Users have reported that the February update for Windows 10 triggers BSOD errors, blue and black screens before login, performance drops, FPS reduction, audio glitches, and system hiccups. In some configurations, KB4535996 also disrupts power management settings, rendering users unable to put their PCs to sleep.
Windows 10 Sleep Bug in KB4535996 Version
Putting your PC to sleep is an excellent way to save energy, but some users are complaining about Windows 10 waking up automatically after applying an optional update.
One user expressed, 'I can't put my Surface Laptop 2 to sleep. It wakes up automatically after a few minutes, even when the laptop is closed. It seems the update has disrupted the power management system.'
Another user documented an error in a Microsoft forum response, stating, 'This needs to be addressed. We should be able to stop an optional update if it causes issues. I had to pause updates for 7 days and then uninstall KB4535996 again. This update rendered both my PC and laptop unable to sleep.'
Other users have also confirmed this issue: 'This update rendered both of my computers unable to enter sleep mode. Both are running Win 10 Home v. 1909 and functioned normally after I uninstalled the update.'
Another user posted on Twitter: 'Ever since updating to the latest Windows 10 versions, KB4537572 and KB4535996, my computer wakes up on its own every few hours. This didn't happen with previous updates.'
Windows update can also increase boot times or cause startup errors on certain systems. It also interferes with Sign Tool, a command-line utility developers use for Windows applications. However, these issues don't affect all users.
Microsoft has yet to acknowledge sleep mode issues or what might be causing them. The support article still claims the company is not aware of any issues. In the meantime, if you encounter problems, try the Fixes for Windows 10 Sleep Issues here to see if they resolve the issue.
The inconveniences caused by the latest Windows 10 update may be annoying, but they are not overly severe. However, for mobile operating system security issues, millions of Android KitKat-powered tablets are at risk of being hacked, posing a headache for Google, the platform's developer.
