This PowerShell script is for initial setup after fresh installation of Windows 10 and partially Windows Server 2016/2019. The script is a set of tweaks for fine-tuning the OS and automating the routine tasks.
Read the code you run carefully. Some functions are presented as an example only. You must be aware of the meaning of the functions in the code. If you're not sure what the script does, do not run it.
The script was written for PowerShell 5.1 and for the current up-to-date version of Windows 10 Pro x64. Some of functions can be run also on LTSB/LTSC and on older versions of Windows and PowerShell (also on 32bit systems).
