I've been looking at a couple of customer machines and trying to figure out why registry changes aren't being persisted when the machine is powercycled (powerloss etc).
These machines aren't on a domain and they are setup with just basic automatic logon of a user.
(all the below performed as a local administrator)
If you go in with Regedit and make a change on the machine exit and then come back it's all ok.
If you go in with Regedit and make a change then restart the machine the change is there when you come back.
If you make a change with Regedit, Exit regedit and reopen to check it's still there, but if the machine then losses power the registry change is lost.
Is there something I can look at see why these changes are not being stored to the registry?
I know that some of the machines are XPsp2, and XPsp3. I can't exactly pin as to why it is being lost. (And yes I have asked the customer to Update their machines to sp3 and patches etc).
