Windows 11 common problems — and the fixes

Microsoft has finally started the gradual rollout of Windows 11, the most significant refresh in more than a decade. In this new version, you will find many significant changes and features, including a fresh new interface with rounded corners and transparent elements. There's a new Start menu and Taskbar that now are front and center. Action Center has been replaced for two new experiences known as Notification Center and Quick Settings. You will find a new version of Settings, and there are several new features, such as Widgets, Chat from Microsoft Teams, Snap layouts and Snap groups, Auto HDR and DirectStorage for a better experience, and much more.

Although the company has finalized the development earlier to spend more time tweaking and fixing bugs and other problems before the official release date, the new version includes many code changes that could mean many unknown issues, compatibility problems with hardware and drivers, and more.

Since Windows 11 requires complete reinstallation, computers may also experience other problems that are not caused by the new version. Instead, the upgrade process may get stuck or fail because of driver issues, incompatible applications, device drivers, custom configurations, or problems with some pieces of hardware.

In this Windows 11 guide, we will share some of the problems you may encounter during and after the installation and their possible solutions.

Windows 11 fixes to common problems

On Windows 11, you may come across two types of problems. You can stumble upon commonly known issues during and after the upgrade, such as problems with storage, features, activation, and updates that are not problems directly tied to the new OS.

Also, there are those problems that are direct results of bugs with the new version. For instance, the installation may fail because of a compatibility issue with an app or hardware, or these problems could be related to drivers and security software like antivirus.

Since Windows 11 is based on Windows 10, the same installation problems you may see on Windows 10 are likely to appear on Windows 11.

This guide focuses on helping you get around common upgrade problems and steps to mitigate specific known issues (if available) during and after the installation.

How to printer setup problem on Windows 11

If your Windows 11 computer connects to a network printer, during the initial setup, the system may fail to download and install the device drivers because of a compatibility issue between the printer server using an HTTP connection with the new version of Windows 11.

If you encounter this issue, it's recommended to download and install the printer driver manually from the manufacturer's support website.

The manufacturer will have specific instructions to install the driver and connect the computer to the network printer. Typically, you only need to launch the setup wizard and continue with on-screen directions.

In addition, Microsoft has also acknowledged two other networking printer issues, but these scenarios are not commonly seen in home computers. Instead, these printing issues could affect printing solutions in organizations.

The first one includes a problem with the printer server where the client may not receive the custom configuration. This won't affect the printing experience, but custom settings may not apply to the client. Then the second one is an issue that may prevent the computer from installing the printer successfully using Internet Printing Protocol (IPP).

Microsoft has acknowledged these problems, and it's working on the fixes that it plans to release in future updates.

Windows 11 tips to minimize installation problems

Although the upgrade process to Windows 11 should go smoothly since the company will try to offer the new version only to those devices known to have a good upgrade experience, you may still come across a problem during and after the installation. However, if you plan ahead, you will minimize the chances of problems. And if you do come across problems, you will be able to recover quickly without losing your files.

Create temporary backup

A full backup is perhaps the best recovery strategy if something goes wrong with the installation and you need to roll back. It's also an excellent way to protect your files.

If you use specific backup software, use it to create a security copy before the upgrade. If you don't, you can always make a temporary backup using the imaging tool available on Windows 10. In addition, it is also recommended to create a file backup to an external drive or cloud using OneDrive.

Disable metered connection

A metered connection will prevent Windows Update from downloading the Windows 11 files. If you plan to upgrade through Windows Update, make sure the connection is not configured as metered.

If you have a capped internet connection, connect to another network or disable the metered connection (assuming that you have enough data left) to upgrade to Windows 11.

To disable a metered connection on Windows 10, use these steps:

1. Open Settings.
2. Click on Network & Security.
3. Click on Wi-Fi or Ethernet.
4. Select the active network connection.

5. Under the "Metered connection" section, turn off the Set as metered connection toggle switch.

After you complete the steps, Windows Update should be able to download the Windows 11 files on the computer.

Uninstall non-essential apps

Applications that were not designed for Windows 10 or Windows 11 can cause compatibility problems. You can always avoid these issues by removing those apps that may cause problems before the installation. These apps usually are old programs and third-party security solutions.

To uninstall apps on Windows 10, use these steps:

1. Open Settings.
2. Click on Apps.
3. Click on Apps & features.
4. Select the app you want to remove, and click the Uninstall button.

5. Click the Uninstall button again.
6. Continue with the on-screen direction (if applicable).

After you complete the steps, repeat the instructions to uninstall the remaining apps as necessary.

Also, if you use a third-party antivirus or firewall, check the software support website for specific details on how to disable or uninstall the application. After the installation, you can reinstall the apps again.

Disconnect non-essential peripherals

Non-essential peripherals (USB flash drives, SD cards, external hard drives, printers, scanners, dongles, and Bluetooth devices) can cause the installation to fail. If you have any peripherals connected to the computer, disconnect them. You only need a monitor, keyboard, mouse, and internet connection.

After the installation, you can reconnect the peripherals to the computer.

Start fresh with a clean installation

If you have tried many troubleshooting steps, you should stay on Windows 10 and wait a little longer. If you cannot wait, consider doing a clean installation of Windows 11.

The reason is that the laptop or desktop computer will start with a fresh copy of Windows 11, which can also help resolve other problems with the previous installation. On the other hand, an upgrade modifies the previous setup, which can cause problems.

A clean installation is almost a straightforward process. It only takes more time since you need to create a USB flash drive and reconfigure the system after the installation. You can use this guide with all the steps to perform a fresh install of Windows 11.
