If your PC takes an age to become usable after you switch it on, the culprit is often a long list of programs quietly launching themselves in the background. Each one nibbles away at your RAM and CPU before you've even opened a browser. The good news is that trimming this list is one of the quickest, safest ways to make an old or budget PC feel noticeably faster, and it takes only a few minutes.
Key takeaway: Disabling non-essential startup programs in Task Manager can shave many seconds off your boot time and free up RAM without removing anything from your computer.
Windows 10 and 11 both keep a running list of every program registered to start automatically, along with an estimate of how much it slows down your boot. You don't need any extra software to manage this – it's all built in.
How to view and disable startup programs
- Right-click an empty area of the taskbar and choose Task Manager (or press Ctrl+Shift+Esc).
- Click the Startup apps tab on the left (in Windows 10 it's simply labelled Startup). If you only see a simplified window, click More details first.
- Look at the Startup impact column – anything marked "High" is worth reviewing first.
- Click on a program you don't need running the moment you log in (examples: Spotify, Skype, a printer's status monitor, a game launcher) and click Disable.
- Repeat for each non-essential entry. Leave your antivirus, graphics drivers (e.g. NVIDIA/AMD/Intel tray tools) and anything you genuinely use every single day switched on.
- Restart your PC and time how long it takes to feel responsive – you should notice a difference straight away.
You can also reach the same list via Settings > Apps > Startup in Windows 11, which lets you toggle each app on or off with a simple switch and shows the same impact rating.
Before you start: Don't disable your antivirus, firewall, or any driver-related utility from your laptop manufacturer (battery or touchpad tools, for instance) unless you're certain what it does – these are best left alone.
Going further with the System Configuration tool
For older desktop-installed software that doesn't appear in Task Manager, you can also check the classic System Configuration tool. Press Windows key + R, type msconfig and press Enter, then open the Services tab, tick "Hide all Microsoft services" and review what's left. This is a more advanced area, so only disable something here if you recognise the name and are confident it's safe to turn off.
Tip: If you're not sure what a program does, a quick web search of its exact process name (shown in Task Manager) will usually tell you whether it's safe to disable.
Why this makes such a difference on older hardware
On a PC with a mechanical hard drive or only 4-8GB of RAM, every extra background process competes for the same limited resources that Windows itself needs during startup. Fewer programs racing to load at once means the disk and CPU can focus on getting your desktop ready, rather than juggling ten things simultaneously. It's often the single biggest free performance win available to owners of budget or ageing laptops.
| Program type | Typical impact | Safe to disable? |
|---|---|---|
| Music/chat apps (Spotify, Discord) | Medium-High | Yes, open manually when needed |
| Cloud storage sync (OneDrive, Dropbox) | Medium | Only if you don't rely on auto-sync |
| Antivirus | Low-Medium | No, leave enabled |
| Printer/software helper tools | Low-Medium | Usually yes |
Frequently asked questions
- Will disabling a startup program uninstall it?
- No. Disabling only stops it from launching automatically; the program stays installed and you can still open it manually whenever you like.
- Can I re-enable a startup program later?
- Yes, just return to the same Startup apps list and click Enable. Nothing is lost by toggling it off and on again.
- Why do some programs reappear at startup after I disable them?
- Some software resets its own setting after an update. If this keeps happening, check the program's own settings menu for a "start with Windows" option and turn it off there too.
