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. |
