Technology has never been more accessible. With thousands of online tutorials and powerful AI tools available to everyone, it’s easier than ever for employees to try solving IT issues on their own.
While that independence can be helpful in some situations, it has also created a new category of IT risk.
In 2026, many of the biggest IT problems we see aren’t caused by hackers, outages or system failures. They’re caused by well‑intentioned employees attempting their own “quick fixes.” What starts as a simple and harmless troubleshooting step can quickly snowball into a much bigger (and more expensive) issue.
Here are the most common IT mistakes we’re seeing this year — and what businesses can do to prevent them.
This one I equate to going to the doctor about a medical problem and telling him, “Well, Google said….” One of the most common scenarios we encounter starts with a user saying:
“I watched a YouTube video and tried to fix it myself.” STOP RIGHT THERE!
While YouTube can be a fantastic learning platform, many tutorials:
Are outdated
Apply to completely different environments
Skip critical security steps
Assume technical knowledge the viewer may not have
When users attempt to apply those fixes to a business environment, things can go awry quickly. We’ve seen YouTube‑inspired fixes result in:
Deleted configuration settings
Disabled security protections
Modified system permissions incorrectly
Installed unsupported software
Newly created duplicate or broken system policies
What started as a simple troubleshooting issue often requires undoing multiple layers of changes before the original problem can even be addressed — costing the business far more in time, money and downtime.
Another growing trend we’re seeing is users relying on artificial intelligence (AI) tools to diagnose or fix IT issues.
AI can be extremely helpful when used properly. Tools from companies like Microsoft, OpenAI and Google have made technical guidance easier to access than ever before. However, AI-generated answers are not always correct.
Sometimes the instructions are incomplete. Sometimes they are outdated. And occasionally they can be completely wrong.
Because AI systems generate responses based on patterns rather than true understanding, they can produce answers that look correct but contain dangerous mistakes. These are called hallucinations.
Without proper technical review, following those instructions can lead to serious consequences.
A colleague recently shared a real-world example that perfectly highlights the risks of blindly trusting AI-generated solutions.
While working on a solution within Microsoft 365, they used an AI tool to help generate a script to automate part of the process. They already understood what needed to be done and how to approach it, but leveraging AI seemed like an efficient way to speed things up.
For the most part, the approach worked. The AI quickly produced a usable script. But during a routine review, one line immediately stood out.
The script included a command that would have deleted all mailboxes recursively across the entire tenant.
Had that script been executed without careful validation, it could have caused catastrophic data loss across the organization. Fortunately, the issue was identified before anything was run.
This example underscores an important reality: AI can be a powerful assistant for technical work, but it should never replace human judgment, expertise and thorough review.
Another mistake we frequently see is users attempting quick fixes that bypass security controls.
Examples include:
Disabling multi-factor authentication to “test something”
Sharing admin or saving credentials in a system to speed up troubleshooting
Granting overly broad permissions to applications
Creating temporary access rules that are never removed
These shortcuts might solve an immediate problem, but they often introduce long-term security risks that can expose the organization to cyber threats.
Security controls exist for a reason and bypassing them without proper oversight can create vulnerabilities that attackers exploit.
Employees often feel comfortable troubleshooting their own laptops or home networks. But business environments are far more complex.
A change that might be harmless on a home computer could have far-reaching consequences in a corporate environment that includes:
Shared infrastructure
Identity management systems
Compliance requirements
Integrated business applications
What works on a personal laptop may break critical services across an entire organization. This is why most cyber insurance policies include provisions on change management and the restriction of administrative rights for individual users.
There’s a reason we’re seeing these issues more frequently in 2026.
The combination of easy access to online tutorials, AI-powered assistants, increasingly complex IT environments and trying to save money by doing it yourself has created a situation where users feel empowered to attempt technical fixes without fully understanding the impact.
While curiosity and initiative are valuable, IT systems require careful planning, testing and validation before changes are made.
The goal isn’t to discourage learning or curiosity.
Platforms like YouTube and modern AI tools can be helpful for understanding technology.
However, when it comes to business systems, security controls or anything involving configuration changes, the safest and most cost-effective approach is simple: call your IT team first.
A quick IT review can prevent a “simple fix” from turning into a major outage.
Technology in 2026 is powerful — and so are the tools employees now have at their fingertips. Yet with that power comes responsibility.
In many cases, the biggest IT mistakes we see aren’t caused by malicious actors; they’re caused by good intentions combined with incomplete information.
Before attempting a major system change based on a tutorial or AI-generated instructions, it’s always worth asking one simple question: Is this something that should be handled by an IT professional?
Making that call early can prevent small issues from turning into major problems.
If your team frequently encounters technical issues or wants guidance on safely using AI and modern IT tools, working with an experienced managed service provider can make all the difference.
Our team helps businesses troubleshoot problems quickly, implement secure solutions and ensure that technology works for your organization, not against it.
