Windows 10: Win10 64 bit Pro

System says I have V1803. My computer has had no internet for couple of years. Today I hooked up to internet and tried to upgrade to V1909. Several hours later while 94% into upgrade INSTALL, I get a message saying unable to continue, system reboots and uninstalls what had taken hours to accomplish. NO error message was provided.

Windows 10 Pro 64 bit to 32 bit downgrade

There must be a step-by-step process to follow in order to move an existing OS from Win10 pro 64 bit to 32 bit. Any help with this would be greatly appreciated.

 

Migrating from Win7 Pro 32-bit to Win10 Pro 32-bit to Win10 Home 64-bit

My current computer started life with Win7 Pro 32-bit, and then I upgraded to Win10 Pro 32-bit with the free upgrade last summer. Now I'd like to switch to Win10 HOME 64-bit to take advantage of the extra memory I installed with my new mother board and CPU
last week on which Win10 Pro 32-bit is running.

Can this change to 64-bit Win10 HOME be accomplished using the activation code from my current Win10 Pro 32-bit (essentially the activation code from Win7 Pro), or must I purchase a HOME edition?

 

Win10 32 bit migration to 64 bit

I have an HP 6200 Pro running perfectly with a fully updated and activated license for Win10 Pro 32 bit. I am contemplating a migration to 64 bit Win10 Pro and have downloaded a 64 bit ISO file on a USB drive which is bootable right now. A 9/15/2015
Post on "Groovypost.com" says that on a UEFI based PC (as mine is), the USB drive must be made bootable with a utility such as "Rufus" making sure to format it in FAT32 and using the GPT Partitioning scheme. If the USB drive is already bootable, why would
this be suggested?

Just how it is for UEFI..

Also, MS' directions says that a product key will NOT be required if upgrading (in my case migrating) from an activated copy of Win10. Is this correct and if so, where does the new SW pick up the old activation digital entitlement - from the in place
activated copy of Win10 32 bit?

The computer configuration is known to Microsoft, and when 64-bit is installed, it takes note and activates automatically. All you have to do is skip the part where you are asked to enter a key code..
