I have disabled the updates in registry,
There's your problem. Stop editing the Registry and/or running registry cleaners and your system will perform better.
As for the rest of your rant, you have every right to not use Windows 10. By all means format your systems and use something else.
Good luck!
Admittedly messing with the registry is dangerous but the issue here is Updates and their "messing with" the product that we bought.
You may feel insulting people who are tired of MS arbitrarily screwing with our systems is perfectly OK but remember We have the right to use the product we bought and not have that product constantly manipulated. I run Linux also and they can manage to build a secure system that doesn't constantly update.
