Leave it alone and let the Windows OS software handle it. Don't defrag it and don't assign a drive letter - ie keep it hidden.

This may explain a little of its original purpose when MS designed its original architecture:
reflect updates
It is post 24 that is the relevant post.

The PBR, bootmgr and BCD are key elements in this small partition that are critical in the MBR boot process. If you want these functions can be incorporated into the main OS partition using for example:
Bootmgr - Move to C:\ with EasyBCD

The 100mB system reserved partition must have ~ 50% free space if you want to use Windows inbuilt system imaging but most people here prefer system imaging software like (free) Macrium Reflect.

Thanks for the information and especially on EasyBCD which remains an option.

I guess theoretically System Reserved is better in security terms as the essential boot files are not mixed up with the C drive i.e. less susceptible to viruses.

Also is it possible that the defragmenter is misreporting? Is there any way to reinstall the Windows defragmenter?

I tend to think not.

I think one of the objectives of the system reserved partition was to facilitate mutibooting through the BCD (boot configuration data), it did have the bitlocked security facility but I was never comfortable with this.
I believe in keeping your OS partition and installed programs of a manageable size ( 256GB SSD should be plenty) and keep a number of system images. I keep large data on other drives and back it up independently. If a nasty hits me it will be a pain in the neck but recoverable I hope.

10% is the limit over which the system will auto-defrag but the system disc won't be defragmented.
