Reinstalling Windows can be frustrating for many reasons. It tends to be a very time-consuming process, requiring you to download and install all your apps, updates, drivers, and in some cases even restore data from a backup. There’s a lot that needs to be done for a computer to get back to a fully working condition. But it is necessary sometimes, as performance tends to degrade over time, so your best bet is to make the process as seamless as possible.
