A.How do I keep my PC up to date?

The best way to keep your PC current is to turn on automatic updates. With automatic updates, you don’t have to search for updates online or possibly miss critical fixes or device drivers for your Windows PC. Windows Update automatically installs important updates as they become available.
If your PC is connected to a network where updates are managed by Group Policy, you might be unable to change settings related to Windows Update. For more info, contact your organization’s support person.
If you’re using Windows 10 Pro or Windows 10 Enterprise, you can choose to temporarily pause updates from being downloaded and installed. This option isn’t available in other versions of Windows 10, including Windows 10 Home:

1. Select the Start  button, then select Settings  > Update & security  > Windows Update . Under Update settings, select Advanced options.
2. Turn on Pause updates. Note that, after a certain amount of time or after canceling a pause, you'll need to install the latest updates before you can pause updates again.

B.How do I manually check for and install updates?

To manually check for updates in Windows 10:
Select the Start  button, then select Settings  > Update & security  > Windows Update . If you want to check for updates manually, select Check for updates.
 

C.How do I see installed updates on my PC?

An update history is available so you can see which updates were installed, and when. You can also use this list to remove specific updates, although we don't recommend this unless it's necessary.
To see update history in Windows 10:
Select the Start  button, then select Settings  > Update & security  > Windows Update  > Advanced options > View your update history.
For more info about what’s included in updates for Windows 10, see Windows update history(https://support.microsoft.com/en-us/help/4099479)

D.How do I remove an installed update?

We don’t recommend that you remove any installed updates. However, if you must remove an update, you can do so from the update history.
 
To remove an update in Windows 10:
Select the Start  button, then select  Settings  > Update & security  > Windows Update  > Advanced options > View your update history > Uninstall updates.
Select the update you want to remove, then select Uninstall.

E.What can i do if I’m having problems installing updates?

• Make sure that your PC is connected to the Internet. Some updates can’t be installed if you’re using a metered Internet connection.
• If you’re connected the Internet and updates aren’t installed automatically, wait a few minutes and then try to install the updates manually.
• Use the Windows Update Troubleshooter to try to fix the problem.
