Question: How to return to the previous system after upgrading?
A small number of nostalgic netizens said that they could not adapt to the new system and urgently needed to return to the original system. Fortunately, Windows 10 has its own backtracking function. Users only need to click on the operation center icon in the lower right corner of the Windows 10 desktop to enter all settings. Then select Update, Security, and Recovery in turn, and finally click the Start button under Windows 7.
Next, the user can follow the system prompts to perform related operations. Click Next three times, and after returning to Windows 7 1 time, the computer will automatically start the system restore, which lasts for about 20 minutes. Please be patient.
In addition, experts suggest that the "fallback function" of Windows 10 system needs folders of $Windows~BT and Windows.old under the system disk, and users can copy them to storage devices for backup after upgrading Windows 10. Because if they are cleaned or deleted, the computer cannot be pushed back to the previous system.
The second question: I can't open the webpage, and I can't use QQ, Popular, Thunder and other software.
Just after the release of Windows 10, some netizens reported that their QQ, popularity, thunder and webpage could not be used normally. According to experts, this is because the LSP program is not normal. The solution is actually very simple: open the 360 security guard, click the more button in the lower right corner, and search for LSP repair in the upper right corner of the page that appears later.
After the search is completed, the LSP repair tool page will pop up. Users can click "Fix Now" in the lower right corner, and then click "OK" after requesting to complete the whole repair process. After the repair is completed, the browser can open the webpage normally, and third-party software such as QQ and Thunder can also be used online normally.
Three questions: setup, email and other system built-in programs can't be opened.
"Unable to open xx with the built-in administrator account", users will have a certain probability to see this prompt when entering settings, emails, contacts and other programs. According to expert analysis, this is because by default, Windows 10 system does not allow users with built-in administrators to access built-in programs and setting options.
"This is the legacy of Windows 7 and Windows 8," the expert said, because in the old system, the administrator user identity was used; However, Windows 10 system needs to log in through "Microsoft account" to use these built-in programs normally.
To solve this problem, users have two choices: first, log on to the Microsoft account registration website: /signup.aspx? bk= 1429 165067。 ru =/log in . SRF % 3 fmkt % 3d zh-CN % 26lc % 3d 2052% 26bk % 3d 1429 165067 & amp； uiflavor = web & ampuaid = 6fd 6775d 5 15f 4238 a08d 3 1 e 33 aa 2f 35d & amp； ZH。 Lc = 2052 & ampLic= 1, register Microsoft account; The second is to change permissions.
The following is a detailed description of the second method. Press Win+R to enter the "Run" window, enter gpedit.msc, and press enter. After that, the local group policy editor dialog box pops up on the left, click Computer Configuration, Windows Settings, Security Settings, Local Policy and Security Options, and then double-click User Account Control: the administrator approval mode with built-in administrator account is changed to Enabled. After completing the above steps, restart the computer to use the built-in program normally.
Question 4: How to modify the default browser in Windows 10 system?
As a brand-new operating system, the interface of Windows 10 has changed a lot, and many users don't know where to set their favorite browser as the default browser. Experts suggest that 360 security guards can be used to solve this problem quickly.
After opening 360 Security Guard, click More in the lower right corner of the interface, and then search for default software in the upper right corner. After pressing Enter, you can enter the Default Software Settings page. At this point, users can not only change the default browser, but also change the default player, default mailbox and other options.
Five questions: How to adjust the screen resolution?
After the system is updated, the first thing to do is to change to a clearer (higher) resolution. But without guidance, it is not easy to find solution options.
It is reported that users need to click the notification center icon in the lower right corner of the screen and select all settings; Then click on the system to enter the system settings menu, find the advanced display settings in the display options and press enter, and you can choose a more suitable resolution setting.
Experts remind that if the screen resolution window is gray in the advanced display settings page, it means that the driver is not installed correctly on the graphics card of the current computer. Users can continue to change the screen resolution after using software such as 360 Driver Master to update the graphics card driver that better matches the Windows 10 operating system.
