Its an error when installing Windows on European versions. If you don't choose Internet Explorer, it does not create the "[system name]\user" group. The error will not be fixed by installing Internet Explorer after the fact.
Ohh I am seeing your issue now that I am doing it myself. I actually don't have this issue so I never gave it a go. I will write down the directions.
1. Press [Win Key] + R (this is the quick key for the run command)
2. Type in 'mmc'
3. Press [Ctrl] + M (this is the quick key for add/remove Snap-ins)
4. In the menu that pops up look in the left column for 'Local Users and Groups'
5. Highlight it by left clicking.
6. Press the [Add >] button.
7. Keep the window that pops up as is. (This should have the only selected item 'Local Computer')
8. Press the [Finish] button
9. Press the [OK] button
10. Right click on the [Groups] folder and choose 'New Group'
11. In the Group Name, type in 'Users'
12. Press the [Add] button
13. Press the [Advanced] button
14. Press the [Find Now] button
15. Highlight the 'Administrator' by left clicking it
16. Press the [OK] button
17. Press the [OK] button again
18. Press the [Create] button
19. Close the MMC window
20. On the next popup click [No]
