Question: There is already a similar [question](https://superuser.com/questions/442565/is-it-possible-to-filter-addresses-in-the-cc-field-but-not-in-the-to-field), but it doesn't work for me because I'm not a direct recipient (I'm member of a group).

I'm trying to set up a new rule for incoming messages.
Suppose we have

```
# GroupA
# GroupB

```

and a message arrives

```
TO: # GroupA
CC: # GroupB

```

I have a rule set up, which is saying:

> 
> Apply this rule after the message arrives   
> 
>  where sent to **# GroupB**   
> 
>  move it to the **ToGroupB** folder   
> 
> 
> 
> 

But this detects **# GroupB** as a recipient, so it moves the message to the **ToGroupB** folder, which is not what I want.
Can I have a rule which works only based on TO field?

Answer: 
If you know the *password* of the Administrator account, you can run regedit as an administrator, either by doing a search for "regedit" in the start menu and then right-click and do "Run As Administrator"; or by starting a command shell as administrator and run `regedit` in there, or by using [runas](http://ss64.com/nt/runas.html).

All methods require knowledge of the Administrator password.

If you get really stuck, you can boot a Linux live CD that lets you install packages -- e.g. Ubuntu -- and use `chntpw` to set the Administrator password, then you can perform the method as above. See [here](http://lifehacker.com/5584762/edit-the-windows-registry-from-a-linux-thumb-drive) for an okay article (it's not very well-written) with details on that.
* `Win+R` -> `cmd` -> `runas /user:COMPUTER_NAME\ADMIN_ACCOUNT cmd`
* Enter password.
* In the elevated window open: `regedit`
* Edit the key.
