Windows 10 从很久以前就开始有这个问题，升级或者全新安装以后开始菜单磁贴无法正常工作。拖动一下就会卡死，或者修改布局并重新登录以后就会重置成以前的样子。
此问题影响至少 1709 和 1803 版本，并且能在全新安装的系统上复现。
搜遍谷歌，找到一种解决方法，是删除注册表中对于开始菜单磁贴的缓存。
Windows 1709
管理员版本 Powershell 下执行：
1 | Remove-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$start.tilegrid$windows.data.curatedtilecollection.root' -Force -Recurse |
或使用注册表编辑器手动删除：
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount 下的$start.tilegrid$windows.data.curatedtilecollection.root 项目。
Windows 1803
管理员版本 Powershell 下执行：
1 | Remove-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\' -Force -Recurse |
或使用注册表编辑器手动删除：
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount 下以的 $start.tilegrid$windows.data.curatedtilecollection.root 结尾的项目。

It has been a long while since Windows 10 had issues with its start menu layout, such as dragging and dropping icons causes crashes, or layout gets reverted after signing out and in. At least 1709 and 1803 fresh installations are affected.
A strategy to mitigate the issue, according to the other end of Google, is to remove the cache store in the system registery.
Windows 1709
Execute the following under Admin Powershell:
1 | Remove-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$start.tilegrid$windows.data.curatedtilecollection.root' -Force -Recurse |
Or, using the Registry Editor
Navigate to Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount and delete $start.tilegrid$windows.data.curatedtilecollection.root item.
Windows 1803
Execute the following under Admin Powershell:
1 | Remove-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\' -Force -Recurse |
Or, using the Registry Editor
Navigate to Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount and delete item ending with $start.tilegrid$windows.data.curatedtilecollection.root.
由于问题的普遍性，特留下中英文两版以供查阅。
