Why Windows 11 PCs Are Suddenly Running Slow (And What You Can Do About It) – 1/26/2026
If your computer has felt slower than usual lately, you’re not imagining it. Across the Twin Cities, we’ve been seeing a surge of customers bringing in Windows 11 desktops and laptops that were “fine last month” but now take forever to boot, lag during simple tasks, or freeze when opening programs. This is one of the hottest and most current computer repair issues right now because it affects everyday users, students, and small businesses alike—especially after recent updates and background security changes.
At Twin Cities PC Repair, we help customers in Bloomington, Richfield, Edina, Burnsville, Eden Prairie, and the greater Minneapolis–St. Paul area get their systems running fast again without losing important files.
Why Your Windows 11 PC Is Slowing Down Right Now
There are a few common causes we’re seeing repeatedly in local repair appointments:
1. Background Updates and “Silent” Maintenance
Windows 11 updates don’t just install once and disappear. Many updates trigger background tasks like indexing, system cleanup, security scans, and driver updates. On older PCs (or even newer ones with limited storage), this can cause random slowdowns, high CPU usage, and long boot times.
2. SSD Storage Filling Up
A PC with a 256GB or 500GB SSD can feel blazing fast—until it hits a storage wall. When your drive gets close to full, Windows struggles to manage temporary files, paging, and system processes. We commonly see machines with less than 10–15% free space, and that alone can make the system feel “broken.”
3. Startup Programs Taking Over
Many popular apps install auto-start services that run the second you turn on your PC. Some are helpful. Many are not. The result is a computer that takes 5–10 minutes to become usable after booting. This is extremely common with systems that have been used for a couple years without a tune-up.
4. Malware and Browser Hijackers (Still a Big Problem)
Even in 2026, malware hasn’t gone away—it’s just gotten sneakier. We’re seeing more cases of:
Fake “Microsoft support” pop-ups
Browser redirects and unwanted extensions
Credential-stealing spyware
Adware that slows everything down
These threats can make your PC crawl, even if you have antivirus installed.
5. Overheating and Dust Buildup
Minnesota weather swings are rough on electronics—especially if a PC is kept near a vent, heater, or dusty area. Over time, dust blocks airflow and your CPU overheats. When that happens, the computer “throttles” performance to prevent damage, causing lag and stuttering.
Quick Fixes You Can Try at Home (Before You Bring It In)
If your computer is still usable, try these steps:
Restart the PC (not shut down—restart forces updates and memory cleanup)
Check storage space and delete large files or uninstall unused apps
Run Windows Security scan and remove suspicious browser extensions
Update drivers (especially graphics + Wi-Fi)
Make sure your PC is ventilated and not clogged with dust
If these don’t help, it may be time for a professional diagnosis.
When It’s Time for a Repair Shop Instead of DIY
Some slowdowns are caused by deeper issues that require hands-on troubleshooting, such as:
A failing SSD or hard drive
Corrupted Windows system files
Bad RAM (random freezes and crashes)
Overheating requiring internal cleaning and new thermal paste
Virus infections that keep coming back
A proper computer tune-up can often restore performance without replacing the whole machine.

Why Fileless Attacks Are Hard to Spot (But Still Detectable) – 12/18/2025
Twin Cities Cybersecurity Awareness for Home & Small Business Users
Cyber threats targeting Minnesota homes and small businesses are becoming more sophisticated, and one of the most dangerous trends we’re seeing across the Twin Cities is the rise of fileless attacks. These stealthy attacks don’t behave like traditional viruses, making them harder to detect—but with the right tools and awareness, they are still preventable.
What Is a Fileless Attack?
A fileless attack is a cyberattack that does not install malicious files on your computer’s hard drive. Instead, it uses trusted tools already built into Windows—such as PowerShell, Windows Management Instrumentation (WMI), or web browsers—to execute malicious commands directly in system memory.
Because nothing suspicious is saved to disk, many older antivirus solutions never see a warning sign.
Why Fileless Attacks Are Especially Dangerous in the Twin Cities
Local businesses and residential users are prime targets because attackers know:
Small businesses often lack enterprise-level security
Home users may rely on basic antivirus software
Many systems are left unpatched or misconfigured
In the Twin Cities area, we frequently see fileless attacks delivered through:
Phishing emails pretending to be local vendors or service providers
Fake Microsoft or Windows security alerts
Compromised websites that inject malicious scripts
Why Fileless Attacks Are Hard to Detect
No files to scan Traditional antivirus tools look for malicious files. Fileless attacks operate entirely in memory, leaving almost no footprint.
They abuse legitimate Windows tools PowerShell, command-line utilities, and system processes are trusted by default, allowing attackers to hide in plain sight.
They mimic normal system activity Because the behavior looks “normal,” these attacks can remain active longer without triggering alarms.
They often rely on user interaction A single click on a malicious link is often all it takes—no download required.
What Can Fileless Attacks Do?
Once active, fileless malware can:
Steal passwords and saved browser credentials
Monitor keystrokes and screen activity
Spread across connected devices or office networks
Create backdoors for future attacks
We’ve seen Twin Cities clients affected without realizing anything was wrong—until systems slowed down, accounts were compromised, or data was stolen.
How Fileless Attacks Are Still Detectable
Modern cybersecurity no longer relies only on file scanning.
Behavior-based endpoint protection Advanced security tools detect unusual PowerShell activity, abnormal memory usage, and suspicious system behavior.
Network traffic monitoring Unexpected outbound connections or data transfers to known malicious servers are strong warning signs.
System logging and threat detection Improper privilege escalation, unauthorized commands, and unusual login behavior can all reveal fileless threats.
User education Most fileless attacks still start with phishing. Awareness is one of the most effective defenses.
How Twin Cities Users Can Reduce Risk
Keep Windows, browsers, and applications fully updated
Use modern, behavior-based security software
Be cautious with emails claiming urgency or local relevance
Avoid using admin accounts for everyday tasks
Schedule regular professional security checkups
Final Thoughts
Fileless attacks are one of today’s most advanced cyber threats—but they are not invisible. With the right protections in place, Twin Cities home users and small businesses can stay secure and avoid costly breaches.
If you’re unsure whether your system is properly protected, proactive security checks are far less expensive than recovery after an attack. If you have any questions, please email me HERE!
