Windows 10: System Reserved Partition Question

My system reserved partition keeps expanding!! How do I limit the size?

I have checked the forums and internets but not come up with a clear answer

A few days ago MS disk image failed because there was not enough free space in the system image partition for the shadow copy. The existing 100mb partition was 98% full.

I expanded the partition to 250mb and everything was fine.

I looked today and the 250mb partition is now 80% full at about 200mb. It seems to be a relentless blob devouring my SSD. *Eek

I can of course keep enlarging the partition but would prefer to some how limit it. My understanding is that the actual boot sector files are no more than 30mb so what keep expanding into the remaining space.

System is Windows 10 pro/4GB RAM/240GB primary boot SSD with 250mb "system reserved" partition with the remainder a second OS partition. Both partitions are NTSF. System has 3 other data drives of varying size installed.

Is there any administrator tool or registry change I can make to resolve the issue?

The current active partition is compressed

Actually, I have answered my own question. Somehow, my system drive has only one partition - there is no system reserved partition. I will just decompress my drive.

 

how to remove "System Reserved partition" from Defrag?

Hello,

To answer your questions:

• When you install Windows 10 on a clean formatted disk, it first creates a partition on the disk at the start of the hard disk. This partition is called the System Reserved Partition. Next it use the balance unallocated disk space to create your system drive
  and install the operating system. To see the System Reserved Partition, you will have to open Disk Management.
• To remove "System Reserved partition" it would be easy to just leave it be. Windows hides it by default instead of creating a drive letter for it. Most people will never notice they have a System Reserved partition, and Windows will only show it to you
  when you use disk-partitioning software. This partition is mandatory if you use BitLocker or want to use BitLocker in the future. Every drive is made ready for BitLocker while installing Windows.

On a MBR type system - the System Partition is 500MB
this is to allow for boot files and winre..

or use diskpart to assign a drive letter to that partition - and see what is uses the space..

 

Interesting to know. I will expand it to 500mb. Yes old hardware with MBR. Was it initially at 100mb because this was an inplace upgrade from windows 7? Would a clean install of Windows 10 have resulted in an MBR partition of 500mb?

 

Yes to all questions. Prior versions of Windows created separate partitions for System (boot files) and recovery partitions. The newest Windows 10 builds combine the System and Recovery partitions.
