For most people, Windows 10’s latest update simply won’t be an issue.....However, a number of users running Windows 10 KB4551762 found that their PCs appears to have slowed down and some have also noticed an abnormal hike in CPU/disk usage.
This is exactly what happened to me this morning...Microsoft.......????????? what are your tech's doing
It is easier to uninstall Windows 10 updates if they are causing problems for you. To uninstall the patch, head to Settings > Update & Security > Update history. In the updates history page, click on Uninstall updates option, which should open Control Panel where you have to select the update and click on uninstall button.
