[tpsize=4][tpb]= Block related Windows 10 upgrade and telemetry settings =[/tpb][/tpsize]

# Advantages:
- get use of latest Windows Update Client which solves the high CPU/Memory scan issue, and perhaps the slow/stuck scan issue
- seemingly make the related updates harmless (disabled), thus can safely enable Automatic Updates (as long as 'Recommended' updates option is off)
- do not need to keep track of future related updates, or if a new updates version released

# Disadvantages:
- no one would know what microsoft could come up with, so some blocking settings may get reverted by future updates
but you can always run/schedule the blocking script after any updating operation just in case

# Script:
copy the following and save as W10-Block.cmd
then right-click and select 'Run as administrator'

Note:
- some of the commands may return error (task or registry key not found), you can ignore that

# Schedule task:
to make sure the blocking settings are always set, you can create a schedule task to run the script at logon as example
1- copy W10-Block.cmd to C:\Windows directory
2- open command prompt as administrator and execute: 
[CODE]SCHTASKS /Create /F /RU "SYSTEM" /RL HIGHEST /SC ONLOGON /TN BlockW10 /TR "cmd /c %windir%\W10-Block.cmd"
SCHTASKS /Run /I /TN BlockW10[/CODE]
