Windows 10: How do I make a file go back to it's original file type/state on Windows 11?

Hello,So, I don't remember how some of my files ended up getting associated with different file types/programs, but I probably, at one point, accidently clicked the "Always open with..." on these files, so now some of the file types are not the original file types anymore.Also, some of these files are "." files, so there's a dot in front of the file names, and aren't associated with any particular program. How do I get the "." files associated with nothing again? These "." files were downloaded for gaming/Homebrew purposes.Also, how do I make it so some of my files are back to it's original fi

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file1

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion

...

you get the idea. ( too lazy to put it in a for loop and test it.

or just open regedit and remove all the fileX from that key.

I need to convert Quattro pro files to windows Office 2007

http://office.microsoft.com/en-us/excel/ha010448731033.aspx

Install the Quattro Pro 5.0 converter
To install the converter for Quattro Pro versions 1.0 through 5.0 for Windows, do the following:

Click Start on the Windows taskbar, point to Settings, and then click Control Panel.
Double-click the Add/Remove Programs icon.
Click the name of the Microsoft Office 2000 or Microsoft Excel 2000 program that you have, and then click Add/Remove.
Click Add or Remove Features, and locate the Quattro Pro 5.0 Converter under Microsoft Excel for Windows.
Click Run From My Computer to install the converter to your hard disk.
Click Update Now.
Open a Quattro Pro file
To open a Quattro Pro file in Excel, follow these steps:

Click Open on the File menu.
In the Look in list, click the drive or folder that contains the file you want to open, and then locate the folder that contains the file.
In the Files of type list, click Quattro Pro 1.0/5.0 (Win) (*.wb1) if your files are from Quattro Pro for Windows versions 1.0 through 5.0, or click Quattro Pro/DOS Files (*.wq1). The former requires installation of the converter, as outlined above, before it appears in the list.
Double-click the file you want to open.
Notes

You cannot save files in the Quattro Pro 1.0/5.0 (Win) (*.wb1) format. If you open one of these files and make changes to it, you can save changes by saving as a Microsoft Excel Workbook (*.xls) or in another spreadsheet format.
You can save changes in the Quattro Pro/DOS format, but changes made using features that are unique to Excel may be lost.

You can open a file created in another program, such as Lotus 1-2-3 or Quattro Pro, in Microsoft Excel the same way you would open an Excel file. You can then save the file in its original file format or as an Excel workbook using the standard Excel save commands. Files saved as Excel workbooks might not retain all of their original formatting, and features and formatting of an Excel workbook might not be available in other programs.
