Is it safe to disable ngentask.exe?

[amvt285]

Hello,

After the recent window's update I've notice this file eating up my cpu% and after researching this problem through I'm not the only one having this issue. I tried all possible solution I could find but it did not work. I even went to task scheduler and let this run through for hours on end with no solution. I'm wondering is this ok to completely be disabled without harming my system? If anybody could shed some light on this issue it would be greatly appreciated.

I found your post on malware site from a week ago. I had this running for a while last week but its since stopped, it shouldn't continue to run though

The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. Ngen.exe creates native images, which are files containing compiled processor-specific machine code, and installs them into the native image cache on the local computer. The runtime can use native images from the cache instead of using the just-in-time (JIT) compiler to compile the original assembly.

MS LInk

the recent windows update was (potentially) a new version of win 10 so it may need to rebuild the applications. Its also possible its a bug as they seem to sneak in with version updates.

DID you try a SFC/DISM run and see if it fixes any corrupted files? as if they corrupt, the .net might be stuck on its rebuild

right click start
choose run...
type winver and press enter
If you are on 1703, try this:

right click start button
choose powershell (admin)
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:
Repair-WindowsImage -Online -RestoreHealth
SFC fixes system files, DISM cleans image files, re run SFC if it failed to fix all files and restart PC

If you on 1607 or earlier, the instructions are slightly different

right click start button
choose command prompt (admin)
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:
DISM /Online /Cleanup-Image /RestoreHealth and press enter
SFC fixes system files, DISM cleans image files, re run SFC if it failed to fix all files and restart PC

Hello,

Oh yes, about Sophos products. After following your instructions and scanned twice this is what I got. Is there any other way to fix these corrupt files?

Thanks!

hmm, you second person telling me dism doesn't work today...

try this
search cortana for command prompt
right click search result and run as admin
copy/paste this into same window
DISM /Online /Cleanup-Image /RestoreHealth and press enter. then rerun SFC and restart PC

Now if it asks for source, do this:
Download a copy of the win 10 iso from Here - create ISO by telling it you want to make DVD - and then mount that ISO in file explorer (see Here) and then copy paste the below command into command prompt (admin)

DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess
Where "X" is the drive letter where the ISO is located. Simply change the "X" to the correct drive letter
