Windows 7 I need help with my laptop

It sounds like your system might be experiencing serious issues due to unintended changes in the Windows Registry and system files. Here are some steps you can try to resolve the problems: 1. System Restore: - If System Restore was enabled before these issues occurred, you could try to revert your system back to a point before you made these changes. - To access System Restore in Windows 7: Start Menu > Accessories > System Tools > System Restore. 2. Startup Repair: - Boot your computer and press F8 repeatedly to access Advanced Boot Options. - Choose "Repair Your Computer" and then select "Startup Repair." Follow the on-screen instructions. 3. Safe Mode: - Try booting your computer into Safe Mode to see if you can access your files and perform any corrective actions. 4. Windows 7 Repair Installation: - If none of the above steps work, you might need to perform a repair installation of Windows 7. Insert a Windows 7 installation disc and boot from it to start the repair installation. - The repair installation keeps your programs, files, and settings intact but repairs Windows itself. 5. Backup Important Data: - While attempting the above, ensure you have a backup of your important files and data to prevent any potential loss during the procedures. 6. Professional Assistance: - If you are uncomfortable performing these steps or unsure about the procedures, consider reaching out to a professional technician for assistance. Make sure to follow these steps carefully and consider seeking professional help if needed to avoid further complications.
