I have a system that started life with a fresh Windows 10 64-bit preview build installed on a blank drive with only one partition. This was later upgraded (using the "not keep any data" option) to Windows 10 Pro 64-bit release. The system drive now has a "Recovery" folder in the root with permissions restricting access to it plus a "$WINRE_BACKUP_PARTITION.MARKER" file also in the root. When I check the partitions on my drive I find that I have two Recovery partitions and that WindowsRE is configured for the latest recovery partition as shown by the following CLI dump (important information in blue).

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Recovery           300 MB  1024 KB
  Partition 2    System             100 MB   301 MB
  Partition 3    Reserved           128 MB   401 MB
  Partition 4    Primary            930 GB   529 MB
  Partition 5    Recovery           450 MB   931 GB

Windows Recovery Environment (Windows RE) and system reset configuration

    Windows RE status:         Enabled
    Windows RE location:       \\?\GLOBALROOT\device\harddisk0\partition5\Recovery\WindowsRE
    Boot Configuration Data (BCD) identifier: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

REAGENTC.EXE: Operation Successful.

My question is this: Is it safe to remove any of the following: Partition 1, Recovery folder, Recovery marker?
