I deleted Bing Search, after which Windows doesn't let me restart it.
I click on restart and then it gives me the error message that I'm missing the osloader.exe file?
I then have to click through the error messages before it can finally restart.
PS. I don't have a back-up disk
In fact, your problem may not be cause by osloader.exe, and it is likely that the system was infected with the virus, resulting in the system's core file being modified.
osloader.exe is a very important system file which is responsible for loading the system kernel files and drivers.
In addition, osloader.exe file has an output function called BlLoadImage which can load the executable program into memory, and at the same time determine whether the original file was modified.
If your system kernel file has been modified, or the version is wrong, there will be some error messages.
The normal software is not to modify the system core files, so generally your system is likely destroyed by the virus. It is best to use anti-virus software to have a thorough detection.
