Speed up a slow PC | Windows help

A slow Windows PC costs time and patience. These steps often bring noticeable performance back.

A slow Windows PC costs time and patience. These steps often bring noticeable performance back. This guide walks you through common fixes step by step. If it does not work or you prefer professional help, Leftclick AG in the Basel region is here for you.

Step by step

  1. 1

    Check startup programs

    Open Task Manager with Ctrl+Shift+Esc, go to Startup and disable programs you do not need right away.

  2. 2

    Free disk space

    Go to Settings, System, Storage and remove temporary files. Windows needs free space for updates and paging.

  3. 3

    Install updates

    Check Settings, Windows Update for pending updates. Missing patches can affect performance and stability.

  4. 4

    Limit background apps

    Close unused programs and review Settings, Apps for background permissions.

  5. 5

    Restart the PC

    A clean restart ends stuck processes. If the PC stays sluggish, the cause is often deeper.

When DIY is not enough

If these steps do not help, you are unsure, or several devices in your business are affected, Leftclick AG can take over troubleshooting. We work via remote support or on-site in the Basel region and find the root cause without guesswork.
