W10 1809 to 1903 update

Lenovo ThinkCentre E73, I have updated from W10 1809 to 1903 and the PC has now gone really slow and having issues with admin rights, I have chkdsk'd and scannow'd' but no issues found. Tried an inplace update in case windows was corrupted and get the
message some hardware on this PC is incompatible with 1903 update. Can anyone shed any light in these issues please. I have had to revert to 1809 to make the PC usable again. Any suggestions please ? Microsoft have said Lenovo are responsible and Lenovo have
said Microsoft is responsible, which does not help me one bit.

 

Windows 10 Update 1809

I am trying to update a WINDOWS 10 PRO x64 from 1803 to 1809. This is a clean install that I performed due to the fact that 1903 blocked a specific app that is required for our Users. The clean install has been updated to 1803 but, I would like to update
it to at least 1809. I have gone to the Microsoft Catalog and searched for 1809. The Catalog gives a long list of 1809 options but, none will install an says Not Applicable to Your Computer.

So, I have read that Microsoft had trashed the 1809 and moved onto 1903. Can anyone point to the proper download or if there is a trick I can do to keep my system at 1809?
