System Requirements
 
 
To ensure
optimal performance of Comodo Client Security, please ensure that
your PC complies with the minimum system requirements as stated
below:
Windows Endpoints 
 
   
     
       
        | Windows 10 (32-bit and 64-bit versions)
 
 
 Windows 8 / 8.1
  (32-bit and 64-bit versions)
 
 Windows IoT |  
            1 GB hard disk space for both 32-bit and 64
       -bit versions  
            Internet Explorer version 11 or above   | 
 
     
  
 
    
     
       
         
           
             
               
                | Note about Windows XP / Vista
 
  
                    Older Comodo Client - Security versions still have support for Windows XP (up to CCS v11.1). However, Virtual Desktop features can not be used on Windows XP.
 
Comodo Client - Security is not officially supported on Windows Vista.
 
Comodo strongly recommends anybody still using XP or Vista to upgrade immediately. Microsoft ceased support for XP/Vista years ago and the number of serious vulnerabilities in these operating systems is almost innumerable. By using them you are exposing yourself to substantial risks which signature-based antivirus cannot protect you against. Windows 7
 
  
                    Microsoft
				ended general support for Windows 7 in January 2020. Devices
				running Windows 7 will only receive security updates if the user
				has purchased a 3 year extended security updates (ESU) package
				from Microsoft.   
                    Because
				of this, Windows 7 is no longer an officially supported operating
				system. Unpatched vulnerabilities introduced by the underlying OS
				can compromise the protection provided by CCS. For example, a
				weakness in a Microsoft API that CCS relies on can undermine the
				protection of CCS.  
                     
                      All
					CCS critical security features will continue to work on Windows
					7, including auto-containment, antivirus, and firewall.
					Similarly, you can also manage Windows 7 devices from Endpoint
					Manager and deploy security profiles to Windows 7 devices.  
                      We
					will also continue to fix critical and blocker issues for CCS on
					Windows 7.   
                      However,
					future CCS releases may contain features that are not
					included/do not work on Windows 7. 
  
                    We
				understand that many customers have clients who still use Windows
				7, and hope that this information helps you make an informed
				decision about transitioning those machines to Windows 10 / 8.1 /
				8. |
