Start with the problem you can observe—such as missing files, a failed update, no sound, or a printer that will not print—and use the narrowest relevant fix. First note whether the problem began after a full Windows version upgrade or a later update, whether it affects one app or device or the whole PC, and whether Windows still starts. Back up important files before recovery steps that could remove data.
Before troubleshooting, identify what changed
A feature upgrade changes Windows to a newer version; a later update may install on the version already running. That distinction matters: uninstalling a recent update and going back to the previous Windows version are different recovery options. If you can sign in, type winver in Start and note the version and build. Also write down any exact error code and whether the issue affects one device or app or the whole PC.
Windows 10 support ended on October 14, 2025. Microsoft says standard free software updates, technical assistance, and security fixes for Windows 10 ended on that date. That support change does not identify the cause of an individual upgrade problem, but it matters when deciding whether to keep using that Windows version.
Fix a failed or stuck Windows Update
- Open Settings > System > Troubleshoot > Other troubleshooters in Windows 11, then select Run beside Windows Update. In Windows 10, open Settings > Update & Security > Troubleshoot > Additional troubleshooters and run Windows Update. Labels can vary by release.
- Restart the PC and check Windows Update again. If installation remains stuck at 0% or 100%, or fails with an error, record the code rather than repeatedly applying unrelated fixes.
- Use Microsoft’s steps for the displayed code. Microsoft lists possible causes—not definitive diagnoses—including corrupted update files or cache (
0x8007000d), an installation taking too long or being interrupted (0x800705b4), an incomplete update or connection issue (0x80240034), low disk space or a component-related issue (0x800f0922), and a potentially incompatible driver (0xC1900101).
If Microsoft’s guidance points to corrupted cached update files, its advanced cache-clearing procedure stops the Windows Update service, clears the contents of C:WindowsSoftwareDistribution, then starts the service again. Follow Microsoft’s current instructions for that procedure; do not delete other Windows folders. Back up important files before moving on to recovery actions.

Find files that seem to have disappeared
- Open File Explorer, select This PC, and search for the filename. If you do not remember the full name, search by file type, such as
*.doc. - If File Explorer finds the file, use Open file location to see where it is now. Also check whether hidden files are affecting what you can see.
- For a file stored in OneDrive, use OneDrive’s separate lost-file recovery steps.
A search that finds nothing does not by itself prove that a file was deleted.
Fix an activation notice
- Check the installed Windows edition and version. Use
winverfor the version; compare the installed edition with the edition covered by your license. - Open Settings > System > Activation in Windows 11, or Settings > Update & Security > Activation in Windows 10. Run the Activation troubleshooter if it is offered. Microsoft’s Windows 11 troubleshooter requires administrator access and an internet connection.
- Follow the guidance for the exact activation error. Some errors can relate to a device change, a missing or invalid product key, or an edition mismatch. Check whether your existing digital license applies before considering another key.
Restore sound after an update
- Check for pending Windows updates, install applicable updates, and restart.
- Open Device Manager and check whether the audio device appears and is enabled. Update its driver.
- If the problem began after a recent update and a previous driver is available, open the device’s driver properties and select Roll Back Driver.
- If sound still fails, Microsoft also recommends restarting the Windows Audio and Windows Audio Endpoint Builder services. If Windows does not find the needed driver, check the official support page for the PC or audio-device manufacturer and the exact model.
Get a missing or non-printing printer working
- Run the printer troubleshooter. Check that the printer is powered on and that its USB, Wi-Fi, or Bluetooth connection is working.
- If a print job is stuck, investigate the print queue and Print Spooler rather than reinstalling unrelated Windows components.
- Check Windows Update for a printer driver, or follow the printer manufacturer’s instructions for your model.
- On some ARM-based PCs, Microsoft advises using Settings > Bluetooth & devices > Printers & scanners > Add device instead of the manufacturer’s installer, unless the manufacturer gives different guidance.
Fix Wi-Fi or other network problems
Start with the targeted Wi-Fi checks and available Windows updates. Save Network reset for a last resort: it removes and reinstalls network adapters and resets their settings. Afterward, you may need to reinstall or configure VPN clients, Hyper-V virtual switches, or other networking software, and the PC’s network profile may change.

Repair an app that stopped working
An app may stop working because the new Windows version changes the operating-system architecture or security environment, or because the app no longer meets its system requirements. Check for a supported update from the app’s publisher and use the app’s compatibility troubleshooting steps. Some software may not support the new Windows version. For Microsoft Store apps, check for updates in Microsoft Store.
Choose the least disruptive recovery option that fits
Try a suitable troubleshooter first when Windows starts. Before using recovery, back up important files; the impact depends on the option selected. These choices solve different problems and are not interchangeable.
