Speed up registry failure


Since I installed F-Secure Booster about a month ago I have never been able to get the Clean/Speed up registry function to work. All I get every time I try to run it is the following message:

Optimizing the Windows registry is not possible right now. System restart required."


I have obviously restarted the computer many times over this month that I´ve had Booster but it doesn´t help. The function tells me that there is 43% issues with speed up registry but it just wont optimize.


What can be done to correct this?


(Windows 10,  version 1511 OS build 10586.36 // Booster version

    Hi santamonica47,


    Based on the error message, the issue will either be related to Windows Updates or another program Installation that has likely failed at some point, and parts of the registry are locked. Could you please check in the Control Panel and make sure there are no outstanding Windows Updates or that there are no Windows updates that are continuously failing to be updated in your computer?

    Hi Laksh,


    No, my device is up to date with Windows Updates and has no updates that are failing.
