One of the major things that happens to be of a great help in increasing the speed of your computer is labeled as ‘clearing the cache‘. Anyway it must be remembered that it isn’t everything that contributes to increase speed, but it still does exceptionally good in some cases. Specifically in Windows 8, where you have to deal with two different kinds of environments labeled as the desktop and the Modern UI. You must get to know how to clear the cache for both of the cases mentioned above, and in the tutorial below, you will just find out how to do that. So proceed 
Tutorial to Clear Cache of Desktop Apps,Internet Explorer 10,Windows Store,Live Tiles in Windows 8
Clear Windows 8 Desktop Apps Cache
Let’s begin with the very first thing i.e. desktop. The most easiest and user friendly thing that can be used in such case is a utility like CCleaner that will help you in wiping your browser cache, thumbnail cache, font cache, DNS cache and a lot more. You have the option to clear the cache of all the browsers on your computer simultaneously with the help of CCleaner (in place of doing the whole thing manually, one by one in order).
Apart from CCleaner, you also have the option to try some manual methods (for instance the ones that were used in windows 7, if you are familiar with them). You would be glad to find out that all those methods are still workable on Windows 8. For example, if you are looking forward to clean the thumbnail cache, you have the option to use Disk Cleanup. Although, you won’t come across “Disk Cleanup” in the All Apps menu that you find, but it still exists there.
You are required to type “cleanmgr” on the Start screen, after that press Enter and in the end select cleanmgr.exe from the search results. Here, the Disk Cleanup will open and scan for files.
Once the scanning is completed, you are required to check ‘Thumbnails’ and in the end click OK.
At times, when you’re coming across browsing problems (despite the fact that your internet connection is working just fine), you probably are required to flush your DNS cache.
In order to do so, you need to open command prompt, and after that type the following command: (don’t forget the space after ipconfig)
ipconfig /flushdns
Clear Modern UI Apps Cache
There are a lot of things that you can do here. Let’s start with Internet Explorer, the Modern UI version of the browser, that is.
Clear Internet Explorer Cache
Yes, the desktop version of IE contains its own browsing history, and in the same way the Modern version has it too. For the latter one, you are required to open Internet Explorer from the Start screen.
All you need to do is Bring up the Charms bar (one of the multiple ways to do that is to move your mouse into the bottom-right corner of the screen, probably one of the simplest thing to do) and after that click Settings and then select ‘Internet Options’ from the menu that appears.
Click the Delete button under ‘Delete Browsing History’ to do just that.
Clear Windows Store Cache
Let’s now proceed to another Modern UI app. What do you think about resetting the Store cache? In order to do so, you are required to press Win key + R to bring up the Run Window. After that type “WSReset.exe” and in the end press Enter.
The Store app will open, and you’ll come across the message that is shown below.
Clear Search History
If you are used to using the Search function of the Charms bar on very regular basis, you must consider deleting the search history for sure. If you want to do so, you are required to launch the Charms bar, and after that select Settings > PC Settings.
You can Select Search from the left pane, and then click the ‘Delete history’ button that is present below ‘Search history’.
Clear Live Tiles Cache
One last thing but not to be ignored that you might consider doing is clearing up the live tiles cache. You have the option to easily do this whenever you notice that the live tiles are failing to be ‘live’.
All you are required to do is on the Start screen, simply hit Win key + C or just scroll to the bottom-right corner in order to open the Charms Bar and after that select Settings > Tiles.
Under ‘Clear personal info from my tiles’, you will see the ‘clear’ button, click it.
You’ll notice that all your live tiles will be reset to default as soon you are done with this procedure.
These were few methods to clear cache on windows 8. I hope they helped you. Enjoy
