Windows 10: ESD folder on disk C

Hello!
I am new here so please excuse me if this is already answered.
I am succesfuly upgraded Windows 8.1 Pro 64 bit to Windows 10 Pro 64 bit via Microsoft Free Upgrade offer.
Everything works fine, so there is no problem

My question is:

After upgrading to W10 there is on disk C folder named ESD with subfolder named Windows(just Windows, without version number) - its about 3.4 GB
Content of this subfolder(Windows) is:

Folders:

boot
efi
sources
support

and files:

autorun.inf
bootmgr
bootmgr.efi
setup.exe

It looks like a files and folders on bootable USB or DVD

For what is this usable and how to use this?

Thanks for answers *Wink

What is ESD Folder?

Hi,

There is one folder on my PC called "ESD", which is at This PC > Local Disk (C > ESD location. It is empty folder now. If it is not important I want to delete it.

Can you explain what it's exact name and what it does?

 

Windows 10 create your own installation media

You will need to decrypt the Windows 10 ESD file which is located w/in the following folder

C:\$Windows.~BT\Sources\Install.esd

upon your hard disk & convert it from an esd file back in to an ISO file using an ESD to ISO decrypter for your Windows 10 installation which can be saved to a safe place upon your PC!

There should be a file called "install.esd" in Sources sub folder. It could be used to make an ISO to keep as backup to make a bootable USB/DVD so you can do clean install of W10 or use as repair disk. Saves you from having to download W10 again to use like that.
You can use ESD to ISO - Create Bootable ISO from Windows 10 ESD File - Windows 10 Forums to do that.
Afterwards you can remove all of that (including Windows.old) using "Disk cleanup" as you will not need it any more if you don't plan to revert to previous windows.

 

You can make an ISO out of that folder to create a windows setup media iso....

or copy the contents of that folder to a fat32 formatted USB stick to make windows setup media...

I went from W7 to W10 a year-and-a-half ago. I guess the "Windows ESD installation files" thing has been there the whole time, 3.04 GB. The description for these files says something about "refresh" and "reset."

If I wanted to go back to W7, I could use the W7 system image I created before switching to W10. Also, if I had a problem with W10 I have the installation disk, plus I create a system image every week.

It seems safe to delete this thing, but can anybody tell me under what circumstances these files would be used, and how; would I do something, or the "system?" Thanks.

 

They can be safely removed..
