Windows 10: Windows 11 upgrade ruined PC Storage/softwares

I've just recently upgraded my laptop from windows 10 to windows 11 but I regret it now...After updating, a lot of my software's have gone "missing". I am unable to find them using the laptop search bar. The shortcuts are missing. It's as though majority of my essential software's have been uninstalled including all my MS office softwares word, ppt, excel etc.Yet, my storage size has still been consumed by my "missing" softwares yet the maths does not add up?

Upgrade to Windows 11

I want to upgrade my OS from Windows 10 to Windows 11. I have run the compatibility software and got the message that says my Windows 10 software is not compatible with upgrading to Windows 11. I'm looking for a point & click application that will make my Windows 10 OS upgradable to Windows 11 or a file that will provide step-by-step instructions on how to accomplish the upgrade to Windows 11. I expect a list of files/applications that will not run in Windows 11 because my PC is not capable of running the new applications w/o hardware upgrades.

 

Upgrading to windows 11

I have a few questions about windows 11...

1. How many GB it is? when my pc suggested the upgrade yesterday, it said it's about 4GB just want to be sure.
   
2. I'm using a windows 10 pro so if I upgrade, will it upgrade to a windows 11 pro?
   

 

Can I still upgrade to Windows 11 if I change the storage drive, CPU, and motherboard?

My PC does not meet the minimum requirements to upgrade to Windows 11 (Pro). In order to accommodate this upgrade I've bought a new storage drive, CPU, and motherboard. The new drive is much faster than the other drives, so I'd like to use it to store Windows instead of the original drive.

• Is it possible to immediately activate Windows 11 after I install it on the new drive using an installation disk?
  
• In case activation isn't possible because I don't own Windows 11 yet, would it work if I installed Windows 10 first and then upgraded to Windows 11 instead?
  
• Or would it not activate either copy of Windows 10 or 11 because my PC isn't recognized as the original due to the changed parts?
  

I would very much appreciate any help or suggestions.
