Hey there, 3H.
Allow me to chime in and share a few details about the Super Clean Install process.
A Super Clean Install fixes some issues that keep you from opening file and a few other situations that is necessary to completely remove QuickBooks Desktop from your computer. This process replaces all files used to install it.
I recommend performing the detailed steps in the article above provided by my peer, LilyC.
On the other hand, I suggest checking with an IT expert to help you with your Windows concern.
That should do it. Don't hesitate to let me know if you have other questions. Have a wonderful day.
