Your Windows PC Suddenly Slow?
The Free 10-Minute Tune-Up

Your Computer Didn't Wear Out — It Filled Up

“My computer got slow” is one of the most common reasons my phone rings in Portage County. Over months, a Windows PC quietly picks up passengers — programs that launch themselves at startup, updates waiting half-finished, temporary files piling up, a browser dragging twenty tabs. No single one of them is the problem. The pile is the problem.

The internet's answer is a minefield of paid “PC cleaner” and “registry cleaner” apps — $30 to $60 a year for jobs Windows already does free. You don't need any of them. In my experience, the free tune-up below fixes or dramatically improves the majority of “suddenly slow” computers. Here it is, step by step.

Step 1: Restart — and Why “Shut Down” Doesn't Count

Here's a genuine surprise: on modern Windows, Shut down and Restart are not the same thing. A feature called Fast Startup makes “Shut down” take a shortcut, so weeks of accumulated clutter never actually clears out. Restart is the real fresh start. Click the Start button, then the power symbol, then Restart — not Shut down. Let it settle for two or three minutes before judging the speed. This alone fixes an astonishing amount. One real Restart a week keeps most computers feeling fresh.

Step 2: Let Windows Finish Its Updates

A computer that's halfway through an update can crawl for hours, and one that's stuck mid-update can crawl for weeks. Go to Start › Settings › Windows Update. If updates are waiting, click Install (or Restart now) and let it run — coffee break, not a crisis. One rule: never turn the computer off while an update is showing percentages. Interrupting an update is one of the few ways to turn a slow computer into a broken one.

Step 3: Trim the Startup Apps

1. Right-click the Start button and choose Task Manager (or press Ctrl + Shift + Esc).
2. Click the small menu button (three lines) at the top-left, then click Startup apps.
3. You'll see each program with a Status and a “Startup impact” rating.
4. Click a program you don't need at startup, then click Disable. Start with anything rated High impact.
5. Keep security software, backup tools like OneDrive, and audio/touchpad helpers. Disable printer “helpers,” music apps, chat apps, and game launchers — they open in seconds when you actually want them.
6. Disabling does NOT uninstall or delete anything — the program just waits to be opened instead of barging in at breakfast. If you miss one, come back and click Enable.

Step 4: Give the Disk Some Breathing Room

Windows uses spare disk space as its workbench — a stuffed drive slows everything. Go to Settings › System › Storage, click Temporary files, and let Windows list what's safe to clear. One critical warning: uncheck “Downloads” if it's listed — that means your Downloads folder, with your tax PDFs and family photos, not junk. Then click Remove files. While you're on the Storage page, flip Storage Sense to On — it's Windows' built-in housekeeper, and it keeps this cleanup happening on a schedule without you. If the drive is still stuffed, my Storage Full guide covers the bigger job.

Don't Forget the Browser — Where “Slow Computer” Often Really Lives

• Every open tab is a little running program. Close tabs you're done with — bookmark the keepers (Ctrl + D) instead.
• Check your extensions: in Edge or Chrome, click the puzzle-piece symbol, then “Manage extensions.” Remove coupon bars, “PDF converters,” and search “enhancers” you didn't knowingly install.
• If typing a search suddenly uses a site you've never heard of, an extension hijacked it — remove the extension and set your search back in the browser's settings.
• Fully close and reopen the browser now and then. Browsers accumulate clutter across days just like Windows does.
• If websites crawl but folders and programs open fast, the problem may be your internet, not the PC — my Home Wi-Fi guide helps you tell the difference.

The Page That Saves You Money: Skip “PC Cleaner” Apps

• Those scary free “scans” that find 2,000 “errors” are theater — they count harmless leftovers by the thousand to frighten you into paying.
• “Registry cleaning” doesn't speed up modern Windows — even Microsoft doesn't support registry cleaners, and a bad registry edit can genuinely break things.
• Everything legitimate they do, Windows already does free: temporary files, Storage Sense, startup apps, antivirus, and driver updates through Windows Update.
• Already paying for one? Check your card statement for auto-renewing “cleaner” or “driver updater” charges, uninstall the program, and cancel. If it gets sticky, bring the statement to a visit and we'll untangle it together.
• And never call a phone number from a pop-up that says your computer is infected or slow. Real Windows warnings never include a phone number — that's a 100% reliable scam tell.

Still Slow After All That? The Honest Possibilities

Sometimes it's physical: an old-style spinning hard drive or too little memory. Check in 30 seconds — right-click Start › Task Manager › Performance › Disk, and it says HDD (the slow, spinning kind) or SSD (the fast kind). An SSD swap is the single most dramatic speed upgrade there is, often under $100 in parts, with your files kept in place. And if your machine still runs Windows 10 — which lost regular free support in October 2025 — my Windows 10 End of Support guide walks through the options calmly. I fix computers; I don't sell them, so you'll get the “is it worth it” answer straight.

Why I wrote this

“My computer got slow” might be the sentence I hear most often in this job — and the fix I do on those visits is mostly the free routine in this guide. I'd rather you have it in writing. I write these guides as printable handouts so the checklist can live next to the computer, and if you'd rather do the whole thing with company, that's a normal $99 visit with a 30-day follow-up included. Either way, please don't give another dime to a “PC cleaner” app. — Bill
