15 Common Windows 11 Problems and How to Fix Them

Rebooting, installing updates, updating or rolling back the required driver, and running sfc /scannow to fix system files are the same ways to solve most of the Windows 11 issues, from a slow computer to a Start menu that won’t open. In this guide, we list the 15 most common issues we see, the quickest fix for each, and a link to a full guide where there is one.

What Should I Do First for Every Windows 11 update?

Do a full restart, then go to Settings > Windows Update and install all updates, including optional driver updates. If the “windows 11 update issues”persists, repair the system files by opening Terminal (Admin) and running DISM /Online /Cleanup-Image /RestoreHealth and then sfc /scannow. These three things can fix a very large percentage of normal mistakes.

Use Restart instead of Shut Down. With Fast Startup enabled, Windows does not reload the whole system when it is restarted. Instead, it shuts down by saving a part of the system’s state and restoring it the next time. You can only do a full reload of Windows by restarting it.

Knowing your precise version is also helpful. How to check your Windows 11 version and update to windows 11 26h2 release date is explained in our guide, along with the importance of sticking with a supported version.

What we often see: a problem that “just started happening” actually started on the day a driver or application was installed. Problem 15 discusses Reliability Monitor and makes the link clear.

Why Does Windows 11 Operate So Slowly?

The most common causes of a slow Windows 11 computer include an almost full system drive, too many apps opening at startup, background programs eating memory, or a computer that hasn’t been restarted in days. Use Ctrl + Shift + Esc to launch Task Manager, examine startup programs, and turn off anything you don’t require when logging in.

• Choose Startup programs in Task Manager, then right-click any unnecessary items and choose Disable.
• To automatically delete temporary files, verify the available space in Settings > System > Storage and enable Storage Sense.
• From Settings > Apps > Installed apps, remove any programs you are no longer using.
• Use Windows Security > Virus & Threat Protection > Scan options to perform a full scan.

Cause and effect: Windows has less space for its page files and update files when the system drive is extremely full. This results in overall slowness and, as a consequence, unsuccessful updates.

Why Does Windows 11 Use So Much CPU Power?

One process, such as Windows Update, antivirus scanning, search indexing, or a misbehaving app, is typically responsible for high CPU consumption. To locate it, open Task Manager, choose Processes, then sort by the CPU column. Consistently high CPU utilization from a single app is abnormal; however, brief spikes during startup or updates are considered normal.

Update or reinstall the offending app. Allow a system process, such as the Windows Modules Installer Worker or Antimalware Service Executable, to complete its scan or update before passing judgment.

System interrupts or persistently high system use frequently indicates a driver. Updating or rolling back the offending driver is covered in our guide on locating and updating Windows 11 drivers.

What Causes Windows 11 Upgrades to Consistently Fail?

The most frequent reasons why a Windows 11 update fails are low disk space, a corrupted update cache, corrupted system files, or an interrupted download. Ensure you’ve cleared up a few megabytes of space at least, then run the Windows Update troubleshooter from Settings > System > Troubleshoot > Other troubleshooters. After restarting, select Check for updates again.

Use the DISM and SFC repair procedures mentioned above if an update still doesn’t work, then try again. Take note of the error code that indicates the precise problem on the Windows Update page.

Go to Settings > System > Recovery and choose Reinstall now under Fix problems using Windows Update as a last resort before restarting. This preserves your apps, data, and preferences, according to Microsoft’s instructions for reinstalling the most recent windows 11 update issues.

What Could Be the Reason for Windows 11 Indicating That It Isn’t Activated?

The “Activate Windows” watermark indicates that Windows is unable to verify that your edition license is valid. A new motherboard, a key for a different version, a reinstall without the original key, or an invalid key are common causes. Windows displays the problem and provides the Troubleshoot option when you check the status in Settings > System > Activation.

What to do next is indicated by the error code. The two most frequent ones are described in our guides: error 0x803FA067 following a hardware change and error 0xC004F050, the invalid product key issue.

PCs that are not activated will continue to work but will show a watermark and cannot be customized. If you need a new license, a valid Windows 11 Pro or Windows 11 Home key activates from the same activation page. Do not use programs called “activators” or KMS scripts, as these are not properly licensed and may contain malware.

