KB4535996 Major fixes and changes
It’s a huge but non-security update. Its emphasis is on delivering different fixes for the users.
You can skip it if you want because it will be offered as a part of the mandatory Microsoft Patch Tuesday release of next month. But the bugfixes mentioned on the KB4535996 support page are interesting enough that I would definitely recommend installing this update.
Although there are a lot of fixes mentioned on the support page, I will only list down the major ones here:
- Microsoft introduced modern standby mode support in Windows 10. The modern standby mode provides a smartphone-like always-connected experience on a Windows 10 laptop. Some users were complaining that it was causing their laptops to overheat when on standby. This update introduces a new version of modern standby for Windows 10 and will improve laptop battery performance.
- Fixing keyboard layout changes after restart
- Fixing printing bugs and issue which prevents apps from printing to some network printers.
- Fixed an issue in Microsoft browsers that might cause the browsers to bypass proxy servers. The browsers may include Internet Explorer, Microsoft Edge, and Microsoft Edge Chromium.
- Fixed a Group Policy issue that caused the policy “Allow uninstallation of language features when a language is uninstalled” from taking effect.
- Fixed a Windows Search box issue that prevented it from “rendering fully in the space allotted for it2. And also fixed an issue with Windows search that prevented from showing results.
- Fixed an issue with Network Profile Service which forced the system to stop responding.
- Fixed an issue with Local Security Authority Subsystem Service to stop working and trigger a system restart automatically.
- Fixed a log corruption issue when a storage volume is full.
- Fixed a Remote Desktop session disconnect issue.
- Fixed a certification issue that caused Internet Explorer mode on Microsoft Edge to fail.
I have been going through Microsoft and Reddit forums and have seen some complaints about issues after installing the KB4535996 update. Some are unable to install the update while getting 0x800f0922 and 0x80070003 error messages. For some users, the update freezes while installing and some users are also seeing BSODs when they restart the computer after installing this update.
I installed it on my computers and laptops but didn’t encounter any error. The installation went smoothly and completed successfully. I can say that only a very small percentage of users will have problems with this update. If you are one of them, you should uninstall the update.
