Windows not genuine after partition resize

I resized a partition (the boot partition) using gparted off a linux boot disk (should be the same as any other program, though) after removing a backup partition which was never used. I rebooted the computer, and it ran startup repair. After startup repair had finished, I rebooted again. This time it boots into windows and gets to the login screen. I can log in, but it comes up with "welcome", followed by "preparing your desktop". It then loads a temporary profile. From there, I tried to load the control panel to load system so I could input the product key, but it wouldn't load the control panel because of an error I can't remember - but it displayed something like this:
"{random nums and letters}"
Does anyone know how to make it boot from a permenant account?

Thanks a heap in advance.

PS. I have access to command prompt as admin, and regedit. Also, I have another windows partition which I might be able to boot from. I also have a linux bootable CD, if that helps (can move around files from there)

your profile is corrupt for some reason. we will fix that later. Create a new account with admin rights and logon under that account. is windows genuine then? works that accountand has it a permanent profile?

to make your windows know that it moved some partitions
-go to "defrag" and select the defrag scheme. Disable any ghost volumes from the list
-go to system properties and disable restore points on ghost volumes. enable it on your real volumes
ghost volumes are something like "C (missing)". After that try to make a manual restorepoint

By backup partition, I mean backups of files, not of the system itself. I don't use system restore.
BTW, this is for a friend of mine - I personally take backups of the whole system, but he has no backups. We can't see any ghost volume as we can't open windows explorer. I will try and contact him about the suggestion for making a new user account over the phone though.

ghost volumes are not visible in explorer. Reread my description!

in reply to Kaktusoft:
I know they are not visible, but my point was that:
a) we can't open the control panel, so can't access system restore, which, by the sounds of it, we need to access this setting.
b) we never used system restore

Correct me if I'm wrong, but that step isn't nessecary if I don't use system restore - right?

And to answer theogg, this is a custom built computer, so there was no OEM, and my friend doesn't use backups - only reason (however, we do have the windows install CD)

Error message: "The User Profile Service failed the logon. User profile cannot be loaded
do step 1

It doesn't come up with that error, but it's just starting to prepare the desktop now.

Ok. Computer has loaded the desktop. It comes up with the error "no such interface supported", on both the old user account, and the new one we just created.

When we try to open my computer, to load the disk defrag tool, it says "explorer.exe not supported".
EDIT: we can access the defrag tool through command prompt - defragging all drives now (so could be a while)
We still can't open the control panel.
