AI Agents for Business Operations in 2026 Examples, Platforms, Risks and How to Start

Image
Product visuals: Microsoft, Zapier, Google Cloud and Salesforce official pages I have worked in IT for about twenty years, and the first thing I tell anyone who asks about AI agents is to separate the word from the product. Vendors now call almost everything an agent, from a chat window that answers questions to a system that updates records on its own. This guide follows the searches people run next on Google (definition, examples, companies, ChatGPT, agentic vs generative AI, McKinsey, how to build) and shows what each one means for running a business. Quick answer An AI agent is software that pursues a goal by planning steps and using tools, not just answering a prompt. Google, Salesforce and Anthropic all describe it this way (sources read October 25, 2026). For Microsoft shops, Microsoft Copilot Studio is a low-code way to build agents and workflows with human review steps. For CRM and service work, Salesforce Agentforce lists a free Salesforce Foundations start and $2 per conve...

Windows 11 Audio Output Not Switching? How to Fix Sound Device and AudioSwitcher Problems (2026)

Quick answer
  • Start with the built-in switch: Settings, System, Sound, or the sound icon in Quick Settings. If it works there, the problem is the third-party tool, not Windows.
  • If Windows itself cannot switch devices, restart the Windows Audio services, run the Audio troubleshooter, and update or reinstall the audio driver.
  • If a third-party switcher such as AudioSwitcher will not open or respond, close it in Task Manager, run it as administrator, and reinstall the latest version as a last step.

You press your audio shortcut and nothing happens, the speaker list is empty, or the switcher app will not open. In Windows 11 the cause is usually a stopped audio service, a driver problem, or a third-party utility that lost permissions after an update. This guide goes from the quickest checks to the deeper fixes, and it does not ask you to edit the registry.

AudioSwitcher Windows 11 fix

1. Switch Audio Devices the Built-In Way

Three ways to switch the audio output device in Windows 11
  • Click the sound icon at the right of the taskbar and use the arrow next to the volume slider to pick an output device.
  • Or open Settings, System, Sound and choose your device under Output.
  • If the device is missing, scroll to Advanced and open More sound settings, then check that it is enabled in the Playback tab.
A USB headset skips many onboard audio problems because it brings its own sound card.
See USB headsets on Amazon →
My take (20 years in IT): Work from the simple to the deep. Confirm that Windows itself can switch devices before you blame a third-party tool, and change one thing at a time.

2. Run the Audio Troubleshooter

Steps to run the Windows 11 Audio troubleshooter
  • Open Settings, System, Troubleshoot, Other troubleshooters.
  • Select Run next to Audio and follow the prompts.
  • Restart the PC if it applies a fix.

3. Restart the Windows Audio Services

Which Windows audio services to restart
  • Press Windows + R, type services.msc, and press Enter.
  • Find Windows Audio and Windows Audio Endpoint Builder. Right-click each and choose Restart.
  • Set both to Automatic in Properties if they are not.

4. Update or Reinstall the Audio Driver

Steps to update or reinstall an audio driver in Windows 11
  • Open Device Manager and expand Sound, video and game controllers.
  • Right-click your audio device and choose Update driver.
  • If that does not help, choose Uninstall device and restart. Windows reinstalls a driver on boot.
  • For laptops, also check the manufacturer’s support page for a newer audio driver.

5. If a Third-Party Switcher Will Not Open

Fix steps for a third-party audio switcher app that will not open
  • Close the app: right-click the taskbar, open Task Manager, find the app, and choose End task.
  • Start it again with Run as administrator.
  • Check Settings, Apps, Installed apps for the app’s advanced options, and use Repair or Reset if shown.
  • As a last step, uninstall it, restart, and install the newest version from the developer’s own site.

Why Audio Switching Breaks

Windows keeps a list of playback devices and remembers which one is the default. That list can get out of sync when you plug and unplug USB or Bluetooth devices, after a driver update, or after a feature update.

A third-party switcher reads the same list through Windows, so if Windows shows no devices, the switcher will fail too. This is why testing the built-in switch first saves time: it tells you which side has the problem.

