A computer that takes forever to open programs, lags when you switch between tabs or freezes during basic tasks is not just annoying. It is costing your business time every single day. The good news is that most slowness is caused by a few common problems that are easy to fix.
Check your available storage
When your hard drive is nearly full, everything slows down. Windows needs free space to manage temporary files, run updates and keep things moving. If your drive is more than 85 percent full, performance will suffer.
To check, open Settings, click System, then click Storage. You will see a breakdown of what is using space on your drive. Pay attention to the bar at the top. If it is close to full or showing in red, you need to clear some space.
Clean up temporary files
Windows accumulates temporary files, old update files and cached data over time. These can safely be removed.
In the same Storage settings screen, click Temporary files. Windows will scan and show you what can be removed. Tick the categories you want to clear, such as Temporary files, Delivery Optimisation files and Thumbnails. Then click Remove files. This alone can free up several gigabytes.
Empty your Downloads folder
Most people download files and never move or delete them afterwards. Over months, the Downloads folder can grow to several gigabytes of installers, documents and files you no longer need.
Open File Explorer and go to your Downloads folder. Sort by date and review what is there. Delete anything you no longer need. Move important files to a proper location like your Documents folder or OneDrive so they are backed up.
Uninstall programs you do not use
Old software that you installed once and never used again still takes up space and sometimes runs background processes that slow things down.
Go to Settings, then Apps, then Installed apps. Sort by size to see which programs are taking up the most space. If you see something you do not recognise or no longer use, uninstall it. Be careful not to remove anything your business relies on. If you are unsure about a program, leave it and ask your IT provider.
Close programs you are not using
Every program you have open uses memory. If you have 20 browser tabs, Outlook, Teams, Excel and a few other things all running at once, your computer is dividing its resources between all of them.
Get into the habit of closing programs and tabs you are not actively using. If your computer still feels sluggish, press Ctrl + Shift + Esc to open Task Manager. Click the Memory column to sort by memory usage and see which programs are using the most. If something is using a large amount and you are not using it, close it.
Move files to OneDrive
If your business uses Microsoft 365, OneDrive can help free up local space without losing access to your files. OneDrive has a feature called Files On-Demand that keeps your files available in File Explorer but only downloads them to your device when you open them. This means files are stored in the cloud and only take up space locally when you actually need them.
Right-click any file or folder in your OneDrive and select Free up space to remove the local copy while keeping it accessible from the cloud.
When to get help
If your computer is still slow after following these steps, the issue may be deeper. Failing hardware, malware, insufficient memory or an ageing machine that simply cannot keep up with modern software are all possibilities. Recloud monitors and maintains business devices so problems like these are caught and resolved before they cost your team hours of lost productivity.
