RE: Registry corruption by device driver

[Steven Liu [MSFT]]

Hi Naomi,

The registry file is protected by the OS. We can't change the file from the
network computer by the network driver.

We can change the remote computer's registry by running the regedit and
select the remote computer in the File > Connect Network Registry.

Thanks for using Microsoft News Group!

Sincerely,

Steven Liu

| Hi,
|
| Is it possible for a network device driver to do a stray write which will
| corrupt the registry file for the next boot, or is that area of the RAM
| protected?
|
| (I am developing a network driver for Embedded XP and the registry file
| seems to get corrupted - after proper shutdown the system failed to load
and
| indicated either SYSTEM or SOFTWARE are corrupted. Our storage is a
Compact
| Flash. This error can be reproduced by restarting the system over and
| over.).
|
| Many thanks,

You can for example write a simple VB program to access and change any
settings in the registry. Your driver could do the same.

Hi Naomi and John,

I believe we are not talking about Windows XP for PC but the Embedded XP.

The registry access mode should be different on the special storage device.

I suggestion you may post this to microsoft.public.windowsxp.embedded
