Security policy won't let me log in, HELP!!

Thank you for this, however, I am able to logon as the Administrator in safe
mode, I just can't remember what I changed to prohibit logging in normaly.
I have checked the registry C:\Windows\System32\Userinit.exe, and it all looks fine.
THe problem is a security setting that will not allow windows to launch this
file.
In the Event Viewer I see the following log:
Access to C|WINDOWS\system32\userinit.exe has been restricted with policy {191cd7fa-f240-4a17-8986-94d480a6c8ca}

Looking in 'Local Security Policy' all looks OK here with no restrictions. N
one-the-less, I find Policy {191cd7fa-f240-4a17-8986-94d480a6c8ca} in the 'E
vent Viewer' as set by the administrator (me) won't allow userinint.exe to r
un.

I can also find this policy in the registry, do you think I should simply del
ete the policy folder?

I find this folder in the registry by running regedit in the command line th
en my computer > HKEY_LOCAL_MACHINE > software > policies > Windows > safer
> code identifiers > paths > {191cd7fa-f240-4a17-8986-94d480a6c8ca}.
When I open this folder I see the following:

Name Type Data
(default) REG_SZ (value not set)
Descritpion REG_SZ
ItemData REG_Z EXPAND_SZ
%key_local_machine\software\microsoft\Wind..
SaferFlags REG_DWORD 0x000000000(0)

Should I delete this whole thing of change a value somewhere?
