Yesterday I opened Event Viewer on Windows 10 and I saw some warnings and 1 error about ESENT 455 (That error was easy to fix by putting some missing files in the right place and now it's ok). Moreover, some of the warnings said that after Windows login, the performance of the cpu drops a little bit. Which is also ok, and it's due to the undervolt I've done (It is stable I tested it with 2 programs). But today another error occured about a file called "imcontroller" that stopped working, and was due to "Lenovo System Interface Foundation". Many articles say that this may be a virus. In my case it wasn't, because I scanned it with different programs. It's just a file/thing from the Lenovo Foundation. I deleted completely Lenovo Foundation from my drive, from a hidden file called ProgramData and some last files from regedit. Now the error does not come up anymore.
My question is: is it safe that I deleted Lenovo Foundation from all of these locations?
By the way the laptop seems to have the same performance as before, if not a little bit better. But I'm worried, even tho I've read that Lenovo S. I. Foundation is pre-installed and it's a program that is optional.
