Expert tip:


Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

If clean-booting Windows does the trick, it means that one, or more, disabled startup programs or services were causing the disconnect error. The issue will likely return if you restore your original boot configuration without identifying the conflicting programs and services.
