Windows 10: Upgrade 8.1 with Win 10 OEM without losing programs

I mistakenly ordered Win 10 OEM to upgrade my Win 8.1 instead of the Retail Package and would like to know how do I install Win 10 OEM without losing all my programs including myMicrosoft Office and associated programs?If I backup my Hard Drive onto an external hard drive will they, the 8.1 programs run in win 10if I try to use them?I know that a new install OEM will format and remove all data on my Internal HD and that's whatI'm trying to avoid.thanks for any assistance.

if you upgrade to Win 10 from a OEM Win 8 Computer be aware

if you upgrade to Win 10 from a OEM Win 8 Computer be aware

if you have a OEM Windows 8 computer (Hewlett-Packard,Acer,Toshiba ect.) and installed Windows 8.1

it adds a extra 350mb recovery partition

now if you had to restore back to Windows 8 from the OEM recovery Partition the extra 350mb recovery

gets left on the hard drive

now from a fresh install back to Windows 8 from the OEM recovery partition you upgrade to Windows 8.1 it adds another 350mb recovery partition so now there is 2 350mb recovery partition and if you keep going back to Windows 8 from the OEM recovery partition
and upgrade to Windows 8.1 it adds another

Windows defrag see's these 350mb recovery partition as Local Disk (\\?\VOLUME and can not defrag them

i asked this question on July 8

upgrade to Win 10 but Too Many Recovery Partitions from Win 8.1

Jayant Gupta a Microsoft Support Engineer in this post say's

" i would like to provide you with the information that, if you have another HD then I would suggest you to re-install the OS and get ready to upgrade to Windows 10. Having too many reserved partitions might cause Windows 10 upgrade to fail "

Win 10 upgrade from win 8 OEM

Is it possible to directly upgrade from OEM installed Win 8 to win 10 using official iso without internet and the need to enter keys which is not possible to skip while installing win 10?

 

Upgrade a Win 10 home OEM to Win 10 Pro OEM with Win 10 Pro OEM Key?

I recently purchased a laptop that has an OEM version of Win 10 Home on it.

I verified this by using : slmgr -dli.

Previously I had purchased an OEM Win 10 Pro Key.

Can I use this OEM Win 10 Pro Key to upgrade the OEM Win 10 Home to the OEM Win 10 Pro.

If so what are the steps to accomplish this?

In addition, I assume that is this is possible, that the current product key will be updated to the new product key?

The reason I am asking this is that it's my understanding that these product keys are tied to the bios on a name brand laptop.

TIA
