Windows 10: Upgrade from v1909 to v2004 - - Questions on Existing Software

Win10-Pro, v1909, Build 18363

Found this:

Re: The above.
I have a lot of old 32 bit software and a number of VB6 programs I've written.
I believe the old VB6 programs will run under a 64 bit OS if recompiled since I have source.
My question relates to all my other old 32 bit software (e.g Office 97), that I did not write.

Questions
-----------------
1) Any pluses / minuses from using v2004 ISO versus using Windows upgrade (if one can do this through upgrade) to v2004?
2) Will the v2004 install AUTOMATICALLY ensure (be seamless) the old software will run (e.g. move needed files from System32 to WOW if needed, --or-- set the old software so it runs in compatability mode without me having to reinstall or do a bunch of tweaks?
3) Microsoft already killed the HLP files associated with some of this software, any suggestions on best / easiest way to upgrade these HLP files to CHM or PDF, and hopefully get them to run from the old software instead as a separate file?

Storage Pool with Windows 10 v2004

I found a workaround solution: I installed Win 10 v1909, created the storage pool and then upgraded to v2004. No problem.

So I believe this confirms my suspicion that the problem is in the v2004 "Create Pool" function.

 

Windows 10 v2004

Currently rollback to v1909 . Dont install v2004 to main erp systems without testing properly.

 

Windows 10 v2004 Cannot Trim SSD

I have just upgraded to Windows 10 v2004. When I attempt to optimize my SSD drive I get the response "Optimization not available". The reason given in the event log is "The operation requested is not supported by the hardware backing the volume. (0x8900002A)".
This was working perfectly on Windows 10 v1909.

Hardware configuration is:

Sandisk 120G SSD

Marvell 91xx SATA 6G Controller v1.2.0.1039

I subsequently upgraded the Marvell controller to v1.2.0 1049, but it still does not optimize the SSD.

Any suggestions?
