How to fix a broken Windows 10 start menu
Last year, the start menu on my Windows 10 user account stopped working. When I'd press the Windows button, nothing would happen. There were also issue with a few buttons on the taskbar. Some of them didn't have an icon and when you pressed them, they did nothing. After much searching and frustration, I found out that the TileDataLayer directory under my account may have been corrupted. Unfortunately, I didn't find any tool to fix that or even determine with some certainty that this was the issue. However at this point, I didn't have much to lose, so I went ahead and reset it manually.