Why Does Windows 11 Keep Disconnecting My Wi-Fi?

In Windows 11, Wi-Fi disconnects are most often due to a router issue, an outdated network adapter driver, or the adapter’s power-saving settings. First, update the Wi-Fi driver using optional updates from Windows Update or your PC manufacturer. If that doesn’t work, go to Settings > Network & internet > Advanced network settings > Network reset.

To rule out a transient issue, restart both the PC and the router.

Please verify if other devices are experiencing connectivity issues as well. If they do, the router or broadband connection is the issue.

Run the Network and Internet troubleshooter under other troubleshooters after updating the Wi-Fi driver.

Choose Reset now after using Network Reset. You will need to reconnect to Wi-Fi and reinstall any VPN software after removing and reinstalling network devices and resetting their settings.

Advanced nuance: If the Wi-Fi only fails when the computer wakes up from sleep, open the adapter in Device Manager and check the Power Management tab. Uncheck the box that allows the computer to turn off this device to save power. This often stops the problem.

Why Does Windows 11 Not Support Bluetooth?

The most common reasons why Bluetooth fails are that it is turned off, the device is paired incorrectly, or the Bluetooth driver needs to be updated. Navigate to Settings > Bluetooth & devices, switch Bluetooth on and off, then remove the troublesome item and re-pair it. The adapter driver is either disabled or missing if the Bluetooth toggle is completely absent.

Look for a Bluetooth category in Device Manager. Update or reinstall the driver from the support page of your PC manufacturer if it is missing or displays a warning triangle.

The hands-free profile may be used by Bluetooth headphones that connect but produce subpar sound. In the sound settings, choose the stereo output rather than the hands-free one.

Why Is Windows 11 Not Allowing My Printer to Function?

The most common causes of printer issues are an out-of-date printer driver, a stopped Print Spooler service, or a stalled print queue. Restart the Print Spooler service after cancelling every job in the queue. If it doesn’t work, take the printer out of Settings > Bluetooth & devices > Printers & scanners and put it back in.

• Press Windows key + R, type services.msc, and hit Enter.
• Locate Print Spooler, then choose Restart with a right-click.
• Choose Remove, then Add device after selecting the printer under Printers & Scanners.

If Windows’ built-in driver is inadequate, install the most recent driver or software from the printer manufacturer’s website.

For network printers, make sure the printer’s IP address hasn’t changed and that the printer and PC are connected to the same network.

Why Are the Taskbar, Search, and Start Menu Not Functioning?

Restarting Windows Explorer frequently resolves issues with the Start menu, search box, or taskbar. Hit Ctrl + Shift + Esc, locate Windows Explorer in Processes, then right-click on it and choose Restart. The desktop and taskbar vanish for a moment before reloading. Use DISM and SFC to repair system files if the issue reappears.

Check Settings > Personalisation > Taskbar > Taskbar behaviours and make sure Automatically hide the taskbar is disabled if the taskbar keeps disappearing. The same section determines which screens display it in multi-monitor setups.

Check which locations are indexed by opening Settings > Privacy &security > Searching Windows if search yields no results for files, you know exist. Although it takes some time, rebuilding the index under Advanced indexing options corrects outdated results.

We frequently personalize our settings and look for issues. Behaviors that occur immediately after a feature hides in the taskbar will resolve themselves following the next cumulative update. Before doing more extensive fixes, it is recommended to install all pending updates.

Why Is My Windows 11 Computer Not Producing Any Sound?

The most common reason for no sound is choosing the incorrect output device, particularly after putting in a dock, monitor, or headphones. Navigate to Settings > System > Sound, choose the appropriate device under Output, and then adjust the volume. Update or reinstall the audio driver if the correct device is missing.

Examine the obvious items as well, such as muted speakers, a detached security device, or a monitor with no sound input set for output. These are automatically checked by the audio troubleshooter under Other advanced tools.

Open Device Manager, expand Sound, video, and game controllers, and use Roll Back Driver on the audio device if sound has stopped following an upgrade.

