How to achieve maximum performance in Windows 10 for a blind developer?

I can not post my post because of an error. Your post appears to contain code. Please, fix this!

Hello.

It’s good to have a beautiful operating system with a variety of visual effects, etc. Better yet, if productivity can be spent on something useful. Type of games, or specialized software. I'm a blind developer. I don't use graphics, and now I want to achieve maximum performance in Windows 10. Who climbed into the bowels of the monster, please help with tips on the best possible optimization.

My specifications:
Device: Dell Vostro 15 3568 Laptop
Processor: Intel Core i5-7200U
RAM: 8 GB
256 GB SSD
Video card: Intel HD Graphics 620

Installed operating system: Windows 10 LTSC 1809 (I don’t know if it makes sense to use Windows 10 Pro for me, not LTSC)

What was done (I translated all the items from Russian, for this reason, the names may not be same in the English version of the OS):
The latest drivers from Dell are installed;
The latest OS updates are installed;
Disabled everything in privacy;
In the control panel - System - Advanced system settings - Performance parameters are set to provide the best performance. Swap file disabled. Download and recovery has disabled the Display list of operating systems check box.
In the antivirus settings, I turned off Real-time Protection, Cloud Protection, Automatic Sending of Samples.
Further in gpedit.msc - Computer Configuration - Administrative Templates - Windows Components - Windows Defender antivirus program has enabled the Turn off Windows Defender antivirus program policy. Disabled the Allow permanent anti-malware service policy.
In the Real-time protection branch, I enabled the Disable real-time protection policy, disabled the Scan all downloaded files and attachments policy.
In the MAPS branch, disabled everything, turned on Send sample files if further analysis is required, and indicated Never send.
In the CMD, from the administrator, I executed:
gpupdate
sc delete DiagTrack
My friend advised the scheduler - Microsoft - Windows - Application Experience to delete all tasks.
Disabled disk indexing.
In secpol.msc - Local Policies - Security Settings has disabled the User Account Control policy: all administrators work in administrator approval mode.
Disable hibernation via powercfg –h off.
I tried to knock out the Xbox Game DVR through execution in PowerShell Get-AppxPackage * xbox * | Remove-AppxPackage, but got an error:
Remove-AppxPackage: Deployment failed with HRESULT: 0x80073CFA, Uninstallation failed. Contact your software vendor
providing. (Exception from HRESULT: 0x80073CFA)

In Power Supply exhibited High performance.

Xbox Live Network Service
Network login
Geographic Location Service;
Windows Image Download Service (WIA);

Windows Update

I have an SSD. Given this, I do the following.
Disabled the Windows indexing system;
Disabled creating the Layout.ini file;
Disabled Superfetch and Prefetcher;
Disabled defragmentation of system files at boot.

How true are my actions? What should I not do from this, what should be added to this?

My ultimate goal is to maximize the performance of Windows 10.

Thanks in advance!
