Windows 10: Failed to read Delta Log

I have been trying to figure this out for some hours now but have found no resolution. I had a black screen on my laptop when I opened it, as I normally dont turn it off, and I was tryign to turn it on but nothing would work so I held the power button to turn it off and then turned it back on.

Delta size too big when creating patches

I'm using WiX to create installers and patches for an application. We previously used a bdiff-based method to create patches, and are able to get comparable results in
WiX which uses Delta patching (specifically mspatchc.dll) (https://msdn.microsoft.com/en-us/library/bb417345.aspx)

However one particular file has deltas much larger than expected - from an original 100MB file, bdiff will create a
15KB patch, while Delta returns an 18MB patch.

I've raised the issue on the WiX-users mailing list, and feedback from there suggests that the issue might be in Delta itself. Is there anything I can try to reduce the patch size myself, or is this something that needs fixing?

 

Error Log Reading

Hi ankurshaswat.

Sorry I can't tell from logs but all data appears to be very old. Like September. Here is a list of quick fixes that can help from an MS article.

Quick fixes The following steps can resolve many Windows upgrade problems.

• Remove nonessential external hardware, such as docks and USB devices.
• Check all hard drives for errors and attempt repairs. To automatically repair hard drives, open an elevated command prompt, switch to the drive you wish to repair, and type the following command. You will be required to reboot the computer if the hard drive being repaired is also the system drive.
  • chkdsk /F
• Attempt to restore and repair system files by typing the following commands at an elevated command prompt. It may take several minutes for the command operations to be completed. For more information, see Repair a Windows Image.
  • DISM.exe /Online /Cleanup-image /Restorehealth
  • sfc /scannow
• Update Windows so that all available recommended updates are installed, and ensure the computer is rebooted if this is necessary to complete installation of an update.
• Uninstall non-Microsoft antivirus software.
  • Use Windows Defender for protection during the upgrade.
  • Verify compatibility information and re-install antivirus applications after the upgrade.
• Uninstall all nonessential software.
• Update firmware and drivers.
• Ensure that "Download and install updates (recommended)" is accepted at the start of the upgrade process.
• Verify at least 16 GB of free space is available to upgrade a 32-bit OS, or 20 GB for a 64-bit OS.

Once you done all of the above could I suggest you follow this tutorial to install the upgrade. While non destructive I would recommend backing up all data off device.
