Hi Alain Wehbe,
After resetting your computer, it is normal that the VMware vSphere Client is no longer available, as it needs to be reinstalled separately. To recover the controller (vSphere Client or vSphere Web Client), you can connect directly to the IP address of your ESXi host or vCenter through a web browser; the page will automatically provide the correct download link for your version. If you are using a standalone ESXi host, the built-in HTML management interface (accessed via a browser) is usually sufficient and does not require any additional installation. For HP ProLiant firmware version 8.70, please also ensure that your ESXi/vSphere version is compatible with that server model. Once the vSphere Client is reinstalled, you should be able to access your VMware environment again without affecting your existing virtual machines.
Please "accept the answer" so that it could be spread further to those in need too. If not, is there anything I can help you with? Please let me know.
