The virus protection integrated into Windows 10 and Windows 11 is intended to slow down Intel CPUs in particular.
Windows Defender can slow down Intel CPUs with a bug.
If you operate a computer with Windows 10 or Windows 11, you can protect yourself against malware and viruses with the preinstalled Windows Defender. This protection can definitely keep up with the paid competitors. However, if an Intel CPU is also installed in the computer, the Defender can slow it down. This is the conclusion reached by software developer Kevin Glynn. A bug is said to make Intel CPUs from the ninth generation work slower under both Windows 10 and Windows 11.
Six percent less performance
The performance loss for an Intel Core i9-10850K is said to be six percent in Cinebench. Due to an error, Windows Defender keeps turning on and switches to the wrong mode. The software developer advises installing Throttle Stop 9.5, which he developed. Inside is a feature called Windows Defender Boost that is supposed to fix the problem. Alternatively, the real-time protection of the Defender can be deactivated. However, this comes with significant security risks.
Update must fix problem
AMD processors are not affected by the bug. Now it is up to Microsoft to remove the error in Windows Defender. When Microsoft will provide such an update remains open. It is also questionable to what extent the bug will have an effect in everyday use or when playing games. In the case of the Cinebench benchmark, however, the error costs some performance. Intel should therefore also be interested in a solution, after all the benchmark results serve as a rough guide for many buyers.
