Microsoft has implemented this Memory Integrity feature since Version 1803 in Windows 10 and it is standard in Windows 11. Its purpose provides isolation to Windows processes running in memory to guard against malware attacks. Look at it as additional layering protection under your anti-virus program. A simpler explanation would be when you drive up to one of our access gates you are allowed entry if you have a validated window sticker or access card. Applying the Windows technology, you are treated as potential malware until you are verified by the gate’s security reader. Once in and home, you are isolated from other things going on outside. It’s the same way for other Window’s processes running at the same time.
However, as nice as this sounds, it comes at a cost. A possible significant cost in your computer’s speed. I’ve experienced up to a 30% decrease in boot speed when I do a restart. Windows does have a Fast Startup feature that is on by default which reduces boot time from a power on start.
Since there are many variables involved, you can try this easy test to see if it is worth it to turn off Memory Integrity or to leave it on. On Windows 11, to access it, click Settings, click Privacy & Security, click Windows Security, click Device Security, click Core Isolation Details and turn off Memory Integrity. Windows 10 versions may have a slightly different path. Restart the computer and then try opening several different programs one at a time to see if the response is faster. Try restarting it to see if it boots faster. If you don’t see much change just follow the previous instructions and turn Memory Integrity back on. Wait until it checks your computer then restart it. If you decide it works better with Memory Integrity turned off, you may see a yellow badge on the Windows Security icon on the Taskbar near the clock or click the little up arrow to see it. All that means is that it is notifying you the Memory Integrity is turned off. Go back to Memory Integrity and click Dismiss.
NOTE: To evaluate this test properly, make sure you restart the computer when turning Memory Integrity off or on. Do not shut down the computer as it will invalidate the results.
