I have installed security hotfixes. How do I ensure that my system is protected from any potential security problems?
You should run QFECHECK.EXE and follow the guidance it provides. The tool will tell you whether your system is safe as it is, or whether you need to reinstall one or more hotfixes, or whether you should install the catalog-only hotfix that is listed in the security bulletin. Once you have run QFECHECK.EXE and followed the guidance it provides, you needn’t worry further about this issue.
