I upgraded my Dell Inspiron 15 1500 to Windows 11. Come to find out after 3rd party software help, the software was not completely compatible with Windows 11 and you only have 10 days from the upgrade to be able to rollback to Windows 10 and I exceeded that timeframe. I needed to go back to Windows 10. Seems simple, right? Below is the feedback I gave Dell: "Ajay did a great job trying to help me. After exhausting all his options, he told me this had to be escalated to Technical Support and he said they would be with me in 2-3 minutes. I waited 20 minutes and continued on with my day. TS finally got back to me almost 4 hours later. I contacted Microsoft and they helped me reinstall Windows 10 Pro to original factory specs." Here was their reply: "Hello Mark, Good Day! As the system was shipped with Windows 10 Pro we can assist you with the installation and activation of Windows 10 Pro only. According to guidelines, we can only downgrade the system if it was shipped with Windows 10 which was upgraded to 11. We are glad to know the issue has been resolved and hence we will proceed further and archive the case for now. Thank you."

My reply: "You're welcome. Thank you for poor service. I will reiterate the below story on Dell's review. You wasted 5 hours of my time and didn't even fix my warrantied computer and now have the audacity to want to charge me $99? This will also be included in my review of Dell. What a bunch or Morons!"
