Can not update Win10Pro to 21H2

"Your device is missing important security and quality fixes." This statement shows up when I try to update Win10pro to 21H2. I tried several of the suggestions from MS support and others without success. I ran the Update Assistant, waited for the app to run it's routine(took awhile), and at the end I get the notice,
"you can not install Win10 on a USB drive." Yikes need some suggestions from the field.
Thanks you

Hi, are you running Defender, or a 3rd. party AV?
Do you get all updates from MS automatically? (Download and install).
Do you have any peripherals plugged into USB's connectors?
Have you Shut down your PC completely - waited - then Rebooted again?

Did you follow this process?

 

Yes, The Update assistant goes though it's process and then displays a notice, See pic attached. I removed PCMatic and now just running MS antivirus. If I remove 20H2, it will reinstall the update, and I end up in the same spot. This one has me stumped. I do not want to reinstall Win10 here if I do not have to. Any thoughts at this time?

 

Is the Update Assistant on a USB drive?
If it is copy it to the c drive and try again.

 

No I downloaded it from MS web site and resides on the c: drive

 

so much for that idea.
only other thing can think of is check boot order in bios that c drive is 1st.
had that error once - long time ago and can't recall what i did to fix it.

 

Already have done that and the mode is Legacy Boot

 

Your Toshiba was available for sale on June 6th 2010.
Your problem may be in the TPM 2.0 requirement of MS.
The message you attached would suggest that is the problem.

 

2.0TPM is active at this time. Not sure where to go at this time???

 

Have you tried this?
