Mitigation FAQs
Should I leverage the temporary mitigation?
Microsoft recommends that you consider implementing these mitigations if you are concerned your devices and data are at risk of being compromised or stolen. For example, if your organization’s employees take their work devices home or on business travel.
What impact to service availability/management could be caused by implementing the mitigations?
Implementing these mitigations will not impact service availability or management operations.
Do customers need to revert the changes made to mitigate the vulnerability once the security update to protect against this vulnerability is available?
No. The security update will maintain the mitigation's behavior once the security update is installed.
