[SOLVED] Windows Server 2012 R2 Windows Update Errors (CBS Log)

[SleepyDude]

I'm not seeing a reason for the System Reserved partition be full!

Lets see if there are any shadow copies...

vssadmin delete shadows /for=y: /all /quiet

Edit: On my machine the SR have the same partition size and have 87,9MB free

No Shadow Copies.

 

[SleepyDude]

Do you have a 3rd party partition manager that can be used to resize the SR partition to 400MB?

An alternative would be this: “We couldn’t update system reserved partition” error installing Windows 10
the instructions for Windows 8/8.1 with MBR partition explain how to temporarily move the winre.wim to do the updates and latter copy the file back to the SR partition.

 

[samyitha]

No I do not have a third party partition manager. I'll give your suggestion a try of moving the winre.wim file.

 

[samyitha]

Your suggestion seems to have worked! Not sure why this has happened on more than one of my servers but I didn't know this is a reason updates would stop working. Wish there was documentation on this somewhere!

 

[SleepyDude]

Good. Usually in similar cases we found that some program stored some files on the system reserved partition when they shouldn't but in your case I didn't find any, only some of the files are bigger than the ones I have, I expect that after the updates some of them will get updated.

Many things about Windows Update are not documented or at least they aren't available to the public!


The most difficult part is that not always the logs are clear about the problem, not in your case:

Very good. I tried to look through the logs a few times and couldn't figure out what to look for! Glad you could. Thank you so much.

Just some background, I used a cloning software to migrate this VM and am using backup software that may have caused these issues.

 

[SleepyDude]

Yep the backup software's are the usual suspects for this problem, maybe the information is stored in a way that is not easily visible to the Operating System or something!
