While Windows 10 is full of brand new features to help you get the best possible experience, I wanted to take a look under the hood and see if it was vulnerable to the same performance hogs as its predecessor Windows 8.1.

I am of course talking about system slowdowns due to program load. While it may not be noticeable at first, the more programs you install, the more slowdown creeps up on you. Why is that the case? And what can we do about it? This blog has answers.

Daily slowdowns

More installed programs means more processes and services going on in the background. Don’t believe us? Using a professional analysis tool called Windows Assessment Toolkit, we measured the average resource consumption while working with Microsoft Office both under the load of 150 applications (see benchmarks below for more details) and on a device optimized with AVG PC TuneUp.

The increased activity doesn’t just have an impact on performance, but on the total lifespan and power consumption, as well. PC TuneUp tools like Program Deactivator, Startup Manager, Uninstall Manager or Turbo Mode can all help you decrease this activity and make your PC run smooth again.

Hard disk thrashing & fragmentation issues

Background applications and 3rd party software can be responsible for a lot of unnecessary hard disk activity, even though you’re not actively using the programs. Of course, this also affects the total lifespan of all hardware components.

Then there’s the fragmentation phenomenon which occurs daily: creating, copying, moving and deleting files causes hard disk data to be scattered all over the place. This in turn reduces overall performance. PC TuneUp's Drive Defrag restores perfect order to your hard drive while speeding up file access, boot times, and program launches.

Less disk space

Windows® and your programs constantly save log files. For instance, it creates "Most Recently Used“ lists and keeps temporary data on your hard disk – but “forgets” to delete them. Over time, that leads to critical disk space issues and problems with you applications. PC TuneUp's Disk Cleaner removes all of these types of files.

Battery life & power consumption issues

Even Windows 10 doesn’t really turn off unnecessary hardware on your laptop when you’re on the road. Nor does it sufficiently adjust to what you’re doing. This is where PC TuneUp's Economy Mode and Flight Mode comes in. They increase battery life and reduced power consumption, allowing you to work longer while saving on power bills, thanks to an array of power-saving techniques such as smart CPU power control, power saving modes for your devices, and the deactivation of power-hungry Windows features.

Windows 10 has its weak spots, just like Windows XP, Vista, 7, and 8. One of them is the registry and the way it’s built: through daily usage of a PC or laptop, the registry can become cluttered with errors, such as pointers to non-existent startup items, file types, programs, settings, or hardware components no longer in use. This could result in some of the following problems:

  • Invalid startup entries: These leftover entries may cause startup errors.
  • Incorrect file type references: Causing files to be opened by the wrong program.
  • Incorrect uninstaller entries: Such entries lead to errors when installing or uninstalling applications.
  • Missing fonts: Causes fonts to not show up in programs.
  • Invalid ActiveX and COM component pointers: May lead to error messages when running applications.
