I don't really know how to help you with the issue. 7+ Taskbar Tweaker shouldn't even be able to cause a blue screen of death - it doesn't use a driver or a service, and doesn't touch other processes except explorer.exe, which is by itself not a system process - it can be terminated without causing system instability.

Please see my answer here:

Such a feature, as well as other date/time customizations, are not planned.

You might be able to do what you're trying to achieve with a dedicated program, such as T-Clock (haven't tried it myself).

Please check the Chrome settings in Taskbar Inspector.

See the following screenshot, specifically the "Show labels" option:

The tweaker checks for update once every 24 hours. Perhaps you didn't have an internet connection on the first time, or some other issue such as a server error.

There indeed was an issue - if a new monitor is added while the option is on, the option is not applied on the new monitor. It will be fixed in the next version. For now, it's fixed in the beta version, please try it.

That's actually possible. Please see my answer here:
