Good Day everyone,
I'm hoping someone can help me, I am really struggling to upgrade windows 10 to any version, I will list all the various things I have tried but I'm no expert this is from reading multiple forums and troubleshooting steps.
These are the steps I've taken to troubleshoot the Windows 10 Upgrade, I'm trying to upgrade from version 1809 - 2004 all systems are 64bit windows 10 enterprise.
I will give an example of one of the systems and some common issues I've found in all of these systems.
Initially I've updated all the drivers and BIOS and firmware for the SSD drives.
Pushed out the 2004 feature upgrade which fails
3.Run Setupdiag which refers to this error :

4.Checked the scanresult.xml file in C:\Program Files (x86)\DesktopCentral_Agent\logs\Panther which returned the following errors
<DriverPackage HasSignedBinaries="False" BlockMigration="True" Inf="oem162.inf"/>
<DriverPackage HasSignedBinaries="False" BlockMigration="True" Inf="oem161.inf"/>
<DriverPackage HasSignedBinaries="False" BlockMigration="True" Inf="oem163.inf"/>
OEM162 - Microsoft XPS Document Writer
OEM161 - Microsoft Print to PDF
OEM163 - HP Wireless Button Driver
I removed OEM162 uninstalled the driver, OEM 161 & 162 I had to disable this under windows features and run pnputil to remove the driver packages from the machine and delete the compatscancache.dat file from C:\Program Files (x86)\DesktopCentral_Agent\logs\Panther
6.Restart the machine
Deploy the feature update 2004 which fails
Ran setup diag which returns the same error :

I've also tried removing our Mcafee antivirus and redeploying but get the same error. The only thing I have not tried which I'm in the process of trying is to remove drive encryption.
If anyone could help me with either alternative troubleshooting steps I would really appreciate the help, I'm under massive pressure to upgrade 1400+ machines in line with compliance requirements.
Thank - you Kindly