Six questions: SQL software startup error
After upgrading Windows 10, there will be a pop-up window to prompt SQL software error every time you boot? Don't worry, it's just because SQL server software still has compatibility problems in Windows 10: When the system before the upgrade contains SQL server software, this error prompt will appear after the upgrade.
Users can use the optimization and acceleration function of 360 Security Guard to solve this problem: after opening 360 Security Guard, enter the optimization and acceleration interface and click the startup option in the lower right corner. Find "SQL Service Manager" in the startup item list and select Disable; Similarly, repeat the above operations in the list of application services to find and disable the SQL Service Manager.
Question 7: After upgrading to Windows 10, the previous operating system version is still displayed in the system properties.
Some netizens asked, after the upgrade, I checked the computer properties and still displayed the old system version. Does this mean that the upgrade has not been completed? Netizens don't have to worry, this is just because most computers use the GHOST system, and after installation, they will write their "private information" into the registry, such as the GHOST system of Fenglin Volcano and the GHOST Windows 7 system of Rainforest Wind.
However, the upgraded installation of Windows 10 did not clean up this part of the registry content, which led to the failure in the figure. The solution is still very simple, press Win+R to run, enter Regedit, and press enter; After that, the system will open the Registry Editor, and users only need to find HKEY_LOCAL_MACHINE, SOFTWARE, Microsoft, Windows, CurrentVersion and OEMInformation folders in the left window.
Eventually, after the user deletes the OEMInformation folder, the system version will be restored to the latest.
Eight questions: The system's built-in graphics driver is incompatible.
After upgrading Windows 10, problems such as screen flicker, blurred mouse pointer, and inability to adjust screen resolution occasionally happen to netizens. In fact, the source of this problem comes from the incompatibility between the built-in graphics card and the driver. The reason has been briefly introduced in the last article, that is, Windows 10 system has not provided a perfect driver scheme for a small number of graphics cards.
Some experts said that the easiest way to solve this problem is to search and use the "driver master" program in 360 security guards. It is understood that the driver master embedded in 360 has fully supported the Windows 10 operating system, providing users with the most compatible driver version under the Windows 10 system. Users only need to select Start, and the most suitable driver version will be automatically matched and pushed.
Question 9: The text of third-party software such as QQ is seriously blurred.
After the update of Windows 10, a considerable number of netizens reported that the characters in QQ and other software were seriously blurred. This is because in the Windows 7 era, many netizens used to adjust the font to 125% or even 130%. However, when the system was upgraded to Windows 10, these settings were used, and the fonts were "weak" due to compatibility problems.
So just change the font back to 100%. Click the notification center icon in the lower right corner of the screen to enter all settings; Then find the system in the "Setup Menu" and click to enter the system setup menu. After entering the system setting menu, pull the slider as shown in the figure to the far left, and the font can be adjusted back to 100%, thus solving the problem of fuzzy font.
Question 10: How to expand the space to upgrade Windows 10?
Answered a lot of questions from upgraded users, and the last question was reserved for Microsoft users who have not upgraded yet. Microsoft Center shows that Windows 10 system needs at least 16 GB of system disk remaining space. Although this condition is not harsh, there are still quite a few users in China who can't enjoy the benefits of free upgrade because of this restriction.
So the computer expert's suggestion to the user is: click more options in the lower right corner of the 360 security guard interface, enter "slimming system disk" in the search bar and press enter. Immediately after that, the "system disk slimming software" with the function of cleaning the system disk was started, which released a lot of memory space for users.
It is reported that the free upgrade period of Microsoft Windows 10 is only one year, and users who upgrade after one year still have to pay the upgrade fee. Therefore, IT practitioners suggest that the majority of netizens complete the upgrade as soon as possible during the one-year free period; And because counterfeit and pirated Windows 10 installation packages have flowed out in the market, security experts suggest that netizens choose Microsoft official or 360 and other authorized third-party channels to upgrade their systems, and beware of downloading upgrade packages containing malicious programs.
