Spectre

How can I get my Windows computer to update?

Blue screen of death

Episode 1458

Rene from Corona, CA

Rene is having trouble updating Windows. It stalls out at 80%. He then reboots and it goes back to before he tried updating. Then he gets a blue screen and he can't restore or update. Leo says that not an unusual problem. If you think about it, with millions of computers, there's going to be a certain percentage that will experience issues like this, and updating while a computer is running is nontrivial. It could be something is blocking it, like a third-party antivirus app. It could also just be a bad download. Or this could be the Intel Spectre/Meltdown fix that is causing problems.

Spectre and Meltdown Flaws Continue To Plague Intel

Episode 1457

With the now infamous Spectre and Meltdown processor flaws affecting every intel based computer for the last ten years, Intel pushed out a fast fix to plug the holes. Now they're saying not to use it. It seems that some computers will get stuck in a reboot loop. So the cure is worse than the disease. To date, there's been no evidence that the Spectre and Meltdown flaws have been exploited, so Leo is wondering if the right advice is to do nothing at all. At least until a new fix has been released, or that malware shows up that will take advantage of it.

Should I install the Spectre bug fix?

Irwin from The Bronx

Irwin is concerned that the Spectre bug fix will slow down his computer. Leo says it's possible, but it's unlikely to have a noticeable impact on a modern machine. Experts say the bug fix will greatly affect slower, older machines. A newer machine will get the least performance hit. He should just make sure to update his AVS and all of his drivers.

VMware or really heavy applications are where the performance hit will most likely be affected.

Why can't I download the Meltdown fix for Windows?

Windows Update

Episode 1453

Travis from Oklahoma

Travis is having trouble getting the Windows update that will fix the Meltdown/Spectre exploit. Leo says he should make sure to update his antivirus first, because the fix will break the AVS and crash the machine, forcing a reinstall of the OS. He may also need to do a BIOS update. In fact, the entire machine may need to be updated to prevent the Windows OS update from breaking the machine.
