So we have recently had issues with the KB971033 update within our network and i have managed to get a working script for removing it and reactivating windows, however when trying to get a detection script working to assure it only runs on effected computers i cant get it to correctly output true or false when testing against installed KBs. 

So far this is what im running. No matter what i do it will output false. Anything obvious i am missing?

```
if ((get-hotfix).hotfixid -eq "KB971033") {$true} else {$false}

```
