Masking the Windows recovery partition drive letter

Once in a while, things go awry in Windows for no apparent reason.
What happened to me today was that the recovery partition started showing up as a drive letter in my system. Unfortunately, that drive letter cannot be removed through the GUI in "Disk management" in control panel. The only way is to go to a command line and use DISKPART. Here is how.

1. Click the start menu
2. Type DISKPART
   
3. Type Ctrl + Shift + Enter to run as administrator
   
4. Type "LIST DISK"
   
5. Select the boot drive, usually disk 0, by typing "SELECT DISK=0"
   
6. Now list the partitions on the drive, by typing "LIST PARTITION" .
   
7. Select the recovery partition from the list . On my system, this was number 4, so I typed "SELECT PARTITION=4"
   
8. List the partition details by typing "DETAIL PARTITION"
9. Note the drive letter . This was N: on my system. Type "REMOVE LETTER=N
10. You are done . Type "EXIT" to leave DISKPART

Here is the output of my actual session :
