Windows 7: 0xc00000e9 error after Windows 7 update

0xc00000e9 error after Windows 7 update

Using the Windows 7 automatic update manager, I installed several system updates including SP1. This is on a month-old, perfecly running Lenova laptop with Windows 7 64 bit Pro.

The updates seemed to install without a hitch. On the reboot, windows configured itself and booted normally. Nothing worked. Clicking icons for Word or Powepoint did nothing. Firefox opened but immediately hung up. I was able to shut the machine down, but the reboot hung up on the opening windows logo. I launched windows repair but it stopped after experiencing "an unexpected I/O error. 0xc00000e9." Safe mode also hung up. At the moment my new laptop that was purring along before this is now an attractive doorstop.

this may be the last straw on the way to linux.

Unplug any USB devices, such as external hard drive, printer, Ipod, etc ... then shut down. Start computer and see if you get the error.

Windows 10 Pro x64

According to the standard Win32 error codes, that error is:
# for hex 0xc00000e9 / decimal -1073741591 :
  STATUS_UNEXPECTED_IO_ERROR                                    ntstatus.h
# If an I/O error is returned which is not defined in the
# standard FsRtl filter, it is converted to the following
# error which is guaranteed to be in the filter.
# In this case information is lost, however, the filter
# correctly handles the exception.
# 1 matches found for "c00000e9"
At the current moment, I'd use a restore point to go back to the point before the updates were installed. After that, I'd suggest as a precaution that you make sure all of my drivers and BIOS were at their latest supported versions for Windows 7. Next, due to the specific error code you see, you must make absolutely certain that any 3rd party antivirus, system security, or firewall software was updated to the latest supported version for Windows 7. After that, I'd recommend attempting to install the updates again, and only after the aforementioned was completed.
