There is nothing for avast to solve since it is a Windows problem.
Look at the webboards, blogs etc from other av vendors (as well as independent sites) and you will see that the problem also exists with other av products and not just with avast.
As I said, Microsoft has acknowledged the problem and is working on a solution.
When something is green you can keep saying it is red but that doesn't change the fact it really is green.
Can you provide any link to prove what you said is not just pure imagination.
I cannot find any link showing Microsoft said it is Microsoft problem
I cannot find any link saying other than Avast there are other antivirus software having similar problem
Prove your point by showing any link.

This is not related to Avast at all.
Exactly because it is NOT an Avast problem
You are very funny
I searched and no single one person mentioned the word "Avast" in that Microsoft post. Even the outcome is similar with taskbar problem, it is totally different cause.
Comparing these two:
1. People report problem in that post in Microsoft doesn't use Avast, 0% ok? There is no Avast to uninstall to solve problem.
2. People in Avast report having taskbar problem 100% use Avast ok? You know what? Uninstall Avast 100% solve the problem, everyone over here who said uninstall Avast solves the problem!
It is totally two different cause even though the outcome is similar! OK, so car crash would let a person die, then can I say everyone die must be because of car crash but not something else like cancer? Microsoft post is like car crash then die but Avast forum case is cancer then die, yes both die (taskbar die) but because of totally different reason.
