Unable to RDP to windows 7 (Lenovo) machine

My company recently purchased few Lenovo laptops and desktops. They came in with Windows 7 OEM install image. I was not able to RDP into few of those machines and further research led me to the below missing registry key.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

and the value for Security Packages should be


kerberos
msv1_0
schannel
wdigest
tspkg
pku2u

if you have similar issue just copy the above and update the field.
