How to enlarge the System Reserved Partition in Windows 10

Toshiba / Satellite s50b 64 bit

Specs: Win 10, i5-4210U@1.70 8G
I have Windows 10 and the update to build 1703 fails with this error: We couldn't update the System Reserved Partition. I have AOMEI partition tool but am unsure how to ID and expand the Reserved Partition.

This is the same problem I had in attempting to upgrade from Windows 8.1 to Windows 10. Using one of the free tools I was able to enlarge the System Reserved Partition enough to get the Windows 10 upgrade before the deadline. I didn't keep notes for myself on which tool I used and how I was finally able to get the upgrade to install.
I've now got a hard drive that has unallocated space but evidently not where it's needed.

On Windows 7, the size is 100 MB whereas on Windows 8, it is 350 MB. Do you really need this space? I would recommend that you not delete or try to enlarge this partition. You can instead prevent it being created during Windows installation. If you are sure that you will not be using BitLocker, then you may go ahead.

The System Reserved Partition holds the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment and reserves space for the startup files which may be required by BitLocker, in case you use the BitLocker Drive Encryption feature. I am not sure that it has anything to do with the upgrade to Win 10 though.

Ewen ... thanks for your reply. I do not intend to use BitLocker. The System Reserved Partition is already in place. I have downloaded three different tools to manage partitions and each one shows a slightly different image of my hard drive.
I know without doing anything ... my Windows 10 will not get the update to version 1703. That may not mean anything to the performance of my system. Also, not sure I will continue to get regular updates since I don't have 1703.
I've backed-up all my data ... I've also used the back-up within Windows 10 to back-up my system on a USB for recovery.
The view in MiniTool Partition Wizard shows 1.23GB with all used and it's labeled as OTHER ... and GPT (Reserved Partition).

Directly beneath that is 22.18 GB of unallocated space.

Directly ABOVE the GPT (Reserved Partition) is
100MB (12.78MB unused) ...FAT32 ... GPT (EFI System partition) ... Active & System

I hope to get some guidance on whether to do nothing ... or attempt to enlarge the appropriate partition (whichever one that may be).
Again ... Thanks

My knowledge of the manipulation of partitions is somewhat limited to a "need to know" basis and hopefully someone with more knowledge will reply. I was advised though sometime back to leave the System Reserved Partition well alone and as a result I have never done anything with it. My Win 10 sails merrily along regardless.
