Haha, in fact, after cracking the system, there is no effect at all, only psychological effect. Now almost no third version of the virus has been found. Even if there is, signing or not is just a threshold, and the security of the third edition system is still worthy of rest assured.

If the landlord really wants to remove the crack, just delete CProfDriver_SISX.ldd and installserver.exe in the folder C:\sys\bin.
