I need some explanation about how Registry Filter works.
According to MSDN, it only works with two special keys. TSCAL and Domain
secret keys. It says it "supports persisting specific registry changes across
reboots without requiring all registry changes in a file to be persisted. "
Can anyone tell me how these two keys work? Do they need change
occasionally, and Registry Filter allow them to be, or as if to be, "written
through", like FBWF, even though the system drive is protected by EWF.
I found the article by Cuong "Registry Filter Tips" from the XPE team blog
talked about the possibility of applying RF to other registry keys, which
raise my hope of using it in our product. It talked about setting three items
- ClassKey, RelativeKeyName and FileNameForSaving . Because of the lack of
understanding how RF works, I don't get what the FileNameForSaving is for.
Should I provide a reg file for the registry key that I want to protect when
I build the run-time image? Where should I put it? Should I put it on a
unprotected volume? Why the file name in his example does not have an
absolute path, but just "MyFile.reg"?
I know some people use this feature to save time zone information. Could any
one give me some advice on it? Or at least verify me that my understanding of
"Registry Filter" as a filter to set some "holes" in the registry, like
FBWF, is correct or not.
Looking forward for your replies.
Thanks.
