Speedbit Video Accelerator and windows 8.1 no desktop network
Following applying the Windows 8.1 upgrade to a Dell PC running windows 8.0 Home premium all desktop applications were unable to connect to the internet! (not network printing, emails, etc.,)
Other applications running on the tiles were still able to connect fine (away from the desktop).
After some investigation, I noticed that when the tiled internet explorer sent a request to the internet it appeared to include speedbit in the initial url.
Checked the list of installed programs and found Speedbit was installed.
Removed Speedbit, restarted desktop applications all working correctly.
Speedbit may work fine, but it would be worth checking compatibility, in this case a reinstall of speedbit may resolve the issue following the upgrade to 8.1.
