title: Hyper-V not allowing the mouse in Windows Vista
body: <p>OK, I am having a problem setting up a virtual machine in Hyper-V, I’m not getting the use of the mouse. When I connect to the machine from Hyper-V and click somewhere I get:</p>
  
  <p><em><strong>Virtual Machine Connection</em></strong></p>
  
  <p><em><strong>Mouse not captured in Remote Desktop session.
  The mouse is available in a Remote Desktop session when integration services are installed in the guest operating system.</em></strong></p>
  
  <p>If I try the same from Virtual Machine Manager I get:</p>
  
  <p><em><strong>Virtual Machine Connection</em></strong></p>
  
  <p><em><strong>The mouse is unavailable in a Remote Desktop session when virtual guest services are not installed in the guest operating system.</em></strong></p>
  
  <p>The operating system is Vista Ultimate x86 Service Pack 2.</p>
  
  <p>I have installed the integration services disk (Action | Insert Integration Services Setup Disk). This runs through the installation, says it was successful and prompts for a restart. After the restart I log in, click on something and get the same error above.</p>
  
  <p>I have been Googling and as a result I have tried:</p>
  
  <ol>
  <li>Detecting the HAL </li>
  <li>Adding a 2nd CPU </li>
  <li>Installed all available Windows updates </li>
  <li>Trying installing the integration services again by running as administrator </li>
  <li>Building a new Vista machine </li>
  <li>Importing a Vista .vhd file from VirtualBox</li>
  </ol>
  
  <p>Nothing. No joy.</p>
  
  <p>Does anyone know how I can allow my Vista machine to accept the mouse?</p>
  
  <p>Thank you.</p>
