Windows 10 Manual Update permits you to manually update your Windows 10 machine by searching for and displaying updates so you can choose.
Having the ability to choose what update and when you get it is perfect for those users that prefer to allow others to be beta testers. This control allows you to let some time pass before committing to installing a buggy update. Windows 10 Manual Update solves this by searching for all applicable Windows 10 updates and listing them from a simple split-pane UI. Each found update has a checkbox, so you select the one you want. Additionally, in the bottom pane, there is a description of the target update.
Before running Windows 10 Manual Update, you will need to turn off automatic updates installation. You can do it via Group Policy Object Editor MMC snap-in or via importing registry files into Windows Registry. If you choose the registry method, make sure to back up the registry.
To do it via MMC:
Press Win+R. Type mmc.exe. Hit Enter.
Navigate menu File -> Add/Remove Snap-in. Select Group Policy Object Editor, click Add to add it to the list on the right. Click Finish, then OK.
On the left navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update. Select that folder.
In the list, select Configure Automatic Updates policy and set it to Disabled. This setting will disable automatic updates check and installation, but if you navigate to Updates in Windows Settings, you'll implicitly launch automatic updates check and installation.
Change other options in MMC, if you know what you're doing.
