How to protect windows files

The reason for this is that the files in the dllache folder under windows are missing.

First: You may have downloaded the sp2 patch,

Second: A pirated disc is used but the disc version is inconsistent,

Third: If you installed a time-limited version, you can check it yourself.

Windows file protection is a measure taken to prevent other programs from modifying or deleting important windows files. Once discovered, it will be overwritten with the original file of dllache. Generally, this folder is several hundred M in size. The corresponding windows provides the sfc command to perform file management operations.

sfc [/scannow] [/scanonce] [/scanboot] [/revert] [/purgecache] [/cachesize=x]

parameter

/scannow

Scan all protected system files immediately.

/scanonce

Scan all protected system files at once.

/scanboot

Scan all protected system files every time the computer is restarted.

/revert

Return scanning to default operation.

/purgecache

Immediately clear the "Windows File Protection" file cache and scan all protected system files.

/cachesize=x

You must be logged in as a member of the "Administrators" group to run sfc.

If sfc finds that a protected file has been overwritten, it will retrieve the correct version of the file from the %systemroot%\system32\dllcache folder and then replace the incorrect file.

If the %systemroot%\system32\dllcache folder is damaged or cannot be used, use sfc /scannow, sfc /scanonce or sfc /scanboot to repair the contents of the Dllcache directory.

So the final reason why you are asked to insert the xp disc is that the dllache folder does not have the original file. In this case, you have to obtain it from the xp disc.

However, if the system prompts "The files required to run Windows normally have been replaced with unrecognized versions", then you can ignore it. Generally, there will be no problem. However, for safety reasons, it is recommended to restore to the original file.
