The February 2019 Security and Quality Rollup for Windows 10 update 1809 was released earlier this week. We have received multiple customer reports of issues when a customer has installed .NET Framework 4.8 Preview then installed the February security update, 4483452. These reports are specific to only to the scenario when a customer has installed both .NET Framework 4.8 Preview and the February security update.
We are actively working on fixing and re-shipping a correction for this issue. If you installed the February 2019 security update and have not yet seen any negative behavior, we recommend that you leave your system as-is but closely monitor them and ensure that you apply upcoming .NET Framework updates.
As a team, we regret that this release was shipped with this flaw. This release was tested using our regular and extensive testing process. We are working to improve our testing infrastructure to prevent these type of issues in the future. Again, we are sorry for any inconvenience that this product flaw has caused.
We will continue to update this post as we have new information.
