I have trouble running software with a limited user account. For example, common software such as disc burning, camera software, a label creator, etc, require an admin account to function, but I cannot surf nor let my kids indiscriminately install programs. Roxio support told me their software requires a user account with admin priveleges. I found that I can run Roxio etc under a limited account if I manually adding user priveleges to the registry entries. You seem to understand the registry and could fix this common problem easier then I did by hand. I fixed it by searching the registry for Roxio and adding user permissions to those keys. For other software, I took a snapshot of the registry before and after installation to identify the registry keys to add permissions. Some software added hundreds of registry entries. I'd accept a license if you think this is a good idea for a new product feature. Thanks.
