Winows 10 and F secure Booster Speed up registry
I have been having major problems with my PC since Windows 10 upgrade. I am working through them one by one and now have the following. I have run the free version of Booster and it found two problems. The first is "delete unnecessary files" which works OK but the second "Speed up Registry" give me a message "Optimizing to Windows registry is not possible right now. System restart required." I am not sure what this means.
I have restarted Windows and still get the same message and reinstalled Booster from the F-Secure Safe page and the same happens. (BTW, I had to reinstall Safe following the upgrade.)
Everything worked OK until the upgrade. Can you help me please.
