How Do I Fix Microsoft Windows Search Indexer’s High CPU Usage?

SearchIndexer.exe is responsible for indexing files on your computer. As you may already know, indexing means scanning through every file on your hard drive and storing its contents in a database.

This is necessary because if you were to open any document on your computer without searching for it beforehand, you’d waste hours trying to find it. So, whenever you save a new document, it automatically gets added to the database.

However, SearchIndexer.exe doesn’t stop once it finishes indexing files. Instead, it continues to run in the background, constantly searching through your entire system.

That’s why it uses so much memory and processor power. Because of this, SearchIndexer.exe can cause your PC to freeze or crash, even the search box hangs.

To fix this problem, you should try to disable the service altogether. However, if you do that, you’ll lose access to all of your indexed documents. So instead, we suggest using a third-party utility called CCleaner. It allows you to remove unnecessary files and programs from your computer. Once you’ve done that, you can reenable the SearchIndexer.exe service.

Once you’ve disabled the service, you can start the program again and let it finish indexing your files. Then, you can delete the temporary files created by the program.
