最近3D VDI 用户反馈，Windows 10从v1803升级到v1809后，进入3D VDI后鼠标指针丢失，但是功能还是可以用的。又是一个蛋疼的问题。查了Citrix官网，已经是Citrix known issue了，而且在Windows 10 v1809上也很多其它的known issue。具体请参考Citrix官网：https://support.citrix.com/article/CTX234973
目前Citrix官网说正在working with Microsoft解决这个问题，给出了一个workaround，具体信息见下：
Issue 7 - Issue Description
Mouse pointer is not visible within a v1809 HDX 3D pro session. All operations inside the session are to be performed by keyboard using shortcuts. This issue is seen with Citrix XenApp/XenDesktop 7.15 only. This issue is not seen with later versions of XenApp/XenDesktop.
[LCM-4951]
Problem Cause
A change in mouse functionality API's is causing this issue.
Solution
Citrix is working with Microsoft to resolve this issue. As a work around, users could enable mouse pointer trails by following below steps:
- Click Start and type 'mouse settings'.
- Click on 'Additional mouse options'.
- Click on 'Pointer Options' tab.
- Select the checkbox 'Display pointer trails'.
- Click Apply and Ok.
作为运维人员要么自己帮客户改，要么给客户一个文档，让客户自己改。但是应该还有option3：组策略更改这个配置，google了一下，确实有这个注册表键值。
注册表键值路径：HEY_CURRENT_USER\Control Panel\ Mouse
然后新建一个String Value，命名为：MouseTrails
填写一个键值，键值范围是：1 ~ 7
1 – Minimum length trails.
4 – Medium length trails.
7 – Maximum length trails.
如果想关闭显示指针轨迹，把这个值设置为0即可。
