Windows 10: Can't select multiple files in file explorer

Hi, I have an issue where I can't select multiple files in file explorer. This problem only occurs in the small window that web browsers give you to upload a file to a website. I also can't select a time range by clicking the titleex: all the files i downloaded today, yesterday, last week, etcThis issue isn't in the main file explorer program, so it's not a mouse issue, and it happens on more than 1 web browser, so it's not a web browser issue.It's not a very big issue, but it is quite annoying because I upload multiple files constantly and it's annoying to manually select and import every f

In File Explorer, can no longer see selected files (not hilighted)

In File Explorer, when I select a file in the list, it used to hilight so you could tell, but since recently installing Updates (January 2019) you cannot see what files you have selected. This is a problem when copying multiple files since you cannot
tell if you have all of the intended files selected or not. How do I fix this?

 

Problems selecting multiple files in file explorer

While in file explorer (fe) I start by selecting the first file, press the shift key and start to scroll down using the down arrow key in order to select multiple files - by the time I've got to the 10th file the first x files have been automatically unselected
- the x is a variable sometimes all of the above files have been unselected and not necessarily consecutive files have been unselected its totally random.

HOWEVER - if I click the down arrow key very slowly one file at a time - they remain selected.

This is a DELL laptop with the latest windows 10 (loaded laptop i7, 16gb ram, 500gb ssd etc.

Anyone encountered this?

 

Can't select multiple Microsoft files in File Explorer

I can't select multiple Microsoft files in File Explorer. I select a file and my whole computer lags / freezes. It does select eventually. I go to select while pressing shift and my whole computer freezes again and the action isn't completed. It's only Microsoft
files. I can select multiple folders and other types of files without any lagging. I just re downloaded Microsoft Office recently. Don't know if that's what caused this. I did try to delete any old Microsoft application files before re-downloading. This is
a recent issue, I downloaded Microsoft Office on a Monday and this became an issue on a Friday. I dont remember doing anything that could have caused this.

I don't know if this is connect but I got this error.



I followed the solution from here:Office error “could not create the work file” - Office. I dont
get the error anymore but I still cant select multiple MS files.

I've reset File Explorer and it's settings. Didn't work.

Thanks for the future help.
