Apps and Programs that Slow Down your Windows PC

We have curated a list of apps and programs that are either outdated, unnecessary or can cause potential risk to your device. Let us take a look at the list now.

Preinstalled Microsoft Apps and Games

Preinstalled Microsoft Apps and Games

Microsoft has been notoriously bundling a bunch of apps and programs that you might never use. These programs are likely to be eating up a lot of storage space, run in the background, and send your information to Microsoft so it is best to get rid of them and free up some space on your PC.

Mixed Reality, 3D Viewer, Movies and TV, Outlook, OneNote, and Windows PC Health Check are some of Windows bloatware to name a few. You can uninstall most of the Bloatware using the Debloater method mentioned above.

Preinstalled Manufacturer Apps

Preinstalled Manufacturer Apps 

If you have purchased a Laptop or Desktop from manufacturers like Acer, Dell, HP, or Lenovo then your device must have come installed with a bunch of apps and programs from the manufacturer. These apps mainly include assist or support apps that are nothing but junk and you can download most of them anytime from Microsoft Store in case you need it. So it is best to get rid of them.

Torrent Clients


Torrent clients like uTorrent have a lot of ads which makes it extremely annoying to navigate through its interface. Moreover, uTorrent bundles a crypto mining software that can end up using a lot of your system resources. If you want to use Torrent programs then you can go with qBitTorrent or Deluge.

Adobe Flash Player

Adobe Flash Player

Remember when you first opened Youtube and it prompted you to download Adobe Flash Player? Adobe Flash Player was required by browsers to play flash games, videos, and other web content. But since January 2021, Adobe Flash is retired and no longer further supported so you should uninstall it.

Microsoft Silverlight

Adobe Flash Player

Similar to Adobe Flash Player, the Silverlight plugin was used by web browsers to view web content on numerous websites. But it has long been forgotten and is not used by modern web browsers other than Internet Explorer.

Java Plugin

Java Plugin 

Java is used by very few websites nowadays and not supported at all by most popular browsers like Chrome and Firefox. So the only use case there is left for Java nowadays is if you are a Developer that requires Java. But if you are not then it is best to uninstall it.

McAfee Antivirus Software


Anti-Virus software like McAfee might have been crucial to Windows when it lacked any sort of protection from malicious programs. With Windows 10, you get a program called Windows Defender that does the same thing as other Anti Virus Software but better as it is built into Windows. And these also hog up on a lot of system resources so it is best to uninstall them.

PC Optimization and Cleaner Tools

PC Optimization and Cleaner Tools

Windows has evolved to a point that it is self-sufficient to optimize its performance. And if there is a need for improvement then you can look into a guide just like this one and do it yourself. Optimization tools and Cleaners are not quite useful and just adware to sell you their Pro version by showing fake issues in your PC.

Examples of these tools include CCleaner, MyCleanPC, and PC Optimizer Pro.

Browser Extensions

Browser Extensions

Browser extensions are separate plugins that run in the background when you are using your web browser. Although helpful, these may also end up using a lot of system resources and ram causing your system to slow down so we recommend you remove any extension that you do not find useful.

Wrapping Up: Remove App That Slow Down PC

Windows has become quite demanding when it comes to resources these days so it is best to remove any unnecessary apps and programs that may bog down the performance of your computer. If you find there are any other apps and programs that are sitting idle on your PC then we recommend uninstalling it and also clearing out temporary files from time to time.
