以下来信息摘自微软官方博客：
Current List of Upgrade Blocks for the May 2019 Update (19H1):
1、If you have an external USB device or SD memory card is attached to your PC, you will be blocked from updating to the May 2019 Update. See this support article for details. If you remove any external USB devices and/or SD memory cards, the update should proceed normally. This issue will be resolved in a future servicing update for Windows 10. For Windows Insiders, this issue is resolved in Build 18877 and later builds.
2、If you have older versions of anti-cheat software used with games installed on your PC, you will be blocked from updating to the May 2019 Update. Some older versions of anti-cheat software may cause PCs to experience crashes after updating to the May 2019 Update. This block is specific to older versions of anti-cheat software. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of hitting this block, please make sure you are running the latest version of your games before attempting to update the operating system.3、
If you have redirected any Known Folders (for example: Desktop, Documents, Pictures), an empty folder with that same name is created in your %userprofile% directory when you update. Your Known Folders are redirected if you chose to back up your content to OneDrive using the OneDrive wizard, or if you chose to keep your content backed up during the Windows Out-of-box-Experience (OOBE). You may have also redirected your Known Folders manually through the Properties Dialog in File Explorer. This issue does not cause any user files to be deleted and a fix is in progress.
以下是中文（转自cnbeta）：Windows 10 May 2019 Update在以下情况下会被阻止升级： 1、计算机连接着USB存储设备或SD存储卡
微软表示，如果您的PC使用USB存储设备或SD存储卡，则无法升级到Windows 10 May 2019更新，简单的解决方法可以解决此问题，那就是拔掉它。 微软已建议用户拔除任何外部USB存储设备和/或SD存储卡以启动升级安装过程。 3、较旧版本的反作弊软件
如果您使用与许多热门游戏捆绑在一起的旧版本的反作弊软件，则可能无法安装Windows 10 May 2019更新。微软发现了一个错误，旧版本的反作弊软件可能导致Windows 10 5月更新PC崩溃。大多数游戏已经针对该问题进行了更新，微软正积极与受影响的合作伙伴合作。如果您的Windows 10 May 2019更新被阻止，请确保您运行的是最新版本的游戏。 3、已知文件夹被重定向
微软还阻止Windows 10 May 2019更新安装在具有任何已知文件夹的设备上，如果您已重定向任何已知文件夹（例如：桌面，文档，图片），则在更新时会在％userprofile％目录中创建具有相同名称的空文件夹。 如果您选择使用OneDrive向导将内容备份到OneDrive，或者您选择在Windows开箱即用体验（OOBE）期间备份内容，则会重定向您的已知文件夹。 您可能还通过“文件资源管理器”中的“属性”对话框手动重定向了“已知文件夹”。此问题不会导致删除任何用户文件，并且问题正在进行修复。
