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 Your Computer Is Slowing Down (and How to Fix It Before It Gets Worse) – 11/24/2025
Whether you use your computer for running your business, online learning, gaming, or simply everyday browsing, one thing is universally frustrating: a slow, laggy machine. Over time, even powerful systems begin to lose their snap. In this week’s newsletter, we’re diving into one core topic that affects nearly every customer who walks through our doors:
The Hidden Reasons Your PC Slows Down — and What You Can Do About Each One
A slow computer rarely has a single cause. Instead, it’s usually a combination of software clutter, aging components, and missed maintenance. Here are the most common issues we diagnose every week at Twin Cities PC Repair.
1. Too Many Startup Programs
Most PCs have dozens of apps quietly running the moment you turn them on—slowing everything from boot time to basic performance. Many of these programs sneak in as “helpful assistants” but end up draining memory for no reason.
Fix: Disable unnecessary startup apps through Task Manager (Windows) or Login Items (Mac). Better fix: We can run a full startup optimization to remove bloat safely and cleanly.
2. Outdated or Failing Hardware
Hard drives wear out, RAM becomes insufficient, and older processors struggle with modern software demands. If your PC is 4+ years old, hardware may be a major contributor.
Fix: Upgrading to an SSD or adding more RAM often produces instant improvements. Best fix: Bring your device in for a hardware health check—we’ll test everything and recommend the most cost-effective upgrades.
3. Background Software You Don’t Even Know You Have
Hidden processes, unused apps, and even corrupted system services eat away at performance. This includes preinstalled “bloatware” and background update services.
Fix: Uninstall unused apps and run system cleanup tools. Safer fix: We perform full system tuning without risking critical OS files.
4. Fragmented or Corrupted Storage
Traditional hard drives (HDDs) slow dramatically as data becomes fragmented. Even SSDs can develop performance issues when near capacity.
Fix: Free up space, defragment HDDs, and run disk health checks. Professional fix: We scan drives for errors and optimize them safely—preventing data loss.
5. Malware & Unwanted Browser Extensions
This is more common than most people realize. Even “safe-looking” apps or extensions can track you, hijack browsing, or throttle performance.
Fix: Run a reputable antivirus scan and remove suspicious extensions. Best fix: Let us perform a deep malware scan—not just surface-level cleaning.
6. Skipped System Updates
Updates aren’t just for new features—they patch security holes and improve performance. Ignoring them can lead to instability and slowdowns.
Fix: Enable automatic updates for Windows, macOS, drivers, and apps (especially browsers!). Hands-off fix: We offer update management and routine tune-ups for businesses and home users.
