Windows 10: Which "Healthy Recovery partitions" to delete

Hello I have a Surface pro Gen 1 (quite old but still doing great) running Win 10. It only has a 64GB SSD, so I need every bit of space I can get on there. There is currently 5 healthy recovery partitions at over 10gb. I would like to hang on to the repair partition, however their must be some that can be reclaimed? How can I work out which to keep and which to reclaim. A bit of background, It was upgraded from Win 8, never duel booted (but as you may see from the screen grab I am flirting with Ubuntu) and its on OS Build; 19042.928. Thanks for any Help

:)

Need to delete an old healthy Recovery partition.

Press Windows key + X

Click Disk Management

Select the Recovery Partition

Right click it, click 'Format'

You will receive a Warning dialog, click OK to continue.

The next step is to select your file system option, in this case, go with the default which is NTFS.

The formatting process will now begin.

Once complete, the drive will be displayed as a ‘Logical Drive’ in Disk Management.

Right click the ‘Logical Drive’ in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition. Right click the System volume (usually the C:\ drive where Windows is installed) then click the ‘Extend Volume’ option on the contextual
menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.
