This issue occurs because consecutive taps are not recognized as double-taps or double-clicks by the remote computer. Specifically, the tap coordinates that are sent from the Windows Embedded Compact 7-based RDP client are not close enough to qualify as double-taps or double-clicks.
Note This issue occurs almost exclusively on touch screen devices on which the precision of touch is less accurate.
To resolve this issue, apply the following update.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

By default, this update is disabled after you apply it. To enable the update, set the DWORD value of the EnableDoubleClickDetect registry entry to 1. By default, the EnableDoubleClickDetect DWORD value does not exist, and you must create it in the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client
This update uses the values of the DblTapDist and DblTapTime settings. These values specify the time and space threshold settings that define consecutive taps or clicks as double-taps or double-clicks. The default value for the DblTapDist setting is 20 pixels, and the default value for the DblTapTime setting is 600 milliseconds. You can optimize these settings for platforms that require more accurate tap or click precision. To optimize these settings, change the DWORD value of the following two registry entries:
Note By default, these registry entries are not present, and you must create them.
Known issueAfter you enable this update, consecutive taps or clicks still do not work as intended in an application if the following conditions are true:
