This all started with the *&^%$#@ update for W-10 that MS forces on people whether they want it or not. It's infuriating that MS does this. It messes up everything. I lost all my cookies and passwords. All had to be looked up and reentered. Time consuming and tedious. W-10 updates also removes OutlookExpress since MS wants people to BUY their office apps. I lose all my contacts and all my saved emails. The @#$%^&* nerve of MS. So that had to be reinstalled again.
Firefox also updated itself for the first time not giving people a choice. It did that at the same time - it had to be related to the W-10 update. So I lose all my contacts, my saved email and more. I had to reinstall that. How dare MS decide for us what to force on us against our will.
