Win 10 process kill "access denied" & undeletable file

Greetings,


i've encountered the following problem a few times already:


I try to kill a crashed process with the Taskmanager. It gives me a "Access denied" error.


Here the long version:


I started a game called "Borderlands The pre sequel" (happened to some other games aswell)

The process "Launcher.exe" started but the gui didn't appeared. Now i tried to end the task with the taskmanager. Nothing happens.

Next step was killing the proces itself using the taskmanager. Error: "Access denied".


-I made sure to use the taskmanager as admin (started it via admin powershell).

-I checked ownership of the file and security settings.

-I tried to kill the process with the cmd.

-I checked the process que , it's waiting for no other process.

-i tried to unlock the file with "Unlocker" and "Deadlock". it says sucessfully unlocked. i was able to remove the file "Launcher.exe" but the process remains active.

-The process seems inactive, 0% cpu usage, 1,8mb ram usage.


To finally end the process i had to restart the PC.

Problem 2


Undeletable file


I set a programm called "Netspeed Monitor" to create a databank with the usage of my network. At some point I deactivated it again, and the nsm.db (Net Speed Monitor.db) file remained on my desktop. Now i wanted to remove the file, but windows tells me, that it's active in a process. I closed the Netspeed Monitor (and made sure the process is closed). Still the same problem.

I used DeadLock to check what process is locking that file. Appearently it's the Explorer.exe.


I ended the explorer.exe and DeadLock confirmed that the file is no longer locked. I deleted it and restarted the explorer.exe. The file simply reappeared and is locked again. This file is there for weeks already, so please do not suggest to do a restart.


Im grateful for anything that helps.
