Windows 7: Unable to rename Users folder

I have migrated my Windows 7 OS to a SSD, but my Users folder is too large to migrate. I am going to set a junction between C:\Users on my SSD and F:\Users on the HDD where my OS was originally. The instructions I have read indicate that I need to rename the C:\Users folder in order to set the junction, since it will not work if there is still a folder named C:\Users. However, there is no ""Rename" option available when I right-click on C:\Users. In fact, several of the folders in the root directory of C:\ have no "Rename" option.

How do I get the option to rename this folder back?

Thanks.

I would not move the Users folder, just move Documents, Downloads, etc using the location tabs.

I say this since it can cause issues with the system,
