Windows 8 display lock screen timeout setting.
I needed to blog about this as this is a setting that should be exposed without registry settings, but for now that is all we have.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7
Change the Attributes value to “2” vs. “1”
