Windows 8.1 is still in testing stage, so it's more or less obvious that compatibility, performance, and stability issues could be experiencing while trying out the OS update.
It now appears that some users are not allowed to launch Firefox and Chrome on their computers after installing Windows 8.1 Preview, so the built-in IE11 remains the only option when it comes to browsing the web.
“I updated to 8.1 yesterday and some strange things have happened since then. For one, now my PC requires a two step to turn it on. First I have to turn it on (nothing happens), then I have to hard shut down to turn it on again; for it to work. After that, Firefox and Chrome no longer work. The only browser currently working is IE and it does not do what I want to do so well,” one user wrote on Microsoft's support forums.
Now the biggest question is how many users actually want to stick to Internet Explorer if they can run Chrome or Firefox. Right now, Internet Explorer is one of the most criticized browsers out there and Microsoft itself has tried to fight the negative perception, so time will tell if users do agree to stick to this browser because of the errors found in Windows 8.1 Preview.
