Quick fixes

Run a virus scan tool

It sounds simple enough, but a virus can cause a spike in the resource usage of many different Windows processes. If the Microsoft Store or any downloaded application is infected with a virus, you may experience high resource usage.

Windows Update

If there is an issue with the Microsoft Store, updating Windows can install any new updates to the Microsoft Store. This is especially true of major feature updates.

Uninstall the latest app

If the problem started immediately after installing a new app, delete that app and restart the computer. If this fixes the problem try reinstalling the app, as for the first time, it might not be installed correctly.

Increase virtual memory

This can help by allocating more memory to the computer. Open Start and type performance. Select Adjust the appearance and performance of Windows .

Select Adjust the appearance and performance of Windows

Select the Advanced tab and click Change under Virtual Memory .

Click Change in Virtual Memory

Uncheck Automatically manage paging file size for all drives . Select your drive and click Custom size . Set the initial capacity to the device’s RAM (in megabytes) and the maximum size to 2 times.

Disable Microsoft Store

This is a drastic but more effective solution if you’re not really using the Microsoft Store. If you use Windows 10 Professional or Enterprise, you have access to the Group Policy Editor. If you’re on Windows 10 Home, you can’t use this method, but there is a workaround.

First, to use Group Policy, press Win + R and type gpedit.msc. Click OK.

Next, choose Local Computer Policy> Computer Configuration> Administrative Templates> Windows Components> Store . Select Turn off the Store application .

Click Edit policy setting . Select Enabled and then click Apply.

If you can’t do this, you must use Registry Editor instead. If you do, be careful. Wrongly changing something can damage the system.

Open Start and type regedit. Select Run as administrator .

Select Yes when prompted.

Expand the following options:


If you don’t see WindowsStore , right-click on Microsoft and choose New> Key . Name it WindowsStore.

Right click on an empty area on the right after you select WindowsStore. Choose New> DWORD (32-bit value). Name it RemoveWindowsStore.

Create a new RemoveWindowsStore value

Right click here and choose Modify. Set the value to 1 . Reboot the computer when you’re done.

Set the value to 1

Turn the value back to 0 to reactivate the Microsoft Store, also known as Windows Store in Windows 8.

A combination of all of the methods above may be needed to correct this problem. Always backup your system before making any major changes to ensure its safety.
