Windows10如何開啟鼠標(biāo)顯示指針軌跡

最近3D VDI 用戶反饋，Windows 10從v1803升級(jí)到v1809后，進(jìn)入3D VDI后鼠標(biāo)指針丟失，但是功能還是可以用的。又是一個(gè)蛋疼的問題。查了Citrix官網(wǎng)，已經(jīng)是Citrix known issue了，而且在Windows 10 v1809上也很多其它的known issue。具體請(qǐng)參考Citrix官網(wǎng)：https://support.citrix.com/article/CTX234973

目前Citrix官網(wǎng)說正在working with Microsoft解決這個(gè)問題，給出了一個(gè)workaround，具體信息見下：

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:

1. Click Start and type 'mouse settings'.
2. Click on 'Additional mouse options'.
3. Click on 'Pointer Options' tab.
4. Select the checkbox 'Display pointer trails'.
5. Click Apply and Ok.

作為運(yùn)維人員要么自己幫客戶改，要么給客戶一個(gè)文檔，讓客戶自己改。但是應(yīng)該還有option3：組策略更改這個(gè)配置，google了一下，確實(shí)有這個(gè)注冊(cè)表鍵值。

注冊(cè)表鍵值路徑：HEY_CURRENT_USER\Control Panel\ Mouse
然后新建一個(gè)String Value，命名為：MouseTrails

填寫一個(gè)鍵值，鍵值范圍是：1 ~ 7
1 – Minimum length trails.
4 – Medium length trails.
7 – Maximum length trails.

如果想關(guān)閉顯示指針軌跡，把這個(gè)值設(shè)置為0即可。
