You probably haven’t heard of Sign Tool, but it’s an important program for admins who verify and sign files. When the failed KB4535996 update installs, users are getting hit with an error message, and are forced to uninstall the update (which is probably for the best, anyway). As I mentioned, some users are unable to boot up their systems altogether. Now, those that can are complaining that the booting process is taking longer than normal. The worst-case scenario is if your system boot loops, or gets stuck in an endless cycle of restarting. If that happens to you, then boot your system in Safe Mode, go to Settings and uninstall the Windows 10 KB4535996 update. Even gaming PCs are suffering from the update, with some users reporting significant frame-rate drops. This suggests the update is straining the components inside these systems.
Microsoft says everything is OK
Microsoft has yet to acknowledge any of the complaints being made across various forums and social media platforms. The official update page (opens in new tab) even says “Microsoft is not currently aware of any issues with this update.” I reached out to Microsoft to ensure they were aware of these reports, and will update this article if I get a response. In the meantime, your best bet is to uninstall the KB4535996 update and wait for a fix to the “fix.” Below are simple steps on how to uninstall a Windows 10 update and revert to a more stable state. Oh, and you should probably save these instructions for the next inevitable Windows 10 update fail.
Go to the Window Start Menu and click the Settings gear. Choose Update & security.Press the Windows Update tab on the left sideClick the View update history option.Click the Uninstall updates link at the top of the page.Choose the KB4535996 update to uninstall it.
