Microsoft released an out of the band security update for Windows 10 systems earlier this week. The patch brings critical security fixes including the infamous SMBv3 protocol bug for the OS.
As a quick reminder, the Windows maker inadvertently revealed the bug with the release of this month’s Patch Tuesday Updates. Later on, the company also released an advisory that suggested users some workarounds to deal with the SMB 3 protocol bug.
Now Microsoft has gradually started rolling out the patch to all PCs running Windows 10 v1903 or 1909 this week. Microsoft says that the update is available for download via WSUS, Windows Update, or the Windows Update Catalog. However, it seems like the update brings a new series of problems for your machines.
People are complaining about the fact that Microsoft has released this emergency update without testing. According to the various reports on Microsoft forum and Reddit, people are currently dealing with the following issues:
Windows 10 KB4551762 Brings More Bugs Than Fixes
High CPU Usage Bug
In a forum report, people confirmed that the latest update may reduce your system’s performance and cause high CPU usage issue. A frustrated user explained:
“After installing the March 12, 2020—KB4551762 you might encounter high CPU Usage with process VMMEM if you have Hyper-V Services enabled, an Easy fix is to go to Apps & Setting and uninstall reboot then reinstall the features this will flush the store cache procedure for rapid execution of app launch / service launch.”
Automatic Installation Issues
A Redditor who installed the patch noticed that the system reboots randomly without any prior notice. Notably, PC completely ignores active hours while rebooting multiple times.
Moreover, another report suggests that when the update downloaded on the system, it asked the OP to either “Restart now” or “wait until my active hours” to complete the installation process.
However, it is worth noting that the message itself appeared during active hours. So, the systems should already have restarted, but it didn’t.
Error Code 0x80071160
Windows 10 cumulative updates have always been affected by the installation issues. Unfortunately, those who are trying to install KB4551762 reported [1, 2, 3, 4] that they are experiencing a similar problem. Someone wrote on Microsoft Answers forum:
“These issues began yesterday 3/13/20. The update, “2020-03 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4551762)” has failed every time I try to install it with the error code, “0x80071160″. When this issue began my disk drive also went up to 100% with little change. I restarted my pc multiple times but both issues persisted. Could anyone help me, please?”
If you have encountered any of these issues on your machine, don’t forget to remove the patch and use the automatic repair option to fix them. But if your computer remains buggy and slow, you still have the option to do a clean installation of Windows 10.
