A common problem is that some people using Windows 8 cannot find Local Security Policy Editor. In fact, Gpedit in Windows 7 has been changed into Secpol in Windows 8. Secpol controls the security subset of local group policies.
Now I will show you how to launch the local security policy to change your security setting.
1. Click on the Start orb, and in the search dialog box type: secpol.msc
Note: Remember to type the .msc file extension, otherwise Windows 8 can't find the snap-in.
2. When secpol.msc appears in the search results, consider creating a shortcut by right-clicking and choosing either 'Pin to Taskbar', or 'Pin to Start Menu'.
3. Navigating through the security settings is as easy as finding files and folders with Windows Explorer.
If you have Active Directory then you don't need Secpol because you can use the GPMC (Group Policy Management Console) on the domain controller. However, if you are checking or configuring security settings on a Windows 8 computer in a Workgroup or HomeGroup then you need the Local Security Editor - secpol.msc.
