Windows filename suddenly gets selected again while renaming it

Solution 1:

Hello from the year 2020.

I found out that it is a Google Drive sync issue (the product was renamed to “Backup and Sync from Google” meanwhile).

You can test it yourself:

1. Click on the Google Drive icon (in the system tray), hit the tree dots and select "Pause".
2. Go to Windows Explorer and rename the files.

You will see that the file renaming bug is not happening anymore.

Solution 2:

It sounds like you're using a laptop and accidentally touching the touchpad. Try disabling it. Or if you have the feature, set it to ignore spurious activity.

Solution 3:

I found that stopping Carbonite solved the problem, for me. It seems that however they hook into Windows Explorer was causing the whole filename to be re-selected shortly after starting to rename a file.
