   Warning

Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Driver Booster 3, please remove them as it may cause trouble.

An easy way to get remove these drivers is by using a restore point prior the installation.

Please remove / disable items from the startup in taskmanager
These programs could interfere with the boot process giving you trouble and increase the boot time.

Please (re)move some files to increase the free space to at least 15%.
Every partition needs at least 10-15% free space so Windows can do its thing in the background, 15% is to be on the safe side.

   Warning

Less free space could cause BSODs or other problems, because Windows cannot perform the tasks it needs to do in the background!

Please make sure your pc is configured for small dump files How to configure minidump | Windows 10 tutorial.
