If this is a desktop computer the operating system does a hard shutdown when the power goes out. File of programs which were running at that time could have been damaged. I would suggest running sfc /scannow. This should be run before you run the MiniToolBox as this could skew the results.
The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.
Click on the Start
, then type in cmd
in the Search programs and files
cmd will appear in Programs above, right click on it, then click on Run as administrator.
If you are prompted for an administrator password or for a confirmation, enter the password, or click Allow.
A page similar to the one below will open.
Type in sfc /scannow and then press Enter to start the scan.
If the scan finds no integrity problems in the first portion of the scan it may stop, if it does not restart within five minutes type in exit and press Enter to stop the scan.
