A slow Windows PC can turn a five‑minute task into a full‑blown patience test. At PC Revive, the good news is that most speed issues come from a handful of fixable culprits. This guide walks you through quick wins first, then deeper tune‑ups, and finally sensible hardware upgrades. Do them in order and you’ll feel the difference. For more quick guides, browse our blog.

Step 1: Rule out the simple stuff

Restart the PC. It clears stuck processes after updates or long uptimes.
Close heavy apps you aren’t using. In the taskbar, right‑click apps and quit.
Check free storage. Aim for at least 20–25% free space on your system drive (usually C:). Low space slows Windows features like paging and updates.

How to free space fast:

  • Empty Recycle Bin and delete large downloads or old installers.

  • Press Win+R, type cleanmgr, run Disk Cleanup, and select temporary files.

  • Move photos and videos to an external drive or cloud storage. If things are still sluggish, see our guide to fixing a slow PC and common causes of a slow startup for quick wins.

When space is freed, reboot and retest speed before going further.

Step 2: Tame startup apps

Too many programs launch at boot and hog resources. For a hands‑off cleanup, our tune‑up service trims bloat without breaking essentials.

Windows 10/11: Press Ctrl+Shift+Esc → Startup tab. Right‑click non‑essentials → Disable. Keep drivers, security, and sync tools; disable updaters, chat clients, or launchers you don’t need immediately.

Tip: If you’re unsure about an entry, disable it temporarily. You can re‑enable later if something you rely on stops auto‑starting.

Step 3: Update Windows, drivers, and apps

Updates fix bugs, improve performance, and close security holes that can slow a PC.

  • Windows Update: Settings → Windows Update → Check for updates.

  • Drivers: Update graphics, chipset, and network drivers via Device Manager or the manufacturer’s utility (Intel Driver & Support Assistant, NVIDIA/AMD apps).

  • Apps: Update browsers, office suites, and creative software.

Reboot after major updates. Keeping software current prevents bottlenecks; here’s why software updates matter.

Step 4: Hunt down resource hogs

Open Task Manager (Ctrl+Shift+Esc) and check the Processes tab.

  • Sort by CPU, Memory, and Disk.

  • If a process you don’t recognize is constantly high, right‑click → Open file location. If it looks suspicious, scan for malware (see Step 7). If usage spikes alongside crashes or odd noises, review these PC failure warning signs before it worsens.

On laptops, also check Battery settings → Battery usage by app to catch background apps chewing through power and performance.

Step 5: Clean browser bloat

Web browsers can balloon with extensions and cached data.

  • Remove extensions you don’t use.

  • Clear cache/cookies in your browser settings.

  • Consider enabling Efficiency Mode (Edge) or closing heavy tab groups.

  • If the browser still drags, export bookmarks and try a full Reset settings to defaults. While you’re at it, brush up on tips to avoid computer viruses to keep browsers snappy.

Step 6: Lighten visual effects and indexing

Windows looks pretty out of the box, but those animations add up.

Adjust performance options:
Search “Adjust the appearance and performance of Windows” → choose Adjust for best performance or keep Show thumbnails and Smooth edges of screen fonts for a balanced look.

Search indexing:
Open Indexing Options → Modify → remove folders you don’t need indexed (large archives, backups). Rebuild the index if results are slow.

Step 7: Scan for malware and junkware

Unwanted software can hijack resources and clog startup.

  1. Windows Security (built‑in): Settings → Privacy & Security → Windows Security → Virus & threat protection → Quick scan.

  2. On‑demand second opinion: Use a trusted malware scanner for a one‑time check.

  3. Uninstall shady programs: Settings → Apps → Installed apps; remove toolbars, “PC cleaners” you never installed, or duplicates.

If pop‑ups or redirects return after cleaning, repeat scans in Safe Mode and reset your browser. If threats keep reappearing, follow our checklist on signs of malware or book our virus cleaning.

Step 8: Fix system files and drive errors

Corruption slows everything.

System File Checker (SFC):
Search cmd, right‑click Command Prompt → Run as administrator → run:

sfc /scannow

If errors persist, run the Deployment Imaging command, then SFC again:

DISM /Online /Cleanup-Image /RestoreHealth

sfc /scannow

Check the drive:

Open File Explorer → right‑click C: → Properties → Tools → Check. Repair if prompted. Before running heavy repairs, take five minutes to back up to an external drive.

Step 9: Optimize power and background services

Power plan:

Settings → System → Power & battery → Power mode → choose Balanced or Best performance when plugged in. On desktops, open Control Panel → Power Options and try High performance if available.

Background apps:

Settings → Apps → Installed apps → per‑app permissions. Turn off background execution for apps you rarely use.

Step 10: Manage storage like a pro

Turn on Storage Sense (Windows 10/11) to automatically remove temp files, old recycle items, and previous Windows versions after big updates.

Consider moving game libraries and large video projects to another drive. If you’re constantly running out of space, these hardware upgrades can save time and frustration. Keep the system drive lean and mean.

Step 11: Temperature and dust check

Heat throttles performance.

  • Place the laptop on a hard surface; avoid beds and couches.

  • Blow dust from vents with short bursts of compressed air.

  • If temps spike under light use, a professional internal cleaning and fresh thermal paste can restore performance. For everyday care, try these laptop maintenance tips.

Step 12: Smart upgrades that make a huge difference

1) Solid‑State Drive (SSD): If you’re on a mechanical HDD, moving Windows to an SSD is the single biggest speed boost—faster boot, near‑instant app launches, quicker file operations.

2) More RAM: If you regularly sit at 80–90% memory usage, an upgrade to 16 GB for general use (or more for creative workloads) will reduce swapping and stutter.

3) Wi‑Fi adapter or Ethernet: Old wireless cards can bottleneck speeds. A modern adapter or a wired connection can stabilize downloads and meetings.

When upgrading, back up first and choose reputable parts compatible with your system. If you’d like help, our PC upgrades, including SSD replacements and RAM upgrades, are quick and data‑safe.

Step 13: When a refresh makes sense

If the PC is still crawling after cleaning and scans, consider a Repair Install of Windows (in‑place upgrade that keeps files and apps) or a Reset this PC (you can keep personal files, then reinstall apps). Both options remove deep‑seated software issues. Back up before you proceed.

Quick checklist (print‑worthy)

  • Keep 25% free space on C:.

  • Disable non‑essential startup apps.

  • Update Windows, drivers, and apps monthly.

  • Audit Task Manager for CPU/RAM/Disk hogs.

  • Trim browser extensions and cache.

  • Run SFC/DISM, check the drive.

  • Use Storage Sense.

  • Keep it cool and dust‑free.

  • Upgrade to an SSD and add RAM if needed.