Why Is My Windows 11 Screen Black?

A black screen can mean Windows Explorer crashed; the computer is sending video to the wrong monitor, or a graphics driver has failed. Reset the Graphics Driver by pressing Windows key + Ctrl + Shift + B. Press Windows key + P to check the projection mode. If a cursor appears, restart Windows Explorer from the Task Manager.

Safe Mode and driver rollback are covered in our comprehensive guide to Windows 11 black screen scenarios, both with and without a cursor.

Why Is the Battery on My Windows 11 Laptop Going So Quickly?

High screen brightness, background programs, or a process that prevents the laptop from sleeping are typically the causes of rapid battery loss. To find out which apps consume the most power, navigate to Settings > System > Power & battery and select Battery usage. Using Quick Settings to activate Energy Saver is also beneficial.

Introduced in Windows 11 24H2 to replace Battery Saver, Energy Saver reduces screen brightness, disables transparency effects, and restricts background activity. The specific adjustments are listed in Microsoft’s Energy Saver documentation.

Check battery utilization for apps that were running during the night if the battery declines while the lid is closed. Sleep behavior is frequently improved by updating the BIOS and chipset driver of the Windows laptop manufacturer.

Why Does File Explorer Freeze or Run Slowly?

A disconnected network drive, a big media folder being scanned for thumbnails, or a cluttered Quick Access history are frequently the causes of a slow File Explorer. Restart Windows Explorer from Task Manager, disconnect any network drives you no longer use, and clear the history from Folder Options. Numerous Explorer issues are also fixed by updating Windows.

• Choose See more (the three dots) in File Explorer.
• Choose Clear under Privacy in the General tab.
• On This PC, right-click on the network drive that is no longer accessible, then choose Disconnect.

Cause and effect: When File Explorer opens, it attempts to access all mapped drives and recent locations. The window may take a long time to respond if there is one unavailable network share.

Why Does Windows 11 Frequently Crash and Restart?

To view a timeline of crashes along with recent installs and upgrades, use Reliability Monitor by typing perfmon /rel. For further information, see the Application Log for Event ID 1000 (app crash) and Event Viewer > Windows Logs > System for Event ID 41 (unexpected restart) and BugCheck events. Usually, the cause is shown by the time.

Filtering the logs and reading these events is explained in our tutorial on utilizing Event Viewer to detect faults and failures.

If the solutions in this tutorial don’t work, go to Settings > System > Recovery. You can choose to keep your personal files and reinstall Windows by resetting this computer. Before you begin, make sure you know how to activate your copy of Windows and make a backup.

Common Questions (FAQs)

Is Windows 11 26H2 More Reliable Than Previous Iterations?

Every new version gets security updates for a longer period of time, and fixes issues found in previous versions. The support period for “microsoft windows 11 26h2 release”Home and Pro is October 10, 2028. Updates with new features may have their own early issues, which are often resolved in subsequent monthly cumulative updates.

Will Most Issues Be Resolved by Rebooting Windows 11?

Because a reset reinstalls Windows from scratch, it resolves the majority of software issues. It eliminates installed software even if you save your files, and it won’t repair malfunctioning hardware. Prior to selecting a complete reset, try updates, driver patches, DISM and SFC, and the Reinstall Now repair option.

Can Performance Issues Arise from an Inactive Version of Windows 11?

No, not directly. Non-activated Windows 11 runs just as fast, but personalization options are locked, and a watermark appears. The problem with unofficial apps and modified ISOs is that they can introduce malware that can compromise the security of the computer and also slow it down.

How Can I Determine Whether a Problem Is Software- or Hardware-Related?

If the problem also appears in Safe Mode, after Recovery, or before Windows begins, hardware is more likely. Problems after an update, driver change, or a new application are usually caused by software. Reliability Monitor and Event Viewer help show what changes happened first.

Should I Use an App for PC Optimization or Cleaning?

Many cleaning programs are already integrated into Windows 11, such as Storage Sense, Windows Security, and startup app control in Task Manager. Registry cleaners and third-party optimizers tend to remove settings that Windows needs and promote paid upgrades. Use the built-in tools that are discussed in this guide.
