Windows 10 Enterprise LTSB 2016: Installing Windows Updates fails with error code 0x800F0922

Product Name: Thin Client t630
Operating System: Microsoft Windows 10 (64-bit)

Just downloaded the newest HP Image containing Windows 10 Enterprise LTSB 2016 for our HP t630 Thin Clients and tried to install the cumulative Windows Update April 2017 KB4015217:

 

1. Disabled write filter

2. Set windows update service to manual startup

3. Run installer for KB4015217 with success

4. Rebooted Thin Client to complete update installation. When booting up, Windows Update installation screen runs successfull up to 99%, then displays: we couldn't complete the updates, undoing changes.

 

Eventlog shows error code 0x800F0922

 

Tried installing previous cumulative update KB4016635 with the same results. Never had this problem with Windows 10 Enterprise LTSB 2015. Anyone out there with the same problems or any ideas fixing this error?

It might be too big while unpacking in the temporary folders in the Ramdrive.

Try to change the size of the HP RamDisk under the Control Panel (or if not enough to change the TEMP Paths).

After the successful installation it is recommended to change the RamDisk back to it's default value.

Thanks for your response. I both switched %TMP% and %TEMP% environment variables to C:\TEMP (exisiting folder) and tried installing again: no change - still the same error. I think the windows updates are not relying on the configured temp paths, they organize it on their own.
