Frequently Asked Questions

Why won’t my PC finish installing updates?

If you are having trouble completing software updates, it could be because your computer isn’t connected properly to the Internet. This includes wireless networks, mobile broadband connections, and dial-up modems. You’ll want to make sure that you’ve got a good connection to the network, whether wired or wireless. If you don’t, you might be missing out on important updates.

The next thing to check is how much free hard disk space you have left. Updates take up quite a lot of room, especially when downloading large files like security patches. So, make sure that you have enough space to install the update without running out of disk space.

Finally, try restarting your computer or booting into safe mode. When you do, you’ll bypass some of Windows’ normal startup processes and start with just what’s necessary to run the operating system. You won’t see anything else, including programs and personal data, so you won’t miss out on anything important. Once you’re done, exit safe mode to return to regular operation.
