Windows 11's Hidden "Feature" That's Killing Performance - ofcource - 07-23-2024

If your Windows 11 machine feels sluggish even with top-notch hardware, you're not alone. There's a stealthy culprit lurking beneath the surface, but don't worry, I've got the lowdown and a solid fix.
The Problem: Memory Compression Gone Rogue
Windows 11 loves to compress inactive memory to free up resources. Sounds great in theory, right? The problem is, it can sometimes get a little overzealous, leading to a performance hit, especially on systems with lower RAM.
Symptoms You Might Notice:

Slowdowns when switching between apps
Stuttering during gaming or video playback
General sluggishness, even with simple tasks

The Fix: Take Back Control

Open Registry Editor: Hit

Code:
Win + R

Code:
regedit
, and press Enter (be careful, messing with the registry can cause issues if you're not sure what you're doing).
Navigate: Go to

Code:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Modify: Double-click the

value and change the data from

to
.
Reboot: Restart your computer for the change to take effect.

Bonus Tip: Monitor Compression
To see if compression is really causing your woes, keep an eye on the "Compressed memory" column in Task Manager's Performance tab. If it's constantly high, this fix should help.
Disclaimer: This tweak should be safe for most users, but as always, create a registry backup before making any changes, just in case.
