Hey! .
Im Fandrall and i will teach you how to speedup your PC to play decently DO.
FIRST and most important:
Download WINDOWS ENTERPRISE VERSION, not pro, not home.
LTSB or LTSC.
We need delete services, to put CPU,RAM and disk in a low usage.
So enterprise version haven't pre-installed oop: services and merchandising things.
Search for an iso on google and install it.
Please, be sure of choose correct version of windows according to your hardware .
Use google => Search for "CPU release date" (Change CPU per your cpu, ofc.
Then if you pc are from 2012-2016 => Use 1607 version of windows.
For more versions, then search in google as "windows 10 release dates of distros" then determine which version of W10 you need to use.
This is very important, because microsoft launch updates and makes the old hardware worse!!!
Example: My old laptop was with windows 1907 and was trying to transfer things into a usb 3.0 , then 9 or 10 mbps as transfer speed.
I put w10 ltsb (1607) and then 120 / 130mbps.
You can look for "Windows 10 MiniOs version" too.
Then:
1. Install W10
2. Win+R => sysdm.cpl => Enter
2.1 Advanced => Performance => For better performance => Advanced (again) => Virtual memory => Change => If you have an SSD disable it to make your SSD durable , if you have a HDD => Custom Size => Minimum (RAM x 1.5), i have 4gb so 4096 so 4096x5 = X, MAX= RAM x 3
2.2 Install MS redistributable, look for a pack which have all versions in one file in google
2.3 Disable windows animations, themes, etc
2.4 DISABLE WINDOWS UPDATE.
2.5 DON'T USE MSCONFIG TO ENABLE ALL CPU CORES.
Use Chrome Enterprise if you can, MSEdge, Opera GX or Maxthon for play DO.
I prefeer edge cuz need less ram and cpu.
Note: If LTSB / LTSC versions don't work fine for you try:
A) Install Windows media feature pack (look it on google)
B) Try another tipe of windows version like home
