The temp folder provides work space for programs. Yes they can be deleted. We suggest that you follow the steps provided by Sangeeta Sarkar on how to delete Temp files on this

Win 10 - Folder and files in C:\Windows\Temp\NC5pBB

Thank you for the suggestions.

To answer your question as to what happened when this was first seen,

• updated Win10 with the anniversary update
• my antivirus notified about a C:\Windows\Temp\tmp00007eb1\tmp00000000 file, which was quarantined and subsequently I deleted through the antivirus

Now I see that there is a C:\Windows\Temp\tmp00007eb1\tmp00000000 file there, which the antivirus says is clean and I can delete, but I cannot delete the C:\Windows\Temp\tmp00007eb1\ folder!

From your suggestions:

1. Run the sfc /scannow command

It came back with:

W i n d o w s R e s o u r c e P r o t e c t i o n d i d n o t f i n d a n y i n t e g r i t y v i o l a t i o n s .

2. Rebooted

I was able to delete the NC5pBB folder and all its contents.

I was not able to delete the tmp00007eb1 folder

I could delete the tmp00000000 file

3. Did a clean boot

I was able to delete the NC5pBB folder and all its contents.

I was not able to delete the tmp00007eb1 folder

I could delete the tmp00000000 file

4. Did a regular boot

The NC5pBB folder came back, with a bunch of contents similar to the original post.

I was able to delete the folder and its contents.

The tmp00000000 file came back and I was able to delete it.

I was not able to delete the tmp00007eb1 folder.

Do you have any other suggestions?

Thank you!
