SAFER security levels
Reading Michael Howards blog, I saw an article about safer browsing using software restriction policies.
Browsing the Web and Reading E-mail Safely as an Administrator, Part 2
He mentions there are 3 security levels that are not normally displayed in the Group Policy Editor
Unfortunately he only tells us the value to get Basic User to display, so I have added the others below.
Values
0x10000 - Constrained (also named Restricted)
0x20000 - Normal User (also named Basic User)
0x01000 - Untrusted
0x31000 - to get all 3
Copy the text below to make a reg file
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers]
"Levels"=dword:00031000
