When is a good time to reinstall Windows? Well, no matter how well you look after your computer, you’ll undoubtedly notice that, after some time, it’s performance and reliability is no longer up to scratch. This is normal on any computer after months or years of use, even if you regularly run maintenance tasks and uninstall unused programs on a regular basis. Sooner or later, your computer is inevitably going to get bogged down with junk software and minor reliability problems which can, collectively, cause major system slowdowns and other problems. It’s probably time to reinstall Windows and get your computer up and running properly again as though you just took it out of the box.

There’s a whole load of reasons why your computer slows down after a time. Of course, regularly running Disk Defragmenter and Disk Cleanup will help to keep it working optimally for longer, but the time will eventually come when you should reinstall Windows. The system will eventually get clogged with problematic files and data caused by things such as botched system and program updates, programs which did not uninstall correctly or remains of malicious software which you thought you removed. When you reinstall Windows, you correct all of these problems and doing so will ensure that you get rid of any traces of malicious software or redundant data. It’s one of the most effective ways of optimizing your PC and it’s free too.

Knowing when to reinstall Windows shouldn’t be hard. As soon as you are finding that the overall performance and reliability of your computer has dropped significantly, then is the time to reinstall Windows. Likewise, if essential system services such as System Restore are no longer working reliably or if your computer takes far longer to start up than it should, then it’s probably time to reinstall Windows.

For novice users and first-timers, to reinstall Windows may seem like a formidable task. Fortunately, you don’t really need any expertise or experience. It does take a long time though, especially since you will need to reinstall all of your programs, updates, drivers and files again afterwards. Before you begin, it’s essential to make doubly certain that you have backed up all of your data, ideally on another partition or hard disk in your computer. Once you’ve made all of the necessary preparations, you’ll be ready to reboot your system and go through the Windows Setup utility.
