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.
