.Net Runtime Optimization Service CPU Load

post #1 of 13
Thread Starter 
Yo.

At start I do want to say I made a search on Google and this forums as well, but didn't find anyone who would provide an answer that would work for me.

The problem here is simple. For over a month now, the .NET Runtime Optimization Service has been "compiling the update" every single day, using about 40% of my CPU (for the rig check the sig). I tried re-installing it, fixing it, forcing to work faster through command prompt, using the clean-up tools, waiting for it to finish (obviously) even in safe mode... I can't forcibly close it, it doesn't show up in services and it likes to work along the "Windows Store App service", which sometimes appears, sharing the CPU usage by half (meaning both services use about 20%. Sometimes another .NET Optimization service starts up as a 64-bit application, again never going above that around 40% threshold of CPU usage. May not seem much, but I would prefer the CPU to have its idle temps of 30, rather than 50 because of the load, along with obviously a lot less space on the CPU power.

I'm at the point where the only thing left to my knowledge is to format the PC, however with Windows 10 soon releasing, I prefer to do it then rather than now. So my question is this. Is there anything I can do to fix this without resorting to formatting? Any help at this point is highly appreciated.

Try running CMD in Administrator,

Type SFC /scannow,

Uninstall .Net and Reinstall.

I imagine you've got some corrupt OS files causing a redundancy or something.

Started the SFC scan.

As to re-installing the .Net, did that already. Removed it completely, used a clean-up tool to make sure, installed it back, same thing. Driving me crazy -_- If it would be indeed corrupt OS files, then... ehh, can't Win 10 come out sooner? xD

You should reinstall it again if it finds an errors with the SFC. While probably not always the best thing to do it would be bad to use a registry cleaner to check for errors.

Yeah it found corrupt files but it was unable to fix some of them. Gonna try re-installing it once more. And also used the CCleaner to check for registry errors few times already. But I'll re-do it again since at this point it won't hurt anyway.

Edit: Uninstalled it without installing back and... it popped up anyway. Though now it closed after few minutes, meaning behaved as it normally should. Gonna install it back, will see how it does this time. Still strange that appeared after being uninstalled o.O

Edit2: Installed it back, now two of those service popped up immediately (32 and 64-bit). Gonna see if it's gonna take "few minutes" and disappear as it should or the problem will stay.

You can always check to make sure the .Net you've obtained is the right one for example 8.1 usually installs it for you when you launch something dependent of it.

If SFC failed to repair a few things it could mean there are some seriously corrupt files. You could perform a directory service restore without losing your data just your programs from,

To restore your PC.
Swipe in from the right edge of the screen, and then tap the Gear(Settings). Tap Change PC Settings. Tap PC and Recovery. Tap Recovery. Choose Refresh your files.

WARNING! If you do not have your personal files kept in the appropriate directory it could disappear, verify it's stored where it should. Also if your system is beyond corrupt it may ask for the disc to continue recovering.

Downloaded the latest .NET from Microsoft specifically for the 8.1 64-bit, so I doubt there are any issues in that department.

Well, time for the "Refresh" option, as it's translated in my language version xD If that won't work, I assume the only thing left to do would be formatting? Or are there still some options depending on the outcome?

Depending how long you've utilized your OS for or what traumas it's experienced there usually is no better cure. However I do bear a concerned mind that you could have a virus or physical problem contributing to the system file corruption. Then again you've got an OCZ for an SSD.

Finding that disk with Windows 8.1 proves to be harder than I imagined. May have to resort to downloading one from Microsoft.

Did a full scan with Norton, so that's done. And I really don't get why people have such a bad opinion about OCZ SSD's. This is my 2nd one from OCZ (first was 60GB) and I never had any problems with corrupt data till this thing happened. Other than this it runs very smoothly without any issues, and considering my bad luck with hardware, I can't imagine that I get the "miraculously working examples".

Downloading from Microsoft is easy.
