• Microsoft has started to push out a fix for a widely-reported security vulnerability in Intel, AMD, and ARM processors, reports The Verge.
  • The fix started to go out to Windows 10 users Wednesday. Microsoft will release patches for Windows 7 and Windows 8 on Tuesday.
  • The patches will cause some PCs to take a hit to their performance.
  • Windows PCs with Intel’s “Skylake” processor family will be the least affected, but older PCs could reportedly see a noticeable drop in their performance.

The processor security flaw that has the tech world abuzz is already being fixed for Windows computers — but the fix doesn’t completely solve the problem, and right now it’s only available for those running the latest version of the operating system.

The security flaw affects Intel, AMD, and ARM processors. It’s been widely reported that fixing it could require most PCs to take a sizable performance hit.

Microsoft started to push out a patch for the vulnerability for Windows 10 computers on Wednesday afternoon. It plans to release fixes for Windows 7 and Windows 8 on Tuesday, according to The Verge.

But those patches for Windows are only half the battle. Processor manufacturers will have to release their own updates to completely plug the security flaw. For its part, Intel expects to start releasing its patches next week, company CEO Brian Krzanich said on CNBC Wednesday afternoon.

The fixes for the vulnerability will have different effects on PCs, depending on the vintage of their processors. PCs with processors based on Intel’s two-and-a-half-year-old Skylake architecture or newer won’t see a “significant” performance reduction, The Verge reported, citing sources familiar with Microsoft’s thinking. But PCs with older processors could see a noticeable slowdown in their processor speeds.
