Here is a advanced registry editing tool The home of Spybot-S&D!
And are you having this problem on other computers as well? (excuse me if this has been clarified or asked before, ive only had 1 coffee this morning)
And are you running a localized version of windows?

H2SO4 - please don't mock; don't you know he made the trains run on time? In Italy?

No I only have this problem on computers running windows 7. I managed to modify the key, but to no effect.

This forum should be renamed "Comical geeks forum" or "Sitting down comedians".
Does anybody know how to answer my question???

Look if you arent finding your answer's then you can always look somewhere else.

Now, to your issue.

I have tested this working on a Windows 7 RTM installation.

Please when you create the new registry key, be sure to make it an "expanded string" key

also do not include the qoutes when entering the value into the key.

I am exporting the key and will attach it to this post for you to try importing, but I think you will still need to take ownership of the key first.

Thank you for your answer and suggestions, finally somebody gave me a serious answer. By the way I posted this question to other forums, with no result.
I had already made myself (i'm Administrator) owner of the key and all the subkeys. I downloaded the reg file attached to your post and executed it successfully. Unfortunately the Icon's name is still "Computer"
I am running Windows 7 Ultimate on an Asus-Lamborghini VX2s with 2 GB RAM.
I exported the key after executing your reg file and I'm attaching the exported key to this reply.
Thank you again. Hope to find a solution soon.

By comparing the two reg files, I dont think the change was actually made to the localizedstring value, could you open regedit and look at the value that is actually set and post it.

Sorry but the two files are perfectly identical. I converted your LocalizedString.reg into a text file LocalizedString.txt (attached) and then exported my modified registry key into a second text file MyLocalizedString.txt (attached) and then compared the two files with DiffDoc.exe that did not find any difference.
It is evident that some block in windows 7 does not allow this tweak to work. I recognize that you have been the only one trying seriously to answer my question. Unfortunaltely it did not work. Thank you for your help. I posted my system configuration.

Step I had to take to make the change and get it to show was to go into permissions and take ownership of the key then assign myself rights to read and write. Works for me I have the desktop icon now named to whomever is logged in. Check your permissions and ownership. Delete the key and try again.

As for H2S04, he is right. Leaving any workstation open whether in a "public" or office environment is a serious security breach and needs to be addressed. Last place I worked there was a bank of office right next to the employee exit and entrance. Not only were all laptop desktops to be locked but so were the doors to the offices if not occupied.
