Your computer isn’t slow because it’s old.
It’s slow because Windows ships with 15+ hidden settings draining your speed by default.
Change these 9 and it will run like new again.
Most people have never touched them.
Thread 🧵
1/ Kill Startup Bloat
Your PC loads dozens of apps every time you turn it on. Most of them sit in the background eating RAM and doing nothing.
Ctrl + Shift + Esc → Startup tab → right-click anything you don't need immediately → Disable
Keep your browser and antivirus.
Disable everything else. Spotify, Discord, OneDrive, Teams, Skype, Adobe, Zoom. They all launch faster from a click than from running in the background 24/7.
This single change cuts boot time in half on most machines.
2/ Turn Off Animations
Windows wastes processing power on smooth window transitions, fade effects, and shadow rendering. All cosmetic. All draining your CPU.
Search "performance" in Start → Adjust the appearance and performance of Windows → select "Adjust for best performance" → Apply
Your desktop will look slightly more basic. Your PC will feel noticeably faster within seconds.
3/ Stop Background Apps
Apps run in the background even when you close them. Windows allows this by default.
Settings → Privacy & Security → Background apps → turn off "Let apps run in the background"
Or scroll through the list and disable them one by one. Leave only the ones you actually need running when you're not using them
4/ Purge Temp Files
Windows stores temporary files that pile up for months. Old updates, cached data, error reports. They eat storage and slow everything down.
Settings → System → Storage → Temporary files → check everything → Remove files
Or type %temp% in the Start menu → Select All → Delete. Skip any files that are "in use." This alone can free up 5 to 20GB.
5/ Switch Power Plan
Windows defaults to "Balanced" which throttles your CPU to save energy. If your PC is plugged in, there's no reason for this.
Search "power plan" in Start → Choose a power plan → select "High performance"
If you don't see it: click "Create a power plan" on the left side → select High performance
Laptop users: use High performance when plugged in, Balanced on battery.
6/ Turn Off Search Indexing
Windows constantly scans and indexes every file on your drive so search results appear faster. On older machines this uses massive CPU and disk resources for a feature most people rarely use.
Search "services" in Start → scroll to "Windows Search" → right-click → Properties → set Startup type to "Disabled" → Stop → Apply
You can still search your files. It just takes a few extra seconds instead of running constantly in the background.
7/ Free Up Disk Space
When your drive is over 80% full, Windows slows down significantly. It needs free space for virtual memory, updates, and temp processing.
Settings → System → Storage → turn on Storage Sense
Storage Sense automatically deletes old temp files, empties the recycle bin, and removes old downloads. Set it to run every month.
Also uninstall apps you haven't opened in 6 months.
Settings → Apps → Installed apps → sort by date → uninstall what you forgot existed.
8/ Disable OneDrive Sync
OneDrive syncs files to Microsoft's cloud constantly. Every document, every photo, every desktop file. All uploading in the background while you're trying to work.
Click OneDrive icon in taskbar (bottom right) → Settings → Account → Unlink this PC
If you still want OneDrive, at least pause syncing while you work: OneDrive icon → Pause syncing → pick 2, 8, or 24 hours.
9/ Restart Weekly
Most people never fully shut down their PC. They close the lid or hit sleep. Windows accumulates memory leaks, cached processes, and background errors that only clear on a full restart.
A real restart once a week clears everything. Not sleep. Not hibernate. Start menu → Restart.
If your PC has been running for weeks straight, this alone might fix the lag
That's a wrap!
