I am using 
 Windows 7 Professional 32 Bit and my windows is activated. Since i have installed 
 Windows 7 Professional i have never enabled 
 Windows 7 Starter Serial as i am unsure that it may deactivate my 
 Windows 7 Pro 32 Bit or may hamper working of my non genuine 
 Windows 7 Enterprise Serial. So i want to know if it will be safe to enable windows updates?
