Windows April 2018 Update Fails: We couldn’t update the system reserved partition

“We couldn’t update the system reserved partition” is an error we’re seeing frequently when people try to install the Windows 10 April 2018 Update. The System Reserved Partition (SRP) is nothing mysterious. It’s a small space that Windows reserves on your hard drive so it can store boot information for Windows 10.  Some security apps and Windows itself may write to the System Reserved Partition (SRP) and consequently all the reserved space is filled. Microsoft should have already found a way to automatically increase the size of the SRP when doing a major version update, but so far they have not… leaving many people dealing with the “We couldn’t update the system reserved partition” error. This prevents them from updating to the newest version of Windows 10, until the error can be fixed.

    How do you know if you get this error? I installed my Spring update by downloading and creating an ISO. I never received anything regarding this SRP error.

      This does not apply to everyone. Only those people who tried to update to version 1803 and couldn’t … because the System Reserved Partition couldn’t be updated. If you updated to the new version then this doesn’t concern you.

    This kind of thing is why I changed to Apple products long ago. Windows was a constant frustration!

    My three computers updated to 1803. Now I can’t network between the three of them. HomeGroup is gone. They try to give instructions saying you can still use the network. But their instructions stink. They DON”T work. Now I’ve got three computers that can’t communicate with each other.

      I had a Home Network that worked fine 4 or 5 units, and now have the same problem. I hope and pray that Cloudeight will read and respond to this. I trust them.

    The best solution that Microsoft should undertake to solve the Windows 10 problems is to throw the complete O/S on the scrap-heap and continue producing and servicing Windows 7 ad infinitum.
    Not surprising is the continued upkeep of Windows XP as used by many Defence Forces and government departments in the USA, Britain and other countries.
