Windows 10: Extend System Reserved space in windows 10

Dear Experts,I have upgraded from windows 7 to windows 10. How do I extend System reserved volume from 100MB to 1GB. I tried to do it with tools like "Disk Management" and "Windows PowerShell Admin". The partition "C drive" is next to "System Reserve". So even if I shrink C Drive by 3GB and make available "unallocated space", it does not allow to extend System Reserve space. Request to help and guide how to Extend System Reserved space from 100 MB to 1GB.

Clearing space in the System Reserved Partition

On MBR disk, Windows 10 requires a 500MB system reserved partition, while 100MB in Windows 7, so you can try to extend system reserved partition.



In disk management, you can only extend partition using the unallocated space next to its right side. so even if you shrink D: drive, the option to extend the efi partition is still grayed out. My suggestion is to use an third party software, AOMEI
Partition Assistant, both the standard (free) or the Professional(paid) version can extend partition as long as there is unallocated space on that hard drive. to see more information read:
