Allow Non-Administrator Users to Access Windows 7 Home Premium Via Remote Desktop
After some experimentations I found, that I only need to import to the registry these values:

@=hex(22b):
That makes RDP connection work, so I can log in to my Win7 Home Premium as a regular user. I think the less we change the registry, the less are the chances that something goes wrong.
I also think, this is the minimal impact we have to make on the registry, as any of the 2 keys are omitted, RDP won't work as non-admin.
And for those who think this hack violates licence agreement: http://download.microsoft.com/Documents/UseTerms/Windows%207_Home%20Premium_English_a0cdb148-2381-47cd-bfc9-9b9102e0cb28.pdf
f. Remote Access Technologies. You may remotely access and use the software installed on the licensed computer from another computer to share a session using Remote Assistance or similar technologies. A “session” means the experience of interacting with the software, directly or indirectly, through any combination of input, output and display peripherals.
I may be wrong here, but in my understanding it's definitely allowed to access the machine remotely.
I found the registry secrets for this after quite a bit of searching, in the comments of one of the Remote Desktop articles, of all places. But, I did have to make some slight modifications.
First, I had to delete that Remote Desktop Users group that I had manually created (at the recommendation of another comment). (I created it with net localgroup "Remote Desktop Users" /add; delete it with net localgroup "Remote Desktop Users" /delete.)
Then, I imported a registry file as the SYSTEM account. I don't know everything this registry script does (I'll update if I gain more understanding as to what exactly it's doing), but it worked for me. Note the changes I made from the data in the source link: I changed the open-quote and close-quote characters to simple double-quote characters and added a slash and additional 0 character to each Aliases00### entry (so ...\Aliases0000234 became ...\Aliases\00000234).

To import the registry file under the SYSTEM account, I used the PsExec.exe tool, from the Microsoft TechNet "Process Utilities" PsTools package. It's a ZIP package, so you don't need to install anything. After unzipping the PsExec.exe file, I ran it as an administrator with the following command: PsExec.exe -s -i regedit.exe. From the Registry Editor window, I selected File > Import, and navigated the location of the registry file.
To import the registry file successfully, you don't have to use PsExec, but you do need to have permission to write to the HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Builtin\Aliases\ keys of the Registry, which you can gain by replicating permissions from the HKEY_LOCAL_MACHINE\SAM key to its children (sub-keys).
After importing the registry file, I added users to the Remote Desktop Users group (net localgroup "Remote Desktop Users" [username] /add), and with those users I could then access my Windows 7 Home Premium PC with Remote Desktop.
