Windows 11 Safe Mode

The Windows 11 Safe Mode

There are several ways to start Windows 11 in a safe mode. Here is an overview. Note that this also applies for Windows 10.

After Windows 11 booted up, Safe Mode can be reached by using a shortcut key. If this still works with old versions of Windows, Windows 10 and 11 often fail because the user has only a short time to respond. When you start the PC, you normally need to simultaneously press the [Shift] and [F8] shortcut keys. But it's also easier if Windows 10 starts properly:

  1. Click the Windows button located to the right of the power button . If Windows restarts directly, it will also be in the bottom right corner of the start screen.
  2. The Restart option appears when clicking on the power button.
  3. Press and hold the Shift key and click with the mouse on Restart to access the UEFI menu .
  4. On the light blue background you can see if you are in the UEFI menu. Then select Troubleshooting .
  5. There you will find Advanced Options and here the Windows Startup Settings feature. Click on the button Restart .
  6. It takes a while for the emergency system to start. Press the F4 soft key to restart Windows in Safe Mode.

Start Windows 11 in safe mode

  1. In this menu, you need to hold down the Windows and R keys simultaneously to open the Run dialog.
  2. In this enter msconfig and press OK to start the system configuration.
  3. Above is the Start tab. Choose Safe Boot and Network .
  4. To enter Safe Mode, press the OK Button that Windows restarts.

You can also use Safe Mode at the command prompt cause.

  1. If you press the windows and x keys at the same time, you have a shortcut menu
  2. After you select Command Prompt (Administrator) , confirm the security prompt by clicking OK.
  3. To start Windows in safe mode, then enter the command bcdedit set {current} safeboot network .

You can also create a desktop shortcut to safe mode so that you see an icon on your desktop that will help you get into safe mode quickly.

  1. To do this, right-click on an empty area (where there are no icons or other) and select New and then Link .
  2. Enter shutdown.exe / r / o / f t 00 as the path here. Then click Next and then Finish .
  3. If you click this Icon shutdown.exe in the future, Windows will start directly in Safe Mode.

Using the Windows 11 DVD to restore

If Windows does not boot from the hard disk and you have the Windows 11 DVD at hand, the item Computer Repair will appear after loading the DVD to repair Windows.

If all these tips fail, you may be able to send your computer to the manufacturer for repair. However, if the computer is older and there is no longer a guarantee, it is not recommended. Consider purchasing a new computer, which usually works right after it starts up.

History of wordprocessors and spread sheets

Word processors, spreadsheets and databases are everywhere today. Modern economy would break down otherwise if going back to pencil and paper. Makes one wonder how economy was able to exist before the event of computer programs doing the tedious work for us. Here's the short but incomplete history of how it all began. More, how so often not the first software of its kind made the big money but these being improved, or just clever advertised.

It's the 1970s and computers were found only in large companies and universities. Enthusiasts had virtually no change to get their hands on one unless being in one of these universities or large firm. In offices you had typewriters, if lucky an IBM Selectric. While there was Tipex and other methods to correct already printed text it was tedious and cost time. A good typist could probably type 100 letters in the time needed to correct the mistake. To have an electronic word processor would be nice, but that only existed in large companies. Otherwise you had line editors. Early programs such as ed would actually only show one line.

The ground for electronic word processors was laid 1975 when MITS pushed the Altair 8800 on the market. Even though it was merely a box filled with electronics but without keyboard or monitor computer nerds went nuts being able to finally own their personal computer.

Two years later the first real home computers entered the market and kicked off the home computer revolution. Named 1977  Trinity by the BYTE magazine, the Radioshack Tandy TRS-80, the Commodore PET and the Apple 2, all of which came with a keyboard and monitor or could be attached to one. Now software companies saw huge potential and wrote many application for the various machines including word processors. It also produced the world's first Killer App when VisiCalc, one of the first electronic spreadsheets, entered the market. People and small offices who never used computers before bought an Apple ][ to be able to use VisiCalc.

The next leap happened 1981 when the Osborne Computer Corporation sold the first portable computer going by the name of Osborne 1. Well "e;portable" if one had strong arms to carry the some 30 pounds heavy box around. But you could do this if you wanted, put it into a plane to visit a company branch or attend a meeting. The hardware was not that amazing but the fact it was portable. May be more interesting was the office suite coming with it. The price for the software if bought separately would be almost as much what the Osborne 1 with it cost.

The software consisted of the WordStar word processor, the spreadsheet SuperCalc and databases, the program language BASIC and even a few games. While neither WordStar nor SuperCalc were the first of their kind. These were the already mentioned VisiCalc for the spreadsheet and Electric Pencil is widely regarded to be the first electronic word processor for home computers. The idea of bundling single software application into one suite and offer it with the hardware made this computer a runaway success.

While Microsoft focused since the mid 70s on selling their BASIC, which was shipped with almost every home computer from back of the day and in the 80s in creating MS DOS for the IBM PC it took them until 1990 to see the potential of bundled office software, although their word processor, spreadsheet and other components of the later Microsoft Office were available as separate products before that.

Note that I unfortunately do not own an Osborne I or other vintage hardware. Thus I emulate them with the M.A.M.E. emulator which not only allows to emulate long faded to obscurity hardware, but also most of the video arcade games in existence since 1975, when the first games ran on a CPU microprocessor.
