AppData/Local/Temp getting filled up with many copies of same folder

terrybollinger · 31 Aug 2016

I daily clean out temp files, both with CCleaner and manually. At random times my Win10 Home system randomly inserts insane megabytes of Win10 dll's into the folder [C:\Users\<me>\AppData\Local\Temp], and fails to clear them on reboot.

There is no plausible way that this kind of insane replication of executable code serves any useful purpose, especially given its randomness. So, it's either a very dumb Microsoft caching strategy gone bad, or some kind of outright error, or malware. I'm trying to figure out the pattern for it.

Does anyone out there already know the specific process that is going insane?

You need to find out either by specific analysis (e.g. sysinternals procmon (free) - a more technically demanding route- and identify from its captured log what specifically is creating those files, or by elimination (see my previous post).

Don't necessarily expect someone to say 'it's this, and this is what you have to do to stop it' - you'll need to do some analysis.

So there are two possible routes:
a. analytical using procmon.
b. by elimination, in the hope of reaching a situation where it doesn't happen and working back.

It is a permissions problem on a cleanup task usually from the windows 10 upgrade. Here is how to stop it.

Run Task scheduler

expand "Task Scheduler Library", then Microsoft, then Windows, then find and click on "Disk Cleanup". Look for "Silent Cleanup Task" on the top pane, you will see that it has failed in the "Last Run" comments. Disable the task and your problem will go away
