Hey,

one software needs write permisson in HKEY_LOCAL_MACHINE\HARDWARE but when we change it and then reboot Vista, the permission disappeared :(
So after every reboot Vista (and also 7) resets the permisson.

Is there any way how we can change it for longer term as one system uptime?

Thx
Stephan

Vista uses different branch names for 32-bit and 64-bit apps, doesn't it?

That would be standard windows internal self repair, like the current xp unsigned driver dialogs which self repair when changed. What is it your trying to do with that key and why do you need to open it?

As far as I know a user with Administrator rights can only modify the HKLM\Hardware hive. Normal Users cannot modify it. Permissions cannot be set on this hive because the information it stores is dynamic. The operating system creates this key each time it boots and stores the hardware information that it detects on booting. This can be the reason why the permissions set by you disappears on reboot.
