How Long Can My Computer Hold On?

For the past ... um, I want to see the past several days, my computer has done this thing where it boots up just like normal, but then, when I try to put my password in, it won't move.  I hit the keys but the cursor just sits there, blinking a lot slower than normal.  I have to now restart it; upon its restart, I can put my password in to open up my computer.

My laptop is now old.  It runs on Windows 10.  It does not have the processor or the storage space to be upgraded to Windows 11.  Windows 10 is no longer supported as of last month, but I opted into getting updates for 10 for another year, at no charge, which makes me think then that Microsoft should have just said they won't support Windows 10 next year.  Anyway, I don't want to pay for something so expensive if I don't have nor want to.  But since it's getting older, other issues are starting to crop up.  Could something worse than this weird restart thing happen over the next year?  Possibly, and it might affect me being able to use this laptop at all.  Did I make the right decision to keep using this for another year?
