How to speed up windows 11 and make it run faster?

Disabling Memory Compression in Windows 11 can potentially speed up Windows 11 in certain scenarios, especially on systems with limited RAM or specific workloads. However, it may also lead to increased disk activity and reduced efficiency in managing memory.

Memory Compression is a feature in Windows that compresses unused or less frequently used pages in RAM to reduce the need to access the disk (paging). This helps speed up Windows 11 and overall performance by making better use of available RAM.

Pros of Disabling Memory Compression:  
May reduce CPU overhead associated with compressing and decompressing memory pages.
Can free up CPU resources for other tasks in certain cases.
Might improve performance on very specific workloads or hardware configurations.

How to Disable Memory Compression:
Disabling memory compression requires registry edits or command-line tools. Here’s a common method using PowerShell:
1. Open PowerShell as Administrator.
2. Run the following command to disable memory compression:

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" -Name "Compression" -Value 0

3. Reboot your system.
Note: Always back up your registry before making changes, and be cautious as improper modifications can cause system instability.
