Log On to XP entering characters using Unicode

[Pelikal]

Okay, I have an old XP laptop, it's sole purpose is to control my Microtek scanner. I use a win7 machine to connect to the Internet, just wanted to make that clear.

I log on to this XP Toshiba as administrator with a password (I am the only user).

Now, one of the keys on the laptop no longer works (cap R) so I can't log on to the machine at all. My first thought was to try and change the password as I have in the past 'got into' an XP machine and changed the password but I can't remember how I did it and have lost my notes.

I've tried a number of suggestions by doing a search for forgotten/change password (although I haven't actually forgotten mine) but they seem to depend on there not being a password for administrator. I don't have a password reset disk or any other disks for that matter. I wouldn't have minded doing a clean XP install and just loading the scanner software.

I was getting nowhere but then had a thought. On the Win 7 HP I often use the Character Map for special characters or simply pressing and holding Alt followed by the 4 digit number for common ones I use.

However, for cap R there isn't a keystroke ie Alt+•••• (I suppose it's expected one has a fully functioning keyboard!!). There is a Unicode string U+0052 indicated. I have no idea how to use it and whether or not it could be used to enter the character. I would really appreciate some help on this. If I could log on I know I could simply change the password using characters that I know work. Before I try more extreme measures I would like to try this. If it doesn't work then I guess it's a hack job....

Thanks in advance.
