Sometime files gets corrupted or for whatever reason come up missing. like what happened, the other day when I was working on a friends computer. An error occurred for the task manager “The service cannot accept control messages at this time.”
To resolve these kind of issues, you can use what is known as SFC/SCANNOW, or the system File Checker. What this program does, is search your operating system, and if it finds a file that needs replacing due to corruption, it will replace it for you.
In order for this work, you will need the operating disc, for that particular OS, if you don’t have one, you can always borrow one for this operation.
if you are using Windows Xp, and you want to get to Command prompt click start >all programs >accessories, >command prompt >run as administrator, i have provided a link below:
If your running Vista or Windows 7 click on the start button, in the search field type in Command Prompt, when you have the link, Right click and choose “Run as Administrator. For Windows 8, go to the Start Menu, Desktop, hit the Windows Key + C, then type in the search field “Command Prompt” Right-Click “Run as Administrator” Once getting to the Command Prompt, you should see C/ from here then type sfc/scannow and press the enter key,
This will probably take a little time, so you might want to go and do something for a while. after it is finished it will let you know if it found anything. It will usually tell you what was found. Once done, go ahead and close the window or if your a new techie, just type Exit, tap the power button and the computer should shut off. Then go and restart the system. Hope this helped. Putting God First, God Bless.
