Hello,

I need to know how to access the registry from a DOS or start-up screen as I've to remove a memory resident virus and I don't have a bootable floopy to boot from or any way to go online to download any type of software or utility to install on my system (I'm using this computer for a limited time and can't use it for downloading stuff) - I've been told that it is possible. Does any of you know how to do it?

Any help would be greatly appreciated,
Thanks.

What do you want to accomplish?

Can you provide more detail as to the problem?

A 9x machine does not provide any tools to do this in raw DOS. A third party tool capable of working with database files must be used.

If you have a virus there are floppy based virus removal tools available.

I strongly suggest that you understand the ramifications of accessing the registry in DOS (outside of the windows GUI/RegEdit utility), AND, ensuring the integrity of any registry entry files you wish to import.

To add a registry entry in dos; (filename.reg)

Imports and exports registry files to and from the registry.

REGEDIT [/L:system] [/R:user] filename1
REGEDIT [/L:system] [/R:user] /C filename2
REGEDIT [/L:system] [/R:user] /E filename3 [regpath1]
REGEDIT [/L:system] [/R:user] /D regpath2

/L:system Specifies the location of the SYSTEM.DAT file.
/R:user Specifies the location of the USER.DAT file.
filename1 Specifies the file(s) to import into the registry.
/C filename2 Specifies the file to create the registry from.
/E filename3 Specifies the file to export the registry to.
regpath1 Specifies the starting registry key to export from.
(Defaults to exporting the entire registry).
/D regpath2 Specifies the registry key to delete.
