Wine and damage of original MS Windows

[Petr Mladek]

Hello,

I want to protect original MS Windows installed on their partition
against wine :)

I have not own experiences with similar problems but I fount next 
message in README:

----
You should backup all your important files that you give Wine access
to, or use a special Wine copy of them, as there have been some cases
of users reporting file corruption. Do NOT run Explorer, for instance,
if you don't have a proper backup, as it renames/cripples several
directories sometimes. Not even other MS apps such as e.g. Messenger are safe,
as they launch Explorer somehow. This particular corruption (!$!$!$!$.pfr)
can at least partially be fixed by using

Do you have any idea how to protect original Windows without backup?
Or is the backup the only solution in this time?


Thanks for hints,

Petr
