I upgraded to Windows10 Pro 32bit from Windows7Pro 32 bit early in August and that went pretty well. The only program I had to uninstall/reinstall was BitDefender as I suppose the way Anti-virus programs work in Win10 is different, but there were instructions on the BitDefender website on how to do it. However after the Aug 10 Windows 10 updates I have not been able to make ANY of the web browsers work Chrome (my default), MS Edge or IE. I tried both wired and wireless connections and while the computer told me I had connections to the internet none of the browsers worked. I kept getting messages that they could not reach any of the websites I tried. I uninstalled the three Windows 10 updates from Aug 10 and rebooted and still could not get any browser to work. I went online from another computer and found fixes from 2013 for browsers not working in Windows 7 - I didn't think they would work and they didn't but I had to try anyway and could not find anything for Windows 10.
In the end I went back to Windows 7 and my browsers started working again. UPDATE - actually only Chrome is working again. If I try IE it freezes my computer - I assume when I did the upgrade to W10 MS changed it so that it no longer works with W7. I will remove it and reinstall. I really don't use it that much but some commercial websites I use (specifically utility companies) - only design their websites to work with IE so I get some weird results if I try to use Chrome. I figure that may be the same with Edge which is why W10 has both.
UPDATE2 - can't uninstall IE as it does not appear in list of programs. If I start the IE 11 setup program it won't run because it says it detected a newer version already installed. This really ticks me off.
UPDATE3 - Can't download anything from Chrome now. Something happened to how Privacy is determined so Chrome will not allow me to download anything. Well, this was the last 32 bit computer I owned and its 6 years old - I wanted to use it for another year, but in order to use it properly as a Win7 machine I would have to reinstall everything from scratch which isn't worth it to me, so I'll upgrade it again to Windows 10 and try to figure out why the browsers don't work, I guess the first thing I will do is remove all 3rd party software and see what happens, starting with BitDefender.
Has anyone else experienced a similar issue with their upgrade to Windows 10? I will probably make another attempt after the next Windows 10 update - I am using an older spare computer to test whether the Windows 10 upgrade will work or not so I'm glad I did not do this on my regular computer. But I have not yet found anything about browsers not working on Windows 10 when I google it.
FINAL UPDATE - problem was with Bitdefender Total Security 2015. After going to the BD forums I found several people had the same issue. To fix it you needed to uncheck the Block Internet Sharing option in the Firewall. While that seemed to have no problem with Win 7, it caused a problem in Win 10. First though, I had to reinstall Win 10. I would not recommend rolling back to Win 7 from Win 10 since a lot of programs did not work properly and you have to reinstall them from media since I could not download after the rollback.
