How to turn off McAfee programmatically

You should not be generating new labels by writing code that creates the controls.

You should be using the .Add method on the Controls collection to create new labels.

For example:

UserForm1.Controls.Add("Forms.Label.1", "foo", True)

You can use WithEvents to get the events.

For example, in UserForm1,

Public WithEvents a As MSForms.Label

Private Sub a_Click()

    MsgBox "label clicked"

End Sub

Private Sub CommandButton1_Click()

    Set a = UserForm1.Controls.Add("Forms.Label.1", "foo", True)
    a.Visible = True
    a.Caption = "Hi There"

End Sub

If you want to make a dynamic array of newly added controls, you'll need to create a little wrapper class. Sample code for that is here.

Probably too late :) , but hopefully useful for others.

The following steps worked just fine for me (it worked on W8 consumer preview too).

to turn it off:

1 - Enable guest account by running

net user guest /active:yes

2 - Obtain guest user SID by running, for example,

wmic useraccount where name='guest' get sid

3 - Obtain write access to registry folder HKLM\SECURITY

4 - Modify the following key, where $SID is the sid obtained in point 2, to:

[HKEY_LOCAL_MACHINE\SECURITY\Policy\Accounts\$SID\ActSysAc]
@=hex(0):41,00,00,00

5 - restart the machine (until now, I didn't find a better way to make the change effective)

to turn it on again:

[HKEY_LOCAL_MACHINE\SECURITY\Policy\Accounts\$SID\ActSysAc]
@=hex(0):c1,00,00,00

then restart
