Any Windows computer eventually starts to run slowly, and your intuition tells you it’s a hardware issue. It’s time to upgrade the processor, add RAM, or install a faster SSD. However, very often, a PC slows down not because of weak hardware, but because of software clogs. The best way to restore your system to its former speed is to address the most problematic issues: startup, background applications, and a clogged storage drive. You don’t need to be an expert to do this—it can all be done using standard Windows tools.
1. Startup—what starts without your knowledge.
Many programs add themselves to startup during installation. As a result, instant messengers, game launchers, music players, cloud storage, and updaters all launch simultaneously after you log in. Not only do these applications slow down your system startup, but they also continue to run uselessly in the background, eating up RAM. The solution is simple: go to the startup settings and disable everything you don’t need immediately after turning on your computer.
Here’s how (there are two ways to do this):
Via Windows Settings: Win + I → “Applications” → “Startup” → radio buttons next to programs.
Via Task Manager: Ctrl + Shift + Esc → “Startup Applications” tab → right-click on the program → “Disable.”
Which programs can be safely disabled? Game launchers (Steam, Epic Games, Battle.net), music services (Spotify), instant messengers (Telegram, Discord), printer and scanner utilities, and various update managers. Antivirus software, driver panels (NVIDIA, AMD), and backup systems are best left enabled.
2. Background applications that hide in the tray and processes
. Even if a program isn’t added to startup, it can still run in the background. Utilities you installed for testing and then forgot about are especially prone to this. They hang around in the system tray (the area near the clock) or in the process list, quietly using resources. The goal here is not to block everything, but to remove only those you definitely don’t use every day.
How to do it:
Open the Task Manager (Ctrl + Shift + Esc) and go to the “Processes” tab. Find programs that you don’t need to run constantly. Click on the unnecessary one and select “End task.”
Look in the system tray: click the ^ arrow to reveal hidden icons. Right-click each unnecessary icon → “Exit,” “Close,” “Exit,” or “Quit” (or something similar).
To prevent these programs from returning to the system tray, go to their own settings and disable the following options: “Run at system startup,” “Run in the background,” and “Leave the icon in the tray.”
Don’t close processes with unfamiliar names—many of them are system processes. Focus only on what you have established yourself and what you are familiar with.
3. Freeing up disk space
The less free space on your system drive, the harder it is for Windows to manage the paging file, cache, and temporary data. Old updates, thumbnails, temporary files, and other unnecessary data also accumulate on the drive. Cleaning up your computer won’t make it super-fast, but it will noticeably reduce the feeling of sluggishness when any action requires a pause.
What you need to do manually (once):
Go to “Settings” → “System” → “Storage” → click “Temporary files.” Windows will scan your drive.
Check the boxes for “Temporary files,” “Thumbnails,” “Recycle Bin,” “Windows Update Cleanup,” and everything else (although you shouldn’t touch “Downloads” in this list—it might contain files you need from earlier). Click “Delete files.”
To automatically maintain cleanliness, enable “Storage sense” on the “Storage” page. Customize the frequency of temporary file deletion and recycle bin emptying. You can also choose to delete files from your Downloads folder that you haven’t accessed for more than a month. Once configured, the system will take care of things automatically.
Conclusion:
This kind of optimization won’t replace a hardware upgrade if your computer is truly outdated. But sometimes it can transform a slow and annoying PC into a user-friendly and responsive one. Start with startup, then clean up background processes and storage—the results will be noticeable immediately.
