There is a big difference between installing a pile of software in each system for more than half a year. Tools like Kingsguard generally do not delete built-in systems or commonly used software plug-ins and information. Under normal circumstances, the system will not become "slow", but the user's software function may be affected because the software function modules or information that have not been excluded in advance are cleaned up.

Handling suggestions:

1, it is suggested to see if the guard has any functions such as operation recovery and cancel the modification of the registry and plug-ins.

Or if the system restore protection is not turned off, directly restore to the restore point for reuse.

In fact, if you use win7, don't change the system configuration casually with optimization software, except for the customization of some users' usage habits, the performance improvement is limited. The effect of XP optimization is obvious.

2. If a lot of garbage is cleaned up, but the network is affected, it may be that the network driver is affected after cleaning up the plug-in.

You can try to uninstall the network card in hardware management, search the hardware again, and reconfigure the local connection information after finding the network card.

3. If only a specific software is affected, you can reinstall the latest version of the software, so that all its plug-ins and the like will be repaired.

Finally, if you have used any network acceleration software, reinstall it.

After all the above suggestions are processed, it is best to restart and test the effect.
