Why this matters
A slow computer costs time every day. Most slowdowns come from too many apps starting automatically, a nearly full drive, pending updates or ageing hardware. Working through these checks usually brings a noticeable improvement.
What you'll need
- Your Windows computer
- An administrator account for some steps
Step-by-step instructions
Step 1
Restart properly
Select Start, Power, then Restart. "Shut down" on modern Windows can keep the system in a hibernated state, while Restart fully clears memory.
Step 2
Disable unnecessary startup apps
Press Ctrl + Shift + Esc to open Task Manager, select "Startup apps", and disable anything you do not need when Windows starts.
Step 3
Install pending updates
Go to Settings, Windows Update and install available updates, including driver updates under Advanced options, Optional updates.
Step 4
Free up storage
Windows slows down when the system drive is nearly full. Aim to keep at least 15–20% free.
Step 5
Run a security scan
Open Windows Security, Virus & threat protection, and run a Quick scan. Malware can cause slowdowns.
Step 6
Check your browser
Close unused tabs and remove browser extensions you do not recognise or need.
Step 7
Consider hardware
If the computer still uses a mechanical hard drive, upgrading to an SSD is the single biggest speed improvement. 8 GB of RAM is a practical minimum for business use; 16 GB is better.
Summary
Trimming startup apps, keeping Windows updated and freeing up space fixes most slow computers. If it is still slow, the hardware may be due for an upgrade.
