My Dell laptop came with Win8, got auto updated to 8.1 and now to 10.
Now I find that there are 3/4 recovery partition on my hdd. I assume they are for 8, 8.1 and 10.

I want to delete those partitions and merge the space into C: partition. I have made USB recovery of Win10.
I googled for help on it and downloaded "EaseUS Partition Master" and "AOMEI Partition Assistant".
Before I start deleting and merging, my query is "Has anyone have similar experience ?"
Any advise on it is valuable for me at this stage.
To me, these partitions look way too small to be recovery partitions. Better investigate what is on these partitions first, before you create problems.
An easy tool to investigate what content is stored on those partitions is: EASSOS Partition Guru.
It is a small installer and comes in both freeware and commercial versions. The freeware one is fine for investigating.
This software has an explorer-like tool to look inside partitions, even if those do not have a drive letter or are hidden. And if you encounter files on those partitions that are associated with installed applications you can view those normally. Which makes investigating a breeze. The freeware version even allows you to copy files to different partitions or devices.
When you install Windows normally, besides the C:\ partition another small partition is created in front of the C:\ partition that contains all the required boot information. Lose this partition and you lose the ability to boot Windows at all! From that moment you will need to boot from your Windows installation media and see if the repair function can restore this or not.
Common size of this boot partition is 100MByte on a standard hard disk (with spinning platter(s)), and 350MByte on a SSD hard disk. All recovery partitions I have encountered so far, always have been several gigabytes in size. Usually between 4 and 10 GByte, depending on how much trial crap the manufacturer has included in their standard Windows installation. As the MS Windows installation files themselves are around 3GByte in size, drivers for the hardware take up the rest of the minimum recovery partition size of 4GByte.
The Windows disk manager isn't that capable in showing you what the actual purpose is of an partition. You will need more specialist tools for that. The earlier mentioned Partition Guru software is just one of those tools, MiniTool Partition Wizard is another (also comes in both freeware and commercial versions). In any case, what the Windows drive management software appears to mark as recovery partition doesn't have to be recovery partition in reality. The last partition in your screenshot, the one of 9.18GByte, that is
the recovery partition of the manufacturer of your PC.
