An attacker could then install programs; view, change, or delete data; or create new accounts.Supported Operating Systems

The Exchange Server SETUP program will specify any required components that are missing- We recommend restarting your computer before installing a security update. Then follow these steps:
- Disable the anti-virus software.
- Open an elevated Command Prompt window (not PowerShell) as an administrator, like this:
- Select Start and then enter cmd .
- Right-click Command Prompt in the results and select Run as administrator .
- If the User Account Control dialog box appears, select Yes and then Next .
- At the command prompt, enter the full path to the folder that contains the 'MSP file', then press 'Enter'.
Note: Do not double-click the 'MSP file' to run it. - When the installation is complete, re-enable the antivirus software and restart your computer. (The installation program may prompt you to restart.)
If problems occur during or after this installation, please refer to Repair failed installations of Exchange Cumulative and Security updates before contacting Microsoft Support.
