Update to Disable Mitigation against Spectre, Variant 2. You know, for when your update was not really an update but rather a downdate, which might be referred to as the poopshow….to say it nicely. Anyway, this should roll back the Intel patch that was causing reboots if you have it impacting any important boxes. Applies to: Windows 7 Service Pack 1Windows 8.1Windows 10 and more.


Intel has reported issues with recently released microcode meant to address Spectre variant 2 (CVE 2017-5715 Branch Target Injection) – specifically Intel noted that this microcode can cause “higher than expected reboots and other unpredictable system behavior” and then noted that situations like this may result in “data loss or corruption.” Our own experience is that system instability can in some circumstances cause data loss or corruption. On January 22nd Intel recommended that customers stop deploying the current microcode version on impacted processors while they perform additional testing on the updated solution. We understand that Intel is continuing to investigate the potential impact of the current microcode version and encourage customers to review their guidance on an ongoing basis to inform their decisions.
