How to Fix Lines on a Monitor Screen in Windows 10
Use a screenshot test, cable and port checks, monitor diagnostics, display settings, and driver rollback to pinpoint lines on a Windows 10 monitor.
If Microsoft Store opens on Windows 10 but an app will not download or install, start by restarting the PC, signing in to the Store, and checking for both Windows and Store updates. If that does not work, reset the Store cache, repair or reset Microsoft Store, then check the system time, region, and Windows Store Apps troubleshooter. These steps address the most common causes without requiring a Windows reinstall.
One important current note: standard Windows 10 support ended on October 14, 2025. The operating system still runs, but Microsoft recommends moving to Windows 11 where possible or using an eligible Extended Security Updates option if you must stay on Windows 10. See Microsoft’s Windows 10 end-of-support guidance.
A pending restart can block Store installs after Windows updates. Restart the PC first, then open Microsoft Store and make sure you are signed in with the Microsoft account you intend to use.
If the Install button is missing, the problem may not be a Store failure. Microsoft notes that an app can be unavailable because of country or region restrictions, device incompatibility, family settings, removal from the Store, or account/device authorization. Review Microsoft’s app availability and installation guidance before troubleshooting the Store itself.

Microsoft recommends checking both Windows Update and Store app updates. A Windows update does not automatically mean the Microsoft Store app itself is current.
Microsoft documents these Windows 10 steps in Fix problems with apps from Microsoft Store.


A damaged or stale Store cache can interfere with downloads. Windows includes wsreset.exe specifically for resetting the Microsoft Store cache.
wsreset.exe and select OK.This procedure is documented on Microsoft’s Microsoft Store installation support page.

If clearing the cache is not enough, use Windows 10’s app recovery controls:
Reset is the more aggressive option and can remove app data or restore the app to its default state, so you may need to sign in again afterward. Microsoft explains these recovery controls in Repair apps and programs in Windows.
Incorrect time or region settings can prevent the Store from completing secure account and licensing checks. In Windows 10, go to Settings > Time & Language > Date & time and turn on Set time automatically. If appropriate for your PC, also enable automatic time-zone detection. Then open Region and verify that Country or region matches your actual Store region.

You can also run the Windows 10 Store troubleshooter: open Settings > Update & Security > Troubleshoot > Additional troubleshooters, select Windows Store Apps, and choose Run the troubleshooter. Apply any recommended fix, restart Windows, and test the installation again.

No. wsreset.exe resets the Microsoft Store cache; it does not uninstall the apps already installed on the PC.
A short delay can be temporary, but an installation that remains stuck should not be treated as guaranteed to fix itself. Restart the PC, update Windows and the Store, run wsreset.exe, and then use Repair or Reset if the problem continues.
