Windows 7: Suggestions or Tutorials to reduce custom install.wim size?

Suggestions or Tutorials to reduce custom install.wim size?

Hi SevenForums!

I'm an avid fan here and many utilities I've used are from here!

Seriously speaking, you guys are a one stop centre for any computer needs!

Anyways, let me come back to the point of my thread.


So I'm currently trying to develop a customized Windows 7 Enterprise installation with SP1 and some applications installed.

I've used some cleanup utilities to clean temp files and stuffs from the installation before sysprep-ing it with generalize option.

The size of the install.wim that is created is just a lil' larger than needed to fit a DVD-R.

I'm not into using DVD-R DLs as of now.

Currently, the size is about 4.5GB and I'm trying to fit it into a DVD-R that is 4.38GB.

Any suggestions or stuffs that you guys can advice me on?

Is there any way I can compress it any further?

BTW, I'm going to be needing ONLY Windows 7 ENT 32BIT. (if this information helps!)

Are you using imagex /compress maximum?

If you are then other than removing components I don't know of any other way. I think RT Seven Lite will remove the components as well as their files.

Hi and thanks for the response.

Basically what I did to prepare the image was:
1. CCleaner (Enhanced Version)
2. Temp files cleaner (Hiren)
3. System Ninja
4. ATF Cleaner

After all this, i proceeded to created the image with generalize ticked.

On creating the install.wim, i used maximum compression.

If I were to remove components what are the recommended components that can be removed?

(Image is for a school where everyone owns a laptop configured with this Windows 7 ENT)

Personally I wouldn't recommend removing any components, but if I had to I would remove components that I would not use. How much space can you save without removing useful features is another question I could not answer.

Really I would just use a DL DVD-R or use a 8GB or bigger USB stick.

Noted with thanks.

I guess my only feasible solution would be to utilize a DVD DL.

Thanks! :)

Sorry I couldn't be of better help but I did think of one more cleanup option. It's possible that the cleanup progams you have already run have already cleaned everything but you could try the built-in Windows disk cleaner but run it from the start menu as

cleanmgr /sageset:1 - sets what to clean
cleanmgr /sagerun:1 - runs it with the options you set

Running it this way gives a few more options although on a clean install those extra option probably won't help much but it's worth a try.

Sorry for the late reply.

Yep I did that too!

But here's my final iso:
Win7 ENT x64x86 - Slipstreamed SP1

Time to get some DVD-DLs are try them out! Worked perfectly on VM.
