I use a separate Vivaldi stand-alone browser for both,with no extensions and config. not to remember pws, but have used PP to make many purchases on all my browsers in recent years (usually low-cast items, like bike parts) with no thefts so far, thanks be to God in Christ. Pray and press.
I was forced to buy a Win 10 machine to manage my online prescriptions. It scares me. I had to give up a bunch of personal info to Microsoft just to get the O/S to start up. I've caught Brave storing my credit card info without asking me. Win10 regularly demands that I back up to Microsoft's cloud. I had forgotten what a PITA the updates from Microsoft can be. Too often this Win10 machine literally will not shut itself down for up to half an hour, unless I pull the power cord and yank the battery.
I hear you, but did you search how to bypass this? I myself installed W/11 using a MS account, but you should be able to do so without one, as well as W/10.
You can Turn off, disable, or uninstall OneDrive
You should also install MS sanctioned Autoruns for Windows (https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns) which you unpack, and run (best to r. clk. run as Admin) and hit Everything and see what all is loading, which you can deselect.
Also helpful is Process Explorer https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer
Of course, Windows update will often revert changes to autorun apps but if you want,
How to prevent Windows 10 updates
I thank God for such tools. May we use them for God and what is good in His sight.
Thank you for trying to help, but this is exactly why I am fed up with W10. I am forced to FIGHT the operating system rather than simply USE it, and as you point out this is a never-ending war because Microsoft can and will wipe out my adjustments with their "updates". Maybe this is fun for younger people. (Gives them a sense of accomplishment when they defeat Microsoft, however temporarily?) To me it is just a horrible waste of my remaining time and energy.
