Windows 7: Need Help Identifying Strange New Hidden Partitions Appearing In DM

Need Help Identifying Strange New Hidden Partitions Appearing In DM

Sorry if this is in the wrong section, wasn't sure where to put it. I multi-boot C: (Win 7), L: (Win 10) and N: (another Win 10) - all internal drives. T and up are on an external drive.
Look at this picture and tell me what the partitions are that I've arrowed and in particular the one I highlighted in yellow which is seemingly locked so I can't do anything with it. I can't move, merge or format it, properties say something about MBR. The other arrowed ones I assume are put there by Acronis T.I. These unknown ones are all new to me.
Note: Acronis is not supposed to do anything but a backup once a week of C: drive to V: drive, nothing else.
Or, is there a new Windows process insitiuted since I refused the Win 10 upgrade for C: ???
...and yes I've done an elevated disc cleanup on C:....several times.
Edit: sorry DM is confusing as the display is out of order, disc letter-wise.

Windows 10 creates those for recovery purposes during install.
This recovery partition is to hold the Windows Recovery Environment (WinRE)

Windows Disk Management does not support extending a partition where the free space is before the partition.
If you want to use that 8 MB of unallocated space on Disk 0, a program such as MiniTool Partition Wizard, AOMEI Partition Assistant, etc., should be able to do this.
Then you should be able to extend partition [O] to use that unallocated space.
I use MiniTool Partition Wizard for changes like this.

Here's an article that might help:
How to Extend Volume in Disk Management?

I always create backup(s) before making changes like this, i use Macrium Reflect.

I can't move, merge or format it, properties say something about MBR.
If i get a message like this from Windows, i wouldn't mess with it unless i am fully prepared for a restore and a Startup Repair.

You have partition O (letter) on Disk 0 (number), so that's makes this more fun, read carefully

LOL, thanks folks, will do some more reading and research. Just hadn't seen it before for some unknown reason.

Scanning hidden partitions
When I run Malwarebytes it gives me the option to scan partitions assigned a letter but what about: 1) The hidden factory recovery partition 2) The System reserved (100MB partition 3) The MBR (first 512 bytes on HDD). Can someone advise what software covers these areas for security checking?
