Anonymous 2018-06-15T12:59:59+00:00 Hi, I'm Diego Rios, an Independent Advisor willing to help other Microsoft customers. Regarding your question, I suggest you to follow the troubleshooting methods listed below: Change the display settings: Sometimes, the issue may be caused due to incompatible display settings. Changing the settings or restoring them to the default settings might solve the issue for you. Press Windows key once 2, Select Settings from the start menu Click System In the System window, select the Display tab in the left hand panel (if it isn’t already). In the display tab, change the size of your text using the bar on the right pane. This should be the bar under the Change the size of text, apps, and other items: 100% (Recommended) You can choose any percentage except for the 175%. Setting the bar to 175% is known to cause the issue. After selecting the font size, click Ok and check if the error persists. Close Programs like Anti-viruses: Press CTRL, SHIFT and ESC key simultaneously (CTRL + SHIFT + ESC). This should open the Task Manager. In the Task manager, click the Processes 4.. The Processes tab has a number of columns, look at the Description column and find the process that is related to the anti-virus. It should have a name for the anti-virus you have. 5.Select the anti-virus process from the list and click End Process (bottom right corner). Click Yes when prompted for confirmation. Once done check if the problem is solved or not. If you are still experiencing the problem then make sure there aren’t any other security related programs running in the background. There might be programs other than the security programs that might be causing this issue. Try to turn off as many applications as you can to see if the problem is solved.
