what are the commands to check all drivers and windows files to be intact , if there are any?

I don't think there is such a command.

If you think your drivers are out of date or there is a problem, you should go to the hardware manufacturers WWW site and look for any updates there.

If you think you are having a driver problem and not sure what to do about it, you should describe your problem, why you think there is a problem and ask for some help if you can't figure it out.

What you should NOT do is run an kind of online scanning tools that claim to check all your drivers and update of  fix them for a fee.

These sites and scanners will ALWAYS report that your drivers are out of date that that your system is in serious trouble and if you follow their advice, you will probably end up with the wrong drivers and then they will want your money to fix it.  Then when they have your money, they will not fix it and then your system will be in serious trouble.

Pay no attention to these online driver scanning tools that offer to check your drivers - they are only after your money.

Finally, is is usually NEVER a good idea to accept any hardware driver updates from Microsoft Updates.  Microsoft does a poor job of figuring our what drivers are needed for your system and will often send you the wrong drivers if you accept them.

If Microsoft Update offers you a hardware driver, it is best to just refuse that driver update and choose the option that tells Microsoft Update to never offer you that driver update again.

Here is a simple "experiment" you can perform using the rundll32.exe file that may help you understand what sfc /scannow does and what it does not do:

Rename or just delete your c:\windows\system32\rundll32.exe file so it is "missing".

rename rundll32.exe  ---->  rundll32.xxx

If you have booted normally, almost before you can blink, the "missing" rundll32.exe file will be quickly and silently replaced with the copy from the dllcache folder.  That is Windows File Protection in action and you will see something like this in the Event Viewer System log:

Event Type:    Information

Event Source:    Windows File Protection

Event Category:    None

Event ID:    64002

Description:

File replacement was attempted on the protected system file c:\windows\system32\rundll32.exe. This file was restored to the original version to maintain system stability. The file version of the system file is 5.1.2600.5512.

Next, boot your system in Safe Mode or the Recovery Console so Windows File Protection is not running.

Again, rename or just delete your c:\windows\system32\rundll32.exe file so it is "missing".

Now your rundll32.exe file is really missing.  If Windows File Protection was running, the "missing" file would be quickly and silently replaced (try renaming or deleting it in normal mode and it will be replaced).

That is a critical XP system file, right?  It is on the list of 3498 file that Windows File Protection and the System File Checker knows about but now it is missing.

Now, with your system32/rundll32.exe file missing, boot in Normal mode and try to use something like control panel to open something like the Power Options and you will see this familiar message:

Control Panel

Windows cannot find 'C:\WINDOWS\system32\rundll32.exe'.  Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

Now you have recreated a common problem with the missing file and seen the error with our own eyes.  A Microsoft Support Engineer will usually suggest running sfc /scannow for this kind of problem, but it will not work or help and you can prove it to yourself.

With your still system booted normally,  next, run sfc /scannow to completion.

Take a look and you will see that the system32\rundll32.exe file is still missing, right?  

How can that be if sfc /scannow is supposed to replaces missing or corrupt system files?

Did running sfc /scannow replace the missing file?  No it did not.

Now you know what sfc /scannow does not do.  It does not replace missing or corrupt files from the system32 folders - you just proved it.

Why do you keep suggesting it?  It is just another wild goose chase.

Now go to c:\windows\system32\dllcache and delete or rename the rundll32.exe file from there - and it will stay gone and not be replaced since Windows File Protection does not look after the contents of the dllcache folder.

Run sfc /scannow to completion again.

This time, the missing rundll32.exe file in the dllcache folder will be replaced since that is the folder sfc /scannow cares about but the file will still not be replaced in the system32 folder since that is not what sfc /scannow does.

Now you know what sfc /scannow doesn't do and what it does do.

Be sure to put your "missing" rundll32.exe file back by either renaming it or replacing it from the backup copy in the dllcache folder.

Hi,

There is no command available to check only intact files. But if you have some corrupted Windows files you will be able to fix it by perform a System File Check.

Refer the link “How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows XP”, to perform System File Check.

**Note:**It may ask for Windows CD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.
