Computers can have issues when room becomes tight on your computer.
- Updates will not install or download
- Emails will stop
- Icons can disappear
Just to name a few.
So check how much room you have left – right click on the C Drive for Windows and go to properties.
You can then go to disc cleanup if you need to make room.
While you are in settings why not turn on Storage Sense which can help make room on your PC – instructions can be found here : Storage Sense
