Microsoft rolled out the KB4480970 and KB4480960 update for Windows 7 SP1 earlier this week. The update addresses recently discovered security vulnerabilities and include bug fixes and performance improvements. But it may have worsened an already underlying issue with network devices on Windows 7 with the latest updates.
According to user reports, the KB4480970 and KB4480960 updates break sharing files over the network via SMBv2 and the Remote Desktop feature. The issue only occurs for Administrator accounts on Windows 7. For non-admin accounts, sharing still works fine.
Microsoft is yet to acknowledge the issue, but thankfully, folks on the internet have already found a fix for the problem through a simple registry edit.
How to fix SMBv2 network share and Remote Desktop issue on Windows 7 after update
- Open a Command Prompt window with Admin privileges.
- Issue the following command:
reg add HKLMSOFTWAREMicrosoftWindowsCurrentVersionPoliciessystem /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f - Reboot your PC.
Network sharing and Remote Desktop should now work on your PC running the latest Windows 7 update. Cheers!
