Windows applications remain stable for a long time, rarely showing significant drops. Boot times may increase slightly as more background programs load, but performance stays consistent for most users. Frequent updates aren't necessary unless you notice a decline. It's not a matter of personal preference—consistent performance is what matters.
It will clear out some space. That's roughly all there is to it.
Windows applications remain stable for a long time, rarely failing within just a few months. Generally, programs don't lose functionality, though the operating system can. This varies based on user habits. Often, unnecessary software is added without being removed. Some tools are included by default, like how Oracle once bundled a toolbar with Java downloads. Many users install programs they don't need and then forget about them. Certain applications are set to run automatically at startup, such as Acrobat Reader Updater. Old app or driver setups can create conflicts that a reset might fix. Clearing disk space usually improves performance.
They are incorrect information being passed around. I just want to clarify some things. Windows itself and programs, on an HDD, doesn't slow down over time (ignoring the fact that newer version of Windows and programs, which tend to add features, MAY affect performance depending on the system specs and the feature in question, and if it is one that runs on the back, or just some added option that can be executed when needed). What tend to happen with system with HDDs, is fragmentation and data scattering. So fragmentation, I think we all know what it is, and why it happens, if not, let me know and I'll explain. So you can defrag the HDD, and that is fine, but that doesn't solve data scattering, As the HDD just write at the first available slot without looking forward (as they are super slow, even if you have a 10,000RPM HDD), but your data can, over time scatter as you defrag it. So let's say, Windows needs to load file A, B, and C. They might be in a row from each other. Great! HDD head doesn't need to move. But after updates, adding data, fragmentation happens, and due to defragmentation they end up being: C [some other data] A [some other data] B... now the HDD head needs to go all over the place to get the data.. and those are just 3 files. The fix is to do either A clean install with the latest version of Windows, programs and games to reduce it. or Deep Defragmentation. An example is to use something like O&O Defrag, and do a Complete/Modifiy defragmentation to sort the files. Doing this may take 8h+ if you have lots of data and and fragmentation or data scattering is pretty bad. Of course, you also want to make sure your SATA controllers set to AHCI mode and not IDE, to make sure you get the full performance of SATA on your side, and enjoy NCQ which can drastically improve performance as this diagram shows: A - No NCQ B - NCQ in action An SSD is a great way to render all this to a non-existing issue. That said you do want an SSD with DRAM cache chip, and always set your SATA Controller to AHCI mode.
It might perform less efficiently. The reason is that each user updates drivers, addresses issues, and refines settings gradually. Starting from a factory reset places you at the beginning of the process, meaning your computer isn’t set up according to your preferences. Programs you rely on for speed won’t be installed, and useful tools may be missing, forcing you to install alternatives each time you double-click an unknown file and forget to set up the necessary programs. As a result, your work tends to be slower, especially if you're more experienced. If you mainly install Windows without much activity, resetting the OS can give you the impression of a faster system. It offers mostly automatic suggestions, but it’s still an engaging experience—reinstalling or cleaning your OS regularly every month, week, or day can keep things fresh. This approach helps protect your storage until it fails.
