Sometimes, updates to Windows can prevent Maple (and other programs) from working properly. To determine which updates were installed recently, please do the following:
- Open the Start menu.
- Select Settings.
- Select "Update & security".
- Click on the "Update history" link.
You will now see a list of the most recently installed updates, which will include a serial number of the form KB1234567. Searching the serial number online will take you to the official Microsoft page, which may contain a list of known issues (and corresponding fixes). The "Update history" window should also contain a link to the "Uninstall updates" window, which will allow you to uninstall any updates you wish to remove.
