Genesys Testlab makes a best-effort pass of validating all released updates for supported Microsoft operating systems. Any issues found within specific patches will be noted in the table below. Microsoft’s release process has proven reliable, and there is low risk in applying generally-available updates. Our recommended best practice is to apply all current patches into a test environment for validation before deploying in production. This allows customers to align with any required security or patch management schedules, while protecting the production environment from any unknown impacts.

Testlab cannot guarantee complete compatibility and will not identify the impact of Microsoft updates on out-of-support products, or supported versions that are not updated to the most recent CIC patches/updates. We do not validate Limited Distribution Release updates, generally labeled 'hotfixes'.
