Teguar’s Response to Spectre and Meltdown

Teguar Computers is aware that the recent computer security issues uncovered with the Spectre and Meltdown vulnerabilities affect many of our products sold. These vulnerabilities are inherent with several Intel, AMD, and ARM CPUs. Bios and firmware changes are being made for current Teguar Computer hardware orders in process to negate any issues from Spectre or Meltdown. If you have further questions please contact support@teguar.com

The first step that our customers can take to mitigate these issues are the security patches released by Microsoft. If automatic update is running on your PCs, then you do not need to take any action and you most likely already have the patch. Here are direct links to the patches that you can download to ensure you are protected.

If you are unsure of the exact version of OS installed, you can try to install all patches (starting at the top) as the patch will not run if it is not meant for your OS. You can also open up the start menu and type “winver” and press enter. This will display your OS version.

Teguar will also be implementing BIOS level microcode patches as they become available from Intel and are validated on our hardware. These patches will be included on new product shipments. Below is a list of our computers that may be affected:
