Known Issues and Limitations

- Intel SGX only supports the integrated Windows authentication proxy scheme. The Basic and the Digest authenticated proxy schemes are not supported.
- You cannot load any enclave in Windows 7/8.1 if the Microsoft Universal C Runtime (CRT) is not installed on the system. To resolve this issue, you can install the Windows Update for the Universal CRT (KB2999226) on Windows.
- You cannot install the Intel SGX PSW when you install Windows OS in a legacy mode and the Intel SGX is set as “Software Controlled” in BIOS. Configure the Intel SGX as “Enabled” in BIOS before you install the Intel SGX PSW.
- Legacy (before 1.6 version) Intel SGX PSW installation entry cannot be removed from “Programs and Features” in the Windows Control Panel if you install the legacy Intel SGX PSW and upgrade it with a new installer (after 1.7 version). To resolve the issue, manually uninstall the Intel SGX PSW before installing a new version.
- Intel SGX PSW .exe installer returns an error if a higher version of the Intel SGX PSW installer is already installed.
- Applications that use the Intel SGX PSW in Microsoft Windows 10 Version 1709/1803/1809 and do not have proxy settings for their users, require a system proxy setting. Alternatively, the Intel SGX AESM proxy configuration tool can be used.
- After installing the Intel SGX PSW .inf installer, the Intel SGX AESM service status is set to “stopped”. It does not impact enclave loading by the Intel SGX application. When the enclave is loaded, the Intel SGX AESM service status is set to “running”.
- Installation of the Intel SGX PSW .inf installer has no impact on the Intel SGX PSW .exe installer of version 1.7 but it can affect the Intel SGX PSW .exe installer of version 1.8 or higher.
- User can’t verify Intel ECDSA QE’s report outputted from sgx_get_quote_ex() function when user installs Intel Quote Provider Library and Intel Platform Certificate Service (PCS) Cache Server installer.

About Tuning Utility:

Install this tuning utility and you will be able to manually configure various overclocking values, such as CPU and memory frequencies, system clocks, fan speeds, and monitor temperature for different components.

However, please note that you're supposed to tweak these settings only between supported ranges; changing configurations to extreme values without additional cooling systems might seriously damage components.

The installation steps needed for the software to be applied are very easy: get the downloadable package, extract it if necessary, run the available setup, and carefully follow all displayed instructions for a complete and successful installation.

In addition to that, please note that it's recommended you perform a system reboot so that all changes can take effect properly. Bear in mind that, even though other OSes might be compatible, we don't suggest against installing this release on platforms other than the highlighted ones.

That being said, click the download button, get the package and set up this feature on your system. For more on the latest releases, keep checking back with our website to “stay updated one minute ago.”
