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

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