This is appreciated very much:oops:
Thanks, if you find that a component is needed for a program or hardware, let me know and i'll add it.

I need to make sure that there is not a bug.

I'll update today with CEIP and Windows Error Reporting.

Nice list. Is there a way to import this as a Compatibility check box?

The only item I might question is keeping SMBv1. I know it breaks NetBIOS/NetBeui when one removes it. But it's a known vulnerability for malware (the Wanna Cry?). Even before that, M$ was suggesting the ppl disable it. See https://blogs.technet.microsoft.com/filecab/2016/09/16/stop-using-smb1/

If I have it right, when SMBv1 is removed, users have to use TCP/IP for home network sharing instead of NetBios.

Windows Media Codec "may" be needed by some audio editors/DAWs/media players. Sound Forge complains if codecs have been removed but it still installs.

You might find those video edit programs may fail during installation. I havnt seen it yet.

I need to check which one but a sony program fails if .net3x if not present, it will try to download it, if it cant, no instally. I need to check some .net and c++ requirements, will let you know my findings.

Kasual. Found some service dependencies. Export System Packages by knarz wont run if Network Store Interface Service and Workstation are disabled, stopped. :)
That would be good for another thread for services, something like "Stop/disable Services: trouble free"

Note - Remote and Privacy. CEIP (SQM).- Could be needed for Battle.net app (from blizzard).
Test by disabling CEIP and CEIP and related scheduled tasks.

I have never used the " CEIP (SQM).- " I use battle.net and play Overwatch and tried Diablo but havent found any error yet.
I allso used Emma's Barbone present long time ago without any error :O
"W7-Installwim-Barebone-v3" - "w7-barebone+networking-v2"

Edit: It can be that I use some windows update that I dont get any error.

I just did a refresh of my Win7 desktop using my previous Preset with "add backs" from your work.

Specifically, I added back MDAC because of Task Scheduler. (As I write this, I should probably have added back Dist Link Tracking Client because I use a Registry Hack to remove Libraries, and sometimes that hack causes problems.)

Anyway, my latest refresh seems to be working better than my previous build.

That has me wondering: If MDAC is needed for Task Manager, than perhaps it should be moved to Recommended? As it is now, it is only preserved if one has "Office" enabled for compatibility.

Enhanced Video Renderer - EVR. MPC HC includes "MadVR". Source. EVR maybe safe to remove.

MPC HC maybe discontinued. Source. MPC BE(Black Edition) appears to be active.

MPC HC includes MadVR but MPC BE doesnt not, you need to download it seperately.

I just tried the Search feature in WMC. In an earlier build of Win7, where I had removed MDAC, the Search feature crashed WMC after I entered more than two characters. Now, with MDAC, the Search feature works fine.

Can't say for sure that MDAC was the only variable that changed, because I used a newer version of NTLite (1.) to make this build; I didn't do any cleanup until Live; and I integrated one more KB at the beginning of the build. And also, WSUSOffline Updater added only 44 updates where it previously added 48.

I suppose I could remove MDAC via Live and report back to see if that breaks WMC. But I'm having too much success now to mess with a good thing. (Maybe I'll try later.)

Windows Media Player and Codecs are probably only needed for WMA and WMV because they are MS patented codecs, not sure about WAV though. Probably only needed on higher end programs, Audacity REAPER Wavosaur VLC(all run portable) all have enough built in codecs or need LAME and FFMPEG and those 4 run on w7 bareboned with windows media player and codecs removed, I only kept EVR for VLC. Thats running on Realteks onboard audio, dont know about usb audio interfaces though, sods law says their software needs .nets or c++'s. Fraunhofer MP3 patent has now expired.

Kas, you mentioned this before. It may be possible to fool those programs into thinking wmp is installed by just manually removing folders and leaving their registry info alone.

It wasn't me, otherwise, i would say files and reg info, not only folders because most of the times, files are scanned, i think pmikep found out that keeping iexplore.exe could solve an issue.

I tried keeping Windows Media Player files for Smart Switch, starting with WMV codecs but after i dropped back about 4 dll's requested by Smart Switch setup, i stopped and decided to keep WMP.

W7 Pro N doesnt have evr.dll and is about 600mb smaller than non N version. It should be possible to add evr.dll files to N version, i dont know if they will need to be registered or not.

Its in Microsoft-Media-Foundation-Package-amd64-6.1.7601.17514 or just copy from a non N install.
C:\Windows\System32 and C:\Windows\SysWOW64

The same will probably be true for w8/8.1 and w10 N versions. Possibly for the KN(Korean N), cannot confirm though.

Try adding the media feature pack and search for evr.dll. If there is evr.dll, there is no need to do anything else.
