Windows 10 Update error - 0x800F0955-0x20003

Hi,

I am having trouble trying to update from 1607 to anything higher than 1607 on multiple work PC's. The only thing that seems to work is clean install but I want to see if there are other ways to update as the process of clean install is very long considering the amount of PC's that are stuck on 1607.

I have tried multiple methods such as In-Place Upgrade, Update Assistant, Media Creation Tool (ISO+USB), clearing SoftwareDistribution, renaming catroot2 and Windows reset but I am still unable to upgrade from Windows 1607.

Whenever I use Update Assistant, I am helplessly stuck on 99% on every PC I have tried. I have waited around 2 days but still on 99% so that never works. Using In-Place/Media Creation Tool didn't do much either as the updates would always stall around 70%.

I believe all these 1607 PC's have a problem with SNMP(??) as I looked up logs from some PC's and its the same error. I have disabled SNMP from Windows optional features and tried using the methods above, but still the same result.

Here is the log:
Code:

If anyone could help me out, it would be much appreciated.

Many thanks,
Jhin

cann't install update windows 10 code error 0x800F081F - 0x20003

We couldn't install Windows 10 We've set your PC back to the way it was just before you started installing Windows 10

0X800F0830 -0X20003
The installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation

A bit of googling showed a couple of possible causes for the problem, but they don't seem applicable - I'm not using 3rd party antivirus, and C: has sufficient free space (~35Gb free). Any suggestions on a fix?

can this problem be solved by installing new windows? whether the windows activation code is the same as that listed in the windows explorer-this pc- properties, at the bottom.
