Why Your Computer Is Slow in 2025 (The Real Reasons)

Windows 11 updates, too many startup programs, junk files, and old hard drives are killing performance. Here’s what actually works—no fluff.

Step 1: Run a Full Cleanup (Free & Paid Tools I Recommend)

First thing I do for every client:

• Free option: Windows built-in Storage Sense + Disk Cleanup
• Pro option (what I actually use): CCleaner Pro—removes 10–30 GB of junk in minutes

Step 2: Upgrade to an SSD (Biggest Speed Boost Ever)

If your computer still has a spinning hard drive—this is 90% of the problem.

Best budget SSDs I install for clients in 2025:

• Samsung 870 EVO 1TB – $89
• Crucial MX500 2TB – $139 (my #1 recommendation)

Step 3: Best Antivirus That Doesn’t Slow You Down

Most antivirus software makes computers slower. These don’t:

• #1: Norton 360 – lightweight + identity protection
• #2: Bitdefender Total Security—the fastest scans I’ve ever seen
