Unable to enter backslash at Windows logon screen (but once logged on it works)

Hello,

I am unable to enter the backslash character at the Windows logon screen. Tried using both Swedish (SV) keyboard and English keyboard but can't get a backslash. Instead of backslash I get another character (±, the same character as I get in OSX when entering the Windows backslash keys Alt + "+"). Seems like the parallel tools are not fully active in the Windows logon screen. Tried all variants of shift, control, alt and all keyboard keys. Also tried connecting an external USB Windows keyboard but same result.

Once logged into Windows I have no issues to enter backslash.

However I need to enter backslash at the logon screen in order to logon to another domain (i.e. enter "domain\user").

Would be good if the backslash (or even better a full character palette) was possible to enter via the menu Devices / Keyboard (where there are some keyboard combinations like Control-Alt-Delete) since in my experience backslash is often a problem when it comes to keyboard mapping and in such cases a quick workaround may be desired to sort out an urgent issue.

Anyone have any ideas?

Host:
OSX 10.8.4
MacBook Pro 15 mid 2010
Parallels Desktop version 8.0.18608

Guest:
Windows 7 64bit SP1
Parallels tools are installed

 

Found a workaround!

I can enter backslash by entering "RIGHT-alt, Shift and 7". Previously I had only tried with LEFT-alt, didn't realize there was a difference.

Still I am looking for a fix, so that the ordinary keyboard setting are applied also at the logon screen.
