I tested QTTabBar for about a week. It works OK and does not destabilize Windows. It does not destabilize File Exporer either except File Explorer cannot browse my Android Phone (via USB connection) while QTTabBar is installed. This is the only problem that I have detected.
After many more months of testing QTTabBar, I must say that it works great and does not cause any problems in Windows, except I cannot create folders on my Android phone via USB connection (not a big problem).