Keep It Working

  • Install Windows and driver updates, then restart.
  • Unplug devices you no longer use so the list stays short.
  • Keep a note of the default device you want and set it in Settings, System, Sound after big updates.
  • If you use a switcher app, update it after major Windows updates and allow it to run at startup.

My take (20 years in IT): If you reach the driver step, note what you changed so you can undo it. Avoid registry edits for a problem that a service restart or driver update can fix.

Frequently Asked Questions

Why does Windows 11 not show my headphones?

Check that the device is connected and enabled in More sound settings, restart the Windows Audio services, and update the audio driver.

Is AudioSwitcher part of Windows?

No. Windows has its own switcher in Quick Settings and Settings. AudioSwitcher and similar tools are third-party apps that add shortcuts.

Do I need to edit the registry?

No. These fixes do not require registry changes. Avoid registry edits unless a trusted source tells you exactly what to change, and back up first.

What if Bluetooth audio keeps disconnecting?

Remove and re-pair the device, update the Bluetooth driver, and keep the device close to the PC.

Core Ultra 9 285K vs Core i9-14900K for Gaming in 2026: What the 200S Plus Refresh Changed

Image
Quick answer In 2026 the better Intel buy is usually the Core Ultra 7 270K Plus, not the 285K or the 14900K. Back2Gaming found it essentially matches the 285K in productivity for about $290 less. For pure gaming, AMD’s X3D chips still lead. Back2Gaming reports the Ryzen 7 9800X3D wins by 20 to 50 percent in some titles. At 4K, the graphics card is usually the limit and CPU differences shrink to about 5 to 10 percent . When Intel’s Core Ultra 200S launched in 2024, early tests showed it trailing the Core i9-14900K in many games, and a comparison between them was popular. Two years later the situation has changed. Intel released the Core Ultra 200S Plus refresh in March 2026, the 14900K sits on a dead-end socket, and AMD’s X3D chips set the gaming bar. This guide explains where each chip fits now. 1. What Changed in 2026 Intel unveiled the Core Ultra 200S Plus series on March 11, 2026, led by the Core Ultra 7 270K Plus and Core Ultra 5 250K Plus. Intel says these are its fastest d...

How to Connect Two or More Monitors to an M1 MacBook: DisplayLink Dock Guide (2026)

Image
Quick answer A standard M1 or M2 MacBook (and the MacBook Neo) natively supports only one external monitor. M1 Pro supports two, and M1 Max supports four. To add more screens on a base M1, you need a DisplayLink or InstantView dock plus a free driver. A simple HDMI splitter will not give you separate screens. The trade-offs are a 60Hz refresh cap, a small amount of latency, and no HDCP-protected streaming on those extra screens. You bought an M1 MacBook, plugged in a second monitor, and found that macOS will not let you extend to both. That is not a setting you missed. It is a hardware limit of the base chip. The good news is that a USB graphics dock can work around it. This guide explains which MacBooks have the limit, how the workaround works, which docks Macworld tested, and what you give up. 1. How Many Monitors Your MacBook Supports Macworld explains that Apple’s lower-end MacBooks with a standard M1 or M2 chip cannot natively connect more than one external monitor. The M...

iPhone Battery Percentage Wrong or Jumping? How to Check Battery Health and Fix It (2026)

Image
Quick answer Check Settings, Battery, Battery Health & Charging first. If maximum capacity is low or a service message appears, the battery is aging, not just misreporting. iPhone batteries cannot be calibrated by the user. Restart, update iOS, and give the phone a few normal charge cycles before you assume a fault. If the percentage keeps jumping, drops to 1 percent and recovers, or the phone shuts down, book a battery check with Apple or an Apple Authorized Service Provider. Your iPhone says 40 percent , then 15, then 38. Or it will not stay at one number while charging. Before you replace anything, it helps to know what is normal and what is not. This guide explains what Apple says about battery health, what you can safely try yourself, and when the symptoms point to a battery that needs service. 1. Check Battery Health First Open Settings, then tap Battery. Tap Battery Health or Battery Health & Charging. Look at Maximum Capacity. It measures the battery capacity comp...
