Cursor blink rate always stays on FAST

I am running into this weird issue with blinking cursor rate.  This is Windows 7 VMs.

I set the following on the gold image.

We set blinking cursor rate (Control Panel > Keyboard) down to third line from the left.  Save the setting.

Also updated following registry key.

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Control Panel\Desktop]

"CursorBlinkRate"="0xffffffff"

"DisableCursorBlink"=dword:00000001

The setting works in gold image but once recomposed VMs does not.  Blinking cursor rate is always set to FAST even if you update it on the VM.

Anybody out there ran into this issue...
