How to Speed Up a Slow Windows PC (No Tech Knowledge Needed)

1. If your PC takes forever to start or feels laggy, it's usually not broken — it's just overloaded.
2. These steps clean it up in about 20-30 minutes, no technical skill required

Method 1 — Disable unnecessary startup apps

Startup apps (programs that open automatically the moment you turn on your PC) are one of the biggest reasons a PC feels slow to begin with. The more of them running quietly in the background, the longer everything takes.

1. Press Ctrl + Shift + Esc to open Task Manager
2. Click the Startup apps tab
3. Look at the Startup impact column (shows how much each app slows down your boot)
4. Right-click any app you don't need immediately (games, chat apps, media players) and select Disable
5. Leave your antivirus and any work-required apps enabled

Method 2 — Free up space with Storage Sense

Storage Sense is a built-in Windows tool that automatically deletes temporary files (leftover junk files apps create and never clean up on their own) and empties your Recycle Bin.

1. Press Windows key + I to open Settings
2. Click System
3. Click Storage
4. Turn on Storage Sense
5. Click Run Storage Sense now

Method 3 — Turn off background apps you don't need

Background apps keep running even after you close them, quietly using up memory (RAM — the part of your PC that holds everything currently in use) and processing power.

1. Open Settings
2. Click Apps > Installed apps
3. Click the three dots next to an app you rarely use
4. Click Advanced options
5. Under Background apps permissions, select Never

Method 4 — Reduce visual effects

Windows uses animations and transparency (see-through menu effects) to look nice, but these use extra graphics power that older PCs don't have to spare.

1. Press Windows key + R
2. Type sysdm.cpl and press Enter
3. Click the Advanced tab
4. Under Performance, click Settings
5. Select Adjust for best performance
6. Click Apply, then OK

Method 5 — Run a quick malware scan

Malware (harmful software that runs secretly on your PC) can silently eat up your processor and slow everything down, even if nothing looks wrong on screen.

1. Open Settings
2. Click Privacy & security
3. Click Windows Security
4. Click Virus & threat protection
5. Click Quick scan

Method 6 — Install pending Windows updates

Updates often include performance fixes, not just new features. A PC stuck on an old update can run worse than it should.

1. Open Settings
2. Click Windows Update
3. Click Check for updates
4. Install anything available, then restart your PC

Method 7 — Restart your PC properly (not just Sleep)

Sleep mode pauses your PC without clearing memory. Over days of sleeping instead of restarting, leftover clutter builds up in RAM.

1. Click Start
2. Click the Power icon
3. Click Restart (not Sleep or Shut down)

If it's still slow after all this

If you've done every method above and your PC still feels slow, the cause is likely hardware, not software — most commonly a hard drive instead of an SSD (a much faster type of storage) or not enough RAM. At that point, a hardware upgrade is the next step, not another software fix.
