Refresh, not reinstall
Many people see reinstalling Windows as the ultimate solution to a problem. While a fresh install should – in most cases – fix problems that aren’t caused by underlying hardware issues, they’re often overkill for less serious ones, particularly if your computer appears to be functioning perfectly other than for a few minor glitches.
Windows 8.1 provided a handy ‘refresh’ option, that enabled you to reinstall Windows on top of itself – it was the equivalent of a repair install from earlier versions of Windows. Programs, settings and other non-Windows files were left in place, so while Windows replaced its own files with backups from your system, everything else was – technically – unaffected.
Windows 10 removed this option, but if you think a quick refresh is all your system needs, then download the latest version of the Media Creation Tool from www.microsoft.com/ en-gb/software-download/ windows10. Launch it, accept the licence agreement and then – when prompted – leave ‘Upgrade this PC now’ selected and click Next. Wait for the latest Windows installation files to be downloaded, along with any additional updates. Finally, check that ‘Keep personal files and apps’ is selected before you click Install.
The installation process is identical to performing a full reinstall, but your apps and data will be left untouched. Note it’s a lengthy process, so be prepared to wait an hour or more depending on the speed and state of your PC.
