Cause of We Couldn’t Update System Reserved Partition Error

There may be several reasons this error pops in front of your face out of nowhere. Out of those, one common reason may be an internal error in the system reserved partition. Another reason may be insufficient disk space in the system reserved partition (SRP) for an upgrade. Different versions of Windows have different memory allocated to SRP. Like, on Windows 7, it takes 100MB disk space, 350Mb on Windows 8, and 500MB on Windows 10.update system reserved partition error

Now that we know the cause, it becomes slightly comfortable to fix this problem.
