The computer tower was a little delayed in shipping, but when it arrived it was packaged very securely in styrofoam.  My older HP Tower had been freezing up.  I could not access the Start Menu and my desktop icons even after taking it to a repair shop.  This computer is very fast and has all the bells and whistles I need for doing graphic art and musical creative projects.I am a little annoyed with a message I keep getting on the desktop everytime I start the computer.  It reads:"Your version of Windows 10 is out of date. Your device is running an older version of Windows 10. To continue to receive security updates and enjoy the latest features Windows 10 has to offer, you need to update your device to a newer version of Windows 10.*"  As far as I know this is a "newer" version of Windows 10.  I went to security updates, and I'm up to date!  I also went to the H.P. website and downloaded their program for maintaining the computer.  I found out 6 Drivers were out of date, and there were other critical updates that needed attention including the "BIOS", which is the problem I was having with my older computer.After scouring Amazon for a Windows 11 upgradeable PC, in customer reviews and questions people mentioned that it was upgradeable or they had already upgraded and had no problem.  I know Windows 10 is useable for a couple more years, but their criteria seems inconsistent.  In their list of criteria to upgrade to Windows 11 they have listed a minimal processor speed of 1GHZ.  This computer has a 3.70 GHZ processor, and is on another list of theirs as being acceptable.  What is it?  Acceptable, or not acceptable?  The other is the TPM needs to be 2.0, not 1.2.  It's very confusing!Other than those glitches this is a good computer.
