Just a small bug. The script isn't deleting the temp files 'OfflineTemp_1169653747' folder in the Optimize Offline folder when the script exits.

Made me curious and checked it out: sorry, but that's inaccurate, mine is not the same with that old unsafe code prone to memory leaks and race conditions

to integrate mine in ps1 scripts, just define the function somewhere:

Code:

function :DIR2ISO ($dir, $iso) { if (!(test-path -Path $dir -pathtype Container)) {"[ERR] $dir\ :DIR2ISO";exit 1}; $dir2iso=@"
 using System; using System.IO; using System.Runtime.Interop`Services; using System.Runtime.Interop`Services.ComTypes;
 public class dir2iso {public int AveYo=2021; [Dll`Import("shlwapi",CharSet=CharSet.Unicode,PreserveSig=false)]
 internal static extern void SHCreateStreamOnFileEx(string f,uint m,uint d,bool b,IStream r,out IStream s);
 public static void Create(string file, ref object obj, int bs, int tb) { IStream dir=(IStream)obj, iso;
 try {SHCreateStreamOnFileEx(file,0x1001,0x80,true,null,out iso);} catch(Exception e) {Console.WriteLine(e.Message); return;}
 int d=tb>1024 ? 1024 : 1, pad=tb%d, block=bs*d, total=(tb-pad)/d, c=total>100 ? total/100 : total, i=1, MB=(bs/1024)*tb/1024;
 Console.Write("{0,3}%  {1}MB {2}  :DIR2ISO",0,MB,file); if (pad > 0) dir.CopyTo(iso, pad * block, Int`Ptr.Zero, Int`Ptr.Zero);
 while (total-- > 0) {dir.CopyTo(iso, block, Int`Ptr.Zero, Int`Ptr.Zero); if (total % c == 0) {Console.Write("\r{0,3}%",i++);}}
 iso.Commit(0); Console.WriteLine("\r{0,3}%  {1}MB {2}  :DIR2ISO", 100, MB, file); } }
"@; & { $cs=new-object CodeDom.Compiler.CompilerParameters; $cs.GenerateInMemory=1 #,# no`warnings
 $compile=(new-object Microsoft.CSharp.CSharpCodeProvider).CompileAssemblyFromSource($cs, $dir2iso)
 $BOOT=@(); $bootable=0; $mbr_efi=@(0,0xEF); $images=@('boot\etfsboot.com','efi\microsoft\boot\efisys.bin') #,# efisys_noprompt
 0,1|% { $bootimage=join-path $dir -child $images[$_]; if (test-path -Path $bootimage -pathtype Leaf) {
 $bin=new-object -ComObject ADODB.Stream; $bin.Open(); $bin.Type=1; $bin.LoadFromFile($bootimage)
 $opt=new-object -ComObject IMAPI2FS.BootOptions; $opt.AssignBootImage($bin.psobject.BaseObject); $opt.Manufacturer='Microsoft'
 $opt.PlatformId=$mbr_efi[$_]; $opt.Emulation=0; $bootable=1; $BOOT += $opt.psobject.BaseObject } }
 $fsi=new-object -ComObject IMAPI2FS.MsftFileSystemImage; $fsi.FileSystemsToCreate=4; $fsi.FreeMediaBlocks=0
 if ($bootable) {$fsi.BootImageOptionsArray=$BOOT}; $CONTENT=$fsi.Root; $CONTENT.AddTree($dir,$false); $fsi.VolumeName='DVD_ROM'
 $obj=$fsi.CreateResultImage(); [dir2iso]::Create($iso,[ref]$obj.ImageStream,$obj.BlockSize,$obj.TotalBlocks) };[GC]::Collect()
} $:DIR2ISO: #,# export directory as (bootable) udf iso - lean and mean snippet by AveYo, 2021

and then call it like this:

Code:

:DIR2ISO "ISOFOLDER" "folder.iso"

Yes i know that one and it happens with ISO source. Will try to resolve it.

Does anyone know how to integrate PowerShell 7 into an install.wim or our Windows ISO?

Yes using msmg pack powershell7 tpk plus its offline registry via dism commandlet.

You have a link or anything on what exactly to do?

Edit: I think MSMG Toolkit does it.

Just throwing this out there if it hasn't been said before. If you remove the HTML Edge stuff, while it may seem fine and stuff does work, various things will act wrong. For instance, some settings about pages and whatnot will inform you that the removed Edge component is missing and in programs like Discord, URLs will always ask you which browser you want to open, even if you select the always open with option. This issue has occurred on both 1909 and 21H1 ISOs and I've finally isolated it.

I've updated my post #992 - "Resources to help design APPX remove/keep lists aka Blacklist/Whitelist" with some more details after finding a very nice System Apps Inventory script

How exactly do you edit the script to add that line?

I tried both first lines of Start-Optimize.ps1 and Optimize-Offline.psm1 and it errors out.

Have you tried manually pasting it into the terminal after all the code completes?
I know that's not ideal, but it's the only way I've successfully tried it so far.

The quote about adding it to a script was from someone on the original source page.

I've not had much success writing (or editing) scripts lately, for the time being I'll just bring these potential "treasures" here and hope better minds can make them work
