Windows 10: Verify the integrity of these files

Hello,

I was sent an .iso file by our co-worker to install on a computer. I've got the file by e-mail.

The .iso file is for Windows 10 Enterprise LTSC 2019 (x64) - DVD (English) from the MSDN downloads page, the file's name is en_windows_10_enterprise_ltsc_2019_x64_dvd_be3c8ffb.iso and the SHA1 hash of the file is D5B2F95E3DD658517FE7C14DF4F36DE633CA4845 I would like to request for someone to verify whether this is a legit copy of the file. I have a feeling that the man might have sent me a wrong file. This file is supposed to be from MSDN and activated with the MSDN key.

:)

 

Verifying integrity of Windows 10 ISO

I have just downloaded the Windows 10 ISO using the Microsoft Media Creation Tool but, before burning it to a DVD, how do I verify its integrity and ensure that none of the files are corrupted? Is there a way?

 

Problem with Lenovo integrated camera

Hi,

Thank you for posting on Microsoft Community. I understand the inconvenience you are facing. I will certainly help you with this. This issue may arise due to driver corruption issue. Kindly follow the below given steps to
troubleshoot the issue:

Method 1:

I suggest you to run the Hardware and Devices

• Select Troubleshooting.
• Select View all on the top left corner.
• Click on Hardware and Devices.

Method 2:

You may also update the Camera driver from Device Manager manually and check if this helps.

• Press (Windows key + X) and click on “Device Manager”.
• Expand “Other devices”.

• Right click on the “Integrated webcam” drivers and select “Update Driver Software”. Once this is done, restart the computer and check if the issue persists.

Method 3:

If issue persist, I suggest you to try installing it in compatibility mode. Compatibility mode runs the program using settings from a previous version of Windows. Follow these steps to install the drivers in compatibility mode and check if that helps.

• Download the Integrated webcam drivers from the manufacturer’s website.

• Right-click on the driver setup file and click on ‘Properties’.
• Click on the ‘Compatibility’ tab and check the box
  ‘Run this program in compatibility mode for’ and select Windows 8/8.1 operating system from the drop down menu and proceed with the installation. Once this is done, restart the computer and check if the issue persists.

Hope this information is helpful. Do reply if you need further assistance, we will be happy to help you.

Thank you.

 

UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files  


I have mentioned this before. The initially downloaded .cab files are only compressed XML files. These XML-files contain the list of required files for each package, including the SHA1 hash. What UUP does is it decompress the .cab and read the file lists. Then it verifies that the local files exists that are in the list and does integrity check for the found local files using the SHA1 value defined.

After all .cab/XML files has been processed, UUP has a list of files it can copy from local HDD to the SoftwareDistribution folder. While it copies the files it automagically also verifies the integrity of that file it has written to new location. Once all files are copied UUP starts to process the second list which is the download list (the missing or updated files) and downloads all new files and while writing to disk also verifies the SHA1 integrity.

Finally UUP prepares Windows for updating/upgrading and sets a schedule to reboot computer and changes the boot option so that the second preparation phase start during shutdown/reboot. Once this is done the computer reboots and the upgrade process runs exactly as it would when upgrading using the setup media.

For me going from finding 15031 in a VM with 15025, 2GB ram and 2 CPU cores, took about 45 minutes to find the update, download it, verify it, install it, and get back to the updated desktop. All using UUP. I was monitoring each step, processes running, HDD usage, network usage, everything, and what I mentioned above is what I found out.

It may not be 100% exact information, but I am sure it's pretty darn close to the truth. :-D


EDIT: The above mentioned ActionList.xml contain the names of the actual packages to be downloaded. The files being downloaded based on this list are the XML/CAB files that contains the detailed list of each and every file required for that particular package. With all the XML/CAB lists put together, we have about 50-60k files that are needed for a full Windows installation.
