The most alternative restorer for Windows XP operating system

        In addition to the system restore function, System File Checker (Sfc.exe) can be regarded as the most original Windows system restore tool. Windows XP's System File Checker scans all protected system files to verify their version, as well as setting the file cache size, clearing the file cache, and repopulating the "%SystemRoot%\\System32\\Dllcache" folder. To enable the System File Checker in Windows XP, first run the Command Prompt: Click Start → All Programs → Accessories → Command Prompt, or click the Start → Run command on the command line. Type "cmd" and press Enter. Then type "Sfc" at the cursor prompt in the Command Prompt window and press Enter.

Disc to repair or replace incorrect files. If the Dllcache folder is corrupted or unavailable, you can also use the "Sfc/scanonce" or "Sfc/scanboot" command to fix the contents of the folder to ensure the security and stability of the system. Tip: In Windows 98, we can click Start → Programs → Accessories → System Tools → System Information, and then click Tools → System File Checker.
