Hey guy's now am posting a big relief from error
installing build from windows 10,8.1
when Microsoft download windows via store it save like install.esd which is a compressed file containing all required installation file. so now I am gonna tell how it's possible to extract files from it.please read all step carefully
Step One 
1.) Check if a new build is available. Tutorial: Preview Builds - Check for New Windows 10 Builds
2.) When a new build is available download it, install if you want to use it on the same computer. Installing is not necessary to create an ISO file as told in this tutorial, the files needed are available after downloading them
3.) The ESDtoISO tool is based on ESD Decrypter v.3, I have edited the original script to remove everything not necessarily needed. I will add one based on v.4 later. Download the tool (ESDtoISO.zip) from OneDrive: bit.ly/TenForums
4.) Open the downloaded ZIP archive with File Explorer, click Extract all, select where you want the files to be extracted, click Extract. Here I selected to extract the files on drive E:, folder ESD:
Step Two 1.) Copy the ESD file to same folder where you extracted the ESDtoISO tool files. Right click the ESDtoISO.CMD file and select Run as administrator. This runs the toll, automatically finding your ESD file.
-- OR --
Open an elevated command prompt and go to the folder where you extracted the ESDtoISO tool. Tip: this is easiest done by using the File menu in Explorer, simply open the folder where you extracted the files, click File > Open command prompt > Open command prompt as administrator:
2.) Copy the install.esd file from the folder C:\RecoveryImage to the same folder where you extracted the ESDtoISO files. Give the following command:
Code:
ESDtoISO install.esd
Notice please: the folder C:\RecoveryImage is the default location of Windows 10 TP install.esd file if you installed the upgrade. If you have moved the file in another location or you have downloaded the installation files but not upgraded yet or if the upgrade has failed, you'll might find the install.esd file in a hidden folder C:\$Windows.~BT\Sources.
You can also download both 32 and 64 bit ESD files from Microsoft in 20 languages.
3.) Select the ISO you want to create, a traditional ISO which contains the install.wim file to install Windows, or an ESD based ISO which instead of install.wim file contains the compressed install.esd to install Windows. Both types can be used the same way to install Windows, both can be used as such, mounted to a virtual drive or burned to Flash or DVD drive.
