Some months ago, only having recently acquired the new PC with Windows 7, I attempted to rename the public music, videos and pictures folders to 'Public Music' etc. in order to make them easier to distinguish from the other users' folders of similar names when they were both added to libraries. Occasionally afterwards, I noticed Windows seems to have created (or re-created) a 'Public Music' folder (etc.). As this was leading to more confusion, I attempted to rename them back. However, I seem to be getting in a mess. The folders did not seem to have a location tab. Nor did they have the restore default button on the properties dialog box. I was getting funny results with files not appearing in Windows Media Player and the Windows backup failed with messages such as 'Backup encountered a problem while backing up file C:\Users\Public\Public Music. Error

The system cannot find the file specified. (0x80070002))'. How I'd like to be able to go back and start again armed with a bit more knowledge this time.
I've now, in desperation, deleted the public folders and followed the instructions in this post. However, after a number of restarts, there is still no sign of the public folders being restored. Am I right in thinking that Windows will recreate the missing folders at some point? (After all, it seems to have done so in the past). Is there anything else that I need to do?
Hope someone can help.
