Starting with Windows Vista to this operating system appeared User Account Control, which when enabled, prevents writing to the HKLM branch of the registry, even applications running on administrator. Our app kept General settings (independent of users) HKLM\\Software\\OurCompany\\OurProduct\\Settings. Now there can not write. Writing to HKCU does not want a generic settings common to all users.
Question: so where it to write? Somewhere there is a section available to read and write for all users? (Please do not offer to write to the file — there are reasons).
