Windows 10 is not out of the box supported on ESX 5.5, unless you're running 5.5u3. One of the issues is that earlier versions do not have a compatible video driver for Windows 10.
However, for older versions of ESX 5.5, you can manually download the VMWare Tools and install them:
If your vCenter server has a self-signed certificate, you will get a warning about this when connecting to it from vSphere PowerCLI. You can disable this warning through PowerCLI with the Set-PowerCLIConfiguration cmdlet.
Set-PowerCLIConfiguration -InvalidCertificateAction Ignore
After making the change, new connections to the vCenter server will no longer produce a warning about the certificate.
You may have noticed that running the VMWare vSphere client on a display with higher DPI settings causes problems with the mouse cursor alignment when working inside a VM. This is because of a mismatch between the DPI settings of the VM and the DPI settings of your computer.
To resolve, right-click the shortcut to the client, go to the Compatibility tab, and enable Disable display scaling on high DPI settings.
The downside of this method is that there will be misalignment of some parts in the client, but it is still workable and moreover, it solves the mouse issue in a VM.
When attempting to install or upgrade VMWare vServer server or its components, you may get the following prompt:
Please insert the Disk: 1
If you click OK, the message reappears. Clicking Cancel results in the installation to roll back.
Copy the entire installation files to a location on the local hard drive and run the install/upgrade from there.
When running the installation from the local hard drive, and you get the error Provided password is wrong or empty, reboot and re-run the install from the local hard drive.
When attempting to install VMWare Tools on a Windows 2000 VM, you may get the following error:
To resolve, you need to install Security Update for Windows 2000 (KB835732) (requires SP4 as well).
