Is your PC booting slower than ever? Do apps lag or freeze at the worst moments? Over time, junk files, startup clutter, and registry errors can drag PC performance to a halt. So, how to speed up a PC? The good news is—you don’t need to be a tech expert to fix it. Just follow these simple steps below to bring your system back up to speed.
In most cases, PC slowdowns aren’t caused by a single issue but a mix of factors. Pinpointing these underlying causes is the first step; here are some common ones:
Too many startup programs launch automatically when your PC starts.
Temporary files, cache, and leftover data accumulate and take up valuable disk space.
Too many applications continue running in the background.
Outdated software and drivers lacking important updates lead to slower operation.
A nearly full system drive can limit Windows’ ability to run efficiently.
Excessive visual effects look nice, but consume system resources.
Power-saving modes may limit CPU performance and reduce overall speed.
Potentially malicious programs run silently and drain system resources.
Based on these common causes, here are some quick, built-in fixes you can use to speed up PC effortlessly:
Step 1. Press Ctrl + Shift + Esc to launch Task Manager.
Step 2. Navigate to the Startup tab.
Step 3. Select the programs you don’t need at startup and click Disable in the bottom-right corner. You can still launch them manually anytime.
If your Windows PC is running low on storage, it can lead to slower performance. Here are a few simple ways to speed up PC for free:
Step 1. Search for Disk Cleanup from the Start menu and open it.
Step 2. Select the main drive you want to clean up (usually C:), then click OK.
Step 3. Check and tick the files you want to delete.
Step 4. Click OK, then click Delete Files to confirm.
Step 1. Go to Start menu > Settings > System > Storage.
Step 2. Turn on the Storage Sense feature to let Windows auto-delete unnecessary files.
Overinstalling programs can consume storage space and run background processes that slow down your PC. Here’s how to remove unused ones:
Step 1. Go to Start > Settings > Apps > Apps & features.
Step 2. Scroll through the list, select the unnecessary program, and click Uninstall.
Step 1. Go to Settings > Privacy > Background apps.
Step 2. Disable apps you don’t need running in the background. The fewer background processes, the better your CPU and memory performance will be.
Step 1. Type Adjust the appearance and performance of Windows in the Start menu.
Step 2. Open it to access Performance Options.
Step 3. Select Adjust for best performance to disable all visual effects. Or, select Custom to choose your preferred settings.
Step 4. Click Apply.
If you’re using a traditional hard drive (HDD), fragmentation can slow it down. If you have a solid‑state drive (SSD), fragmentation isn’t needed, but optimization still helps.
Step 1. Still, type Defragment and Optimize Drives in the Start menu.
Step 2. Select the drive and click Optimize.
How to speed up the PC? Keeping your programs and software up to date is also an important step. The process is easy: go to Settings > Update & Security > Windows Update, and install the latest updates for improved performance and stability. For a faster approach, try IObit Driver Booster. It scans your system for outdated, missing, or corrupted drivers and lets you update them all with one click—saving you the hassle of manual searching and installation.
Step 1. Go to Settings > Update & Security > Windows Security > Open Windows Security.
Step 2. A new window will pop up. Click Scan now under Virus & threat protection.
Step 3. Click Quick scan to check for common threats.
Step 1. Press Windows + S, search for Control Panel, and open it.
Step 2. Click Hardware and Sound > Power Options, and select Power Saver.
Step 3. Alternatively, click Change plan settings next to the selected plan to customize settings, such as sleep time and screen timeout.
A simple restart can effectively resolve temporary system slowdowns. It refreshes system resources, clears temporary files from memory, and closes unnecessary background applications.
Although Windows includes built‑in performance tools, they often require manual effort and technical know‑how.
