Performance
Computer takes minutes to start up
A machine that used to boot in seconds and now takes minutes is almost always loading too much at sign-in, or doing it from a failing or nearly full drive.
Read before you start
If the drive is clicking, or the machine shuts itself down during startup, back up now and stop restarting it — a failing drive can lose everything with a few more boots.
This guide is for you if
- The desktop appears, then nothing works for a minute
- The fan runs hard the whole time it starts
- Sign-in itself sits on "Welcome" for ages
Step by step
Work top to bottom0 of 6 steps done
Watch what is loading
Open Task Manager > Startup and look at the Startup impact column. Disable the chat apps, game launchers and updaters you do not need running from the moment you log in.
OneDrive, Teams and antivirus suites are the usual top three. Disabling them is reversible.
Free space on the system drive
Below roughly 10% free, Windows has no room to work and everything slows down. Clear downloads, old installers and duplicate photo folders.
Check the drive it is starting from
If the machine still has a spinning hard drive, that is the whole answer — an SSD upgrade is the single biggest speed change available for an older machine.
Task Manager > Performance shows the disk at 100% on a healthy-looking system: that is a slow drive or a failing one.
Let the pending updates finish
A machine that installs updates at every shutdown spends every startup finishing them. Leave it on and connected for an evening.
Scan for malware and unwanted toolbars
Run a full scan with the built-in antivirus, then remove browser extensions and programs you did not install on purpose.
Back up before you change anything else
If the drive is making noise or the slowdown came on suddenly, back up your files first and let us check the drive health.
A drive that is failing often shows as slow boot before it shows as errors.
