KB4025342 causing extremely long boot time


Installed update KB4025342 automatically through Windows Update on July 12. Noticed extremely long boot up times of the order of 10 mins for a laptop that normally gets to desktop in under 1 min. Repeatedly happened over several shut downs and boot ups.

So I uninstalled the update and PC is back to normal. Again, have done several shut downs and boot ups.

Seems like this KB4025342 is the culprit. Wonder if anyone knows how to report this and what I should do now? Wait for different cumulative update or try installing again?

1. When (approx. date) did you purchase the computer?

2. Did the computer come with Win10 preinstalled, did you do a clean install of Win10, or did you upgrade a Win7 computer or a Win8.1 computer [<=PICK ONE!] to Win10?

3. Who manufactured the computer (e.g., Dell; HP; Acer; Lenovo; ASUS)?

4. Has a Norton application or a McAfee application EVER been installed on the computer since you bought it?

5. Have you ever run the Norton Removal Tool and/or the McAfee Consumer Products Removal Tool?

6. What Version & OS Build of Windows 10 is currently installed?

  • Press & hold the Windows Key and press the R key. In the RUN dialog, type WINVER and press the Enter key.

7. Was Creators Update offered and installed via Windows Update or did you choose to install it manually?
