Optimize-Offline Guide - Windows Debloating Tool, Windows 1803, 1903, 19H2, 1909, 20H1 and LTSC 2019

You have my approval!

 

I made new tests and can confirm that the problem is repeatable.

I used VM under Virtualbox 6.0.14 and original ISO of Windows 10 1909 from Microsoft. I created a new VM with this ISO and everything is OK. It boots in BIOS mode.
In this VM I used Optimize-Offline tool 3.2.7.8 and made a new ISO with only 1 WinApp removed. This second ISO DO NOT BOOT in Virtualbox in BIOS mode, but in UEFI it boots.
Also, when I extract the new ISO with 7-ZIP, it displays a warning that there is data after the payload. This message DOES NOT emerge with the original Microsoft ISO.

The log files are clean, with 0 errors. I think there are some circumstances in the ISO creation, that are not dealth with by the best way. Maybe something with the Windows API?

Not exists any options for exclude the dart integration

 

Edit the bottom of Start-Optimize.ps1 with your required paramaters
Mine (Used with 19033):

Code:

Else
{
   Optimize-Offline -SourcePath "D:\19033.1000\sources\install.wim" -WindowsApps "Whitelist" -SystemApps -Capabilities -Packages -Features -Registry -Additional
}

The above, Outputs (in my case) this Configuration.json Template at the end of the optimization, for future use

Spoiler

{
"_Info": [
"This is a JSON based Configuration file for Optimize-Offline.",
"Ensure proper formatting is used when editing the JSON parameter values.",
"Boolean parameter values use true and false. String parameter values must be enclosed in double-quotes."
],
"SourcePath": "D:\\19033.1000\\sources\\install.wim",
"WindowsApps": "Whitelist",
"SystemApps": true,
"Capabilities": true,
"Packages": true,
"Features": true,
"DeveloperMode": ,
"WindowsStore": ,
"MicrosoftEdge": ,
"Win32Calc": ,
"Dedup": ,
"Registry": true,
"Additional": true
}

Hope this helps...

What does it mean ? - Optimize-Offline now requires a system culture of en-US. - doesn't work if iso is pl-pl ?
I do not understand English well.

 

Jumped the gun
.. looking in to this further, it seems there may be some issues

JSON Template (Output by Optmize Offline Script)

Code:

{
  "_Info": [
    "This is a JSON based Configuration file for Optimize-Offline.",
    "Ensure proper formatting is used when editing the JSON parameter values.",
    "Boolean parameter values use true and false. String parameter values must be enclosed in double-quotes."
  ],
  "SourcePath": "D:\\19035.1000\\sources\\install.wim",
  "WindowsApps": "Whitelist",
  "SystemApps": true,
  "Capabilities": true,
  "Packages": true,
  "Features": true,
  "DeveloperMode": ,
  "WindowsStore": ,
  "MicrosoftEdge": ,
  "Win32Calc": ,
  "Dedup": ,
  "Registry": true,
  "Additional": true
}

(1) Parameters set are more than 2
line 56 # If the ordered collection list has a key count less than two, terminate the script. Else call Optimize-Offline passing all of our set parameters to it.
line 57 If ($ConfigParams.Count -lt 2) <-- If 2 is used script terminates with following error

PS D:\Optimize-Offline-4.0.0.0> .\Start-Optimize.ps1
ConvertFrom-Json : Invalid JSON primitive: .

(2)
line 57 If ($ConfigParams.Count -lt 2) <-- If 2 is changed to 0 it will run the script with the following parameters (Completing without any errors)

line 63 Else
line 64 {
line 65 Optimize-Offline -SourcePath "D:\19035.1000\sources\install.wim" -WindowsApps "Whitelist" -SystemApps -Capabilities -Packages -Features -Registry -Additional

.. and the subsequent .json template (reproduced above) confims the parameters are as stated.

However on closer inspestion it is clearly apparent that the -Additional switch (Setup, Additional Registry Tweaks) is not implemented nor applied to the image

... am I missing something

 

.. not the case (don't actually code myself), JSON used was one created by the script itself
also, "Additional" being the last parameter of the set, should not require a comma after it
but just to be sure, ran script with comma - no difference, same issue -> fails at line 40 with Invalid JSON primitive

but as previously stated, I bypass the issue by changing line 57 $ConfigParams.Count -lt from 2 to 0.
Script runs but does not apply the "Additional" parameter

@Kedar Wolf
apart from our different requirements (ie. have no use for ISO, so it is omitted), there are no differences
- same script, and valid json files (Configuration/Additional). However, on running (in my case) the Start-Optimize.ps1 script fails
ConvertFrom-Json : Invalid JSON primitive: . suggesting that a DOT (.) there is the issue
At D:\Optimize-Offline-4.0.0.0\Start-Optimize.ps1:40 char:32 (Line 40 Character 32, which is nothing but a space)

but as I said I don't code and can't fathom at the moment what the problem is

Script has been run with JSON formatted both ways
using "WindowsStore": false, or "WindowsStore": ,
.... but to no avail. Will continue to investigate further ... entertaining

Edit: with a bit of luck Godhand may be monitoring and may be able to shed some light

 

I can confirm, that there is an issue somewhere in the parameters section, because when I ran the script with only "windowsApp" and/or "SystemApp" parameters, besides "ISO" and "SourcePath", not every time the windows for selecting apps for removal appear. The "WindowsApp" is set to "Select", but it does not show every time.

Which parameters are counted in the above mentioned number 2?

I also hope that the GUI version will be more stable.

 

i love this s**t when you do all the steps believing will work like is working to the others and in the end dosent work.

 

You need to add false to each item that you don't want in your Configuration.json. They shouldn't be left blank.

Code:

{
  "_Info": [
    "This is a JSON based Configuration file for Optimize-Offline.",
    "Ensure proper formatting is used when editing the JSON parameter values.",
    "Boolean parameter values use true and false. String parameter values must be enclosed in double-quotes."
  ],
  "SourcePath": "D:\\19035.1000\\sources\\install.wim",
  "WindowsApps": "Whitelist",
  "SystemApps": true,
  "Capabilities": true,
  "Packages": true,
  "Features": true,
  "DeveloperMode": false,
  "WindowsStore": false,
  "MicrosoftEdge": false,
  "Win32Calc": false,
  "Dedup": false,
  "Registry": true,
  "Additional": true
}
