When i try to fetch "KB4571703" (August security monthly rollup for 2012 R2) using Get-hotfix command OR even checking installed updated in add/remove programs, i don't see this is installed, However it was successfully installed last month and same can be viewed in "view update history" in windows update (wuapp)
Note: this patch (KB4571703) is not removed explicitly by any administrator also "KB4577066" (September security monthly rollup for 2012 R2) was installed in this month
Now when i try to run standalone of August patch it stats "this is patch is not applicable" which is obvious considering September rollup is already available on server
But, what wonders me the most why result of Get-hotfix KB4571703 returns patch was not found on the system.. Does anyone have any explanation to this...
