
2. Go to Computer Configuration -> Administrative Templates -> System -> Logon.
3. Set “Hide entry points for fast user switching” to “Not Configured” or “Disabled”.
4. Do a `gpupdate /force` to update the registry, add `/boot` if you wish to reboot and reload it.

If you don't have the group policy editor, you can:

1. Launch a registry editor (Start -> Run -> `regedit.exe`)
2. Go to `HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\`
3. Delete `HideFastUserSwitching`.
4. Optionally, reboot your system to reload the settings.
After "unhiding Fast user switching" on windows 10 Pro (Many links on a search gives the solution on how to do it on Winws Seven or Vista), I had to run Services.msc and disable network Access Management Logon Module.

Though, disbling this service will make some NAM's functions unavailable.

Fast User switching works fine now.
