This process includes stopping essential update services, renaming or deleting the SoftwareDistribution and Catroot2 folders (which store update files and signatures), and restarting the services. Here is a detailed sequence:
- Open Command Prompt as an administrator.
- Stop the update services by running:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver - Rename the update cache folders:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old - Restart the services:
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
By renaming these folders, Windows will recreate them fresh during the next update attempt, eliminating corrupted files or incomplete downloads that might have triggered the error. This approach is often effective, especially when the update cache becomes a source of conflict.
It is important to note that during this process, active downloads or pending updates will be cleared, so you may need to reinitiate the update after completing these steps.
Checking System Files with SFC and DISM Tools
Corrupted or missing system files are a frequent culprit behind the 0x80070001 error. To address this, Windows provides two powerful command-line utilities: the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tool. These utilities scan and repair system file integrity, ensuring that critical components required by Windows Update function correctly.
Start with the SFC tool, which inspects protected system files and replaces damaged versions with cached copies. Open an elevated Command Prompt and execute:
sfc /scannow
fszf
This process may take several minutes to complete. Upon finishing, the tool will report whether it found and repaired any issues. If problems are detected but not fixed, proceed with the DISM tool, which can repair the underlying Windows image used by SFC.
Run the following commands sequentially:
DISM /Online /Cleanup-Image /CheckHealth– Checks for corruption.DISM /Online /Cleanup-Image /ScanHealth– Performs a more detailed scan.DISM /Online /Cleanup-Image /RestoreHealth– Repairs the image.
RestoreHealth is the most critical step, as it attempts to download and replace corrupted files from Windows Update servers. Once complete, it is advisable to rerun sfc /scannow to ensure all issues are resolved.
These tools are indispensable for maintaining system stability and are often the key to resolving stubborn update errors that stem from file corruption or misconfiguration. As Mark Russinovich, a renowned Windows expert, notes:
